Introduction 1.1 Research background and significance
Soil erosion is one of the serious environmental problems facing the world, which has caused serious damage to farmland, water resources and ecosystem.As a comprehensive control measure, ecological engineering of soil and water conservation has important application value and significance.Therefore, the purpose of this study is to explore the application of soil and water conservation ecological engineering in soil erosion control, and to provide scientific basis and technical support for solving soil erosion problems.
First of all, soil erosion has a serious impact on farmland output and agricultural sustainable development.Soil erosion leads to the decline of soil quality and soil fertility, which further affects the growth and yield of crops.Ecological engineering of soil and water conservation can improve soil structure and vegetation coverage, improve soil water-holding capacity and anti-erosion ability, thus reducing the occurrence of soil erosion, protecting farmland resources and increasing crop yield.
Secondly, soil erosion poses a serious threat to water resources and water environment.Soil erosion leads to the loss of nutrients, pesticides and other pollutants in soil into water bodies, which pollutes water resources and destroys the balance of water ecosystem.Ecological engineering of soil and water conservation can reduce the loss of nutrients and pesticides, improve the quality of water bodies and protect water resources and aquatic ecosystems through vegetation restoration and soil improvement.In addition, soil erosion has a negative impact on biodiversity and ecosystem functions.Soil erosion leads to vegetation destruction and soil erosion, which in turn destroys biodiversity and ecosystem stability.Ecological engineering of soil and water conservation can promote the restoration of biodiversity and the healthy development of ecosystem and maintain ecological balance through vegetation restoration and ecological restoration. [1]herefore, it is of great scientific significance and practical value to study the application of soil and water conservation ecological engineering in soil erosion control.Through in-depth discussion and analysis of the principles and technical measures of soil and water conservation ecological engineering, it can provide scientific basis and technical support for soil erosion control, and provide important reference for realizing sustainable development of farmland, water resources protection and ecological environment restoration.

Research purpose
This paper aims to analyze the application of soil and water conservation ecological engineering in soil and water loss control, summarize the present situation and progress of related research, and discuss the principle and mechanism of soil and water conservation ecological engineering and its role in soil and water loss control.The direction and suggestions for further research are put forward to provide scientific basis and technical support for soil erosion control.

Impact of Vegetation Restoration on Soil and Water Conservation
Vegetation restoration is one of the important measures in soil and water conservation ecological engineering, which has a significant impact on soil and water conservation.First of all, vegetation restoration can effectively reduce the occurrence of soil erosion.The roots of vegetation can firmly fix soil particles and prevent them from being washed by water flow and wind erosion.The dense coverage of vegetation can block the direct impact of rain and slow down the impact of raindrops on soil, thus reducing the risk of soil erosion.In addition, the branches and leaves of vegetation and ground cover can intercept the sediment particles in rainwater, prevent them from entering the water body, and protect the quality of water resources.Secondly, vegetation restoration can improve soil water-holding capacity and anti-erosion ability.Vegetation can improve the structure and texture of soil and increase the porosity and water holding capacity of soil through the growth and secretion of substances by roots.The roots of vegetation can also increase soil erosion resistance, prevent water erosion and wind erosion, and reduce soil loss and erosion.In addition, vegetation restoration can also promote soil organic matter accumulation and nutrient cycle.Plants absorb carbon dioxide through photosynthesis and convert it into organic matter, which is then released into the soil.These organic substances can improve soil fertility and nutrient content, and promote soil microbial activity and nutrient cycle.At the same time, the roots of plants can also secrete organic acids and enzymes to promote the release and transformation of nutrients in the soil.Finally, vegetation restoration can improve the ecological environment and contribute to soil and water conservation.Vegetation restoration can provide good habitats and habitats and promote the increase of biodiversity.The increase of biodiversity can improve the stability and anti-interference ability of ecosystem and reduce the influence of external factors on soil and water conservation.

Key technologies and methods of vegetation restoration
Vegetation restoration is one of the important means in ecological engineering of soil and water conservation.By selecting plant species reasonably and adopting appropriate technical methods, the occurrence of soil erosion can be effectively reduced.First of all, according to the climatic conditions, soil types and soil erosion degree in different regions, select vegetation types with strong adaptability and good stress resistance.Secondly, the proportion and planting density of different plants should be rationally allocated to achieve the best soil and water conservation effect.In addition, scientific management measures include regular pruning, fertilization and irrigation to maintain the healthy growth and coverage of vegetation.The selection and implementation of key technologies and methods of vegetation restoration need to comprehensively consider the characteristics of the control area, plant ecology knowledge and engineering technical requirements.By reasonably selecting plant species, configuration and layout, strengthening plant conservation and management, and monitoring and evaluating vegetation, effective management and management of soil and water conservation ecological engineering can be realized, and the occurrence of soil erosion can be reduced. [2]

Application Analysis of Vegetation Restoration
Through the analysis of vegetation restoration cases at home and abroad, it can be found that the application of vegetation restoration technology in soil erosion control has remarkable effects.For example, in the Loess Plateau, by adopting reasonable vegetation allocation and planting density and introducing herbs and shrubs, the occurrence of soil erosion can be effectively reduced.In coastal areas, by planting sand plants and establishing sand-fixing vegetation belts in sand dunes, wind-blown sand invasion and desertification expansion can be effectively prevented.These cases show that vegetation restoration technology has wide applicability and feasibility in different regions and environmental conditions.
In a word, vegetation restoration technology is an important control means in soil and water conservation ecological engineering and plays an important role in soil and water loss control.By selecting suitable vegetation types, rational allocation and scientific management, soil erosion can be effectively reduced and the quality of soil and water resources can be protected.However, it is necessary to further study and explore the best practice and adaptability of vegetation restoration technology under different regional and environmental conditions in order to improve the governance effect of soil and water conservation ecological engineering.

Impact of soil improvement on soil and water conservation
Soil improvement is one of the important measures in the ecological engineering of soil and water conservation.By improving the physical, chemical and biological properties of soil, the water retention capacity, erosion resistance and fertility of soil can be improved, thus effectively reducing the occurrence of soil erosion.First of all, soil improvement can improve the water retention capacity of soil.Soil improvement techniques commonly used in soil and water conservation ecological engineering include organic matter addition, lime application and mineral addition.The addition of organic matter can improve soil structure, increase soil porosity and pore connectivity, and improve soil water retention capacity.The application of lime can adjust the acidity and alkalinity of soil, improve the structure of soil and increase the water absorption capacity of soil.The addition of minerals can improve the texture and structure of soil, increase the porosity of soil and promote the water retention capacity of soil.Through these soil improvement measures, the water loss in the soil can be reduced and the water use efficiency of the soil can be improved.Secondly, soil improvement can improve soil erosion resistance.Soil erosion is mainly caused by hydraulic erosion and wind erosion, and soil improvement can improve soil erosion resistance and reduce the risk of soil erosion.For example, the addition of organic matter can increase the viscosity and cohesiveness of soil, enhance the impact resistance of soil and reduce the occurrence of hydraulic erosion.The addition of minerals can increase the clay content of soil and improve the wind erosion resistance of soil.In addition, soil improvement can also increase the shear strength and compressive strength of soil and reduce gully erosion and slope erosion of soil.Finally, soil improvement can improve soil fertility.Soil improvement measures in soil and water conservation ecological engineering can not only improve soil physical properties, but also improve soil chemical properties and increase soil nutrient content and nutrient supply capacity.The addition of organic matter can increase the content of organic matter in soil and improve soil fertility.The addition of minerals can increase soil nutrient content and improve soil fertility.Through soil improvement, soil fertility level can be improved, plant growth and development can be promoted, vegetation coverage can be increased, and the occurrence of soil erosion can be reduced.

Key technologies and methods of soil improvement
Soil improvement is an important link in the ecological engineering of soil and water conservation.By improving the structure and quality of soil, the water-holding capacity, erosion resistance and fertility of soil can be improved, thus reducing the occurrence of soil erosion.In soil erosion control, the key technologies and methods of soil improvement include organic matter addition, mineral addition, soil consolidation and improvement, soil remediation and so on.Organic matter addition is a common soil improvement method, which can improve soil structure and fertility and increase soil water holding capacity by adding organic fertilizer and straw.Mineral addition is to adjust the pH and nutrient content of soil by adding minerals such as lime and phosphate fertilizer, and improve the fertility and anti-erosion ability of soil.Soil consolidation and improvement is a method to improve the physical properties and anti-erosion ability of soil through soil curing agent, which can reduce wind erosion and water erosion of soil.Soil remediation is a method of repairing and restoring polluted or degraded soil, which can repair the structure and function of soil and improve its waterholding capacity and anti-erosion ability.

Application Analysis of Soil Improvement
In order to verify the application effect of soil improvement technology in soil erosion control, this chapter will show the practical application of soil improvement through case analysis.For example, the soil in a certain area is barren and lost due to long-term cultivation and water erosion.In order to improve the quality and structure of soil, organic matter addition and soil consolidation are adopted.By adding organic fertilizer and straw, the organic matter content of soil is increased, the structure and fertility of soil are improved, and the water holding capacity of soil is improved.At the same time, the soil consolidation agent is used to consolidate and improve the soil, which increases the stability and anti-erosion ability of the soil.After a period of implementation and observation, it is found that the quality of soil has been obviously improved, the situation of soil erosion has been obviously reduced, and the fertility and water use efficiency of soil have also been improved.
Soil improvement technology has remarkable application effect in soil erosion control.By improving the quality and structure of soil, improving the water-holding capacity and anti-erosion ability of soil, the occurrence of soil erosion can be effectively reduced, soil resources can be protected, and land use efficiency can be improved.

Impact of water resources management on soil and water conservation
Water resources management plays an important role in soil and water conservation ecological engineering, which can have a positive impact on soil and water conservation.First of all, water resources management can reduce the occurrence of soil erosion through reasonable water regulation.In the ecological engineering of soil and water conservation, through reasonable irrigation and drainage measures, the water supply of farmland can be guaranteed and excess water can be eliminated, thus reducing the water saturation and infiltration of soil and reducing the risk of soil erosion.For example, through precision irrigation technology and drip irrigation technology, the waste of water and the risk of leaching soil can be reduced, and the water retention capacity and erosion resistance of soil can be improved.Secondly, water resources management can also reduce soil erosion through reasonable soil and water conservation measures.Soil and water conservation measures include building soil and water conservation facilities, building slope protection and revetment, and carrying out publicity and education on soil and water conservation.These measures can effectively prevent soil erosion and protect the quality of soil and water resources.For example, setting ditches and terraces in farmland can slow down the water flow and reduce the risk of soil erosion; At the same time, publicity and education on soil and water conservation can improve farmers' awareness of soil and water conservation and promote the development of soil and water conservation work.In addition, water resources management can also promote soil and water conservation through water quality protection.Water quality protection includes measures such as reducing the discharge of agricultural and industrial wastewater and strengthening water pollution control.By protecting water quality, we can reduce the erosion and damage of pollutants in water to soil and protect the health of soil and water resources.For example, rational use of pesticides and fertilizers in farmland to reduce the pollution of pesticides and fertilizers to soil and water bodies; At the same time, strengthen wastewater treatment and discharge control in industrial production to reduce the pollution of wastewater to water and soil. [4]

Key technologies and methods of water resources management
In water resources management, there are some key technologies and methods that can be applied to soil erosion control.First of all, reasonable irrigation technology is an important part of water resources management.By accurately measuring soil moisture and plant water demand and carrying out accurate irrigation, water waste can be minimized and the risk of soil erosion can be reduced.Secondly, water resources management can also regulate the flow and distribution of water and reduce the occurrence of soil erosion by establishing soil and water conservation facilities and soil and water conservation projects, such as canals and dams.In addition, scientific and reasonable formulation of water resources management policies and measures, and strengthening the protection and management of water resources are also the key to soil erosion control.

Application Analysis of Water Resources Management
By analyzing the application cases of water resources management in soil erosion control, we can better understand its effect and function.For example, in the management of a river basin, the occurrence of soil erosion is effectively reduced by building canals and dams to regulate the flow and distribution of water.In addition, in farmland irrigation, precision irrigation technology is used to irrigate according to the water demand of plants, which effectively improves the vegetation coverage and reduces the risk of soil erosion. [5]hrough the above case analysis, it can be concluded that water resources management plays an important role and effect in soil erosion control.Scientific and rational management and utilization of water resources can reduce the risk of soil erosion, protect the quality of soil and water resources, and achieve the goals of sustainable development and ecological environment protection.
To sum up, the application of water resources management in soil erosion control is an important work.By reasonably regulating the distribution and utilization of water and adopting scientific irrigation technology and water resources management measures, the occurrence of soil erosion can be effectively reduced and the quality of soil and water resources can be protected.However, water resources management still faces some challenges and problems, such as the shortage and pollution of water resources.Therefore, it is necessary to further strengthen research and practice, put forward more scientific and feasible water resources management strategies and measures, and provide better technical support and guidance for soil erosion control.

Direction and suggestions for further research
On the basis of this study, there are some further research directions and suggestions, which can further improve and expand the application of soil and water conservation ecological engineering in soil erosion control.
Firstly, the effect and mechanism of vegetation restoration technology in soil and water conservation ecological engineering can be further studied.At present, vegetation restoration has achieved certain results in soil erosion control, but there are relatively few studies on the adaptability of different regions and ecological environment.Therefore, we can further explore the effects of different vegetation types and planting densities on soil and water conservation, and the mechanism of vegetation restoration on soil erosion and water quality improvement.Secondly, we can further study the optimization and innovation of soil improvement technology in soil and water conservation ecological engineering.Soil improvement is an important part of soil and water conservation ecological engineering, which can improve the structure and quality of soil, and improve its water retention capacity and erosion resistance.Future research can further explore the effect comparison of different soil improvement materials and methods, and the influence of soil improvement on soil microbial community and soil ecological function.In addition, the application strategies and technologies of water resources management in soil erosion control can be further studied.Scientific and reasonable water resources management has an important influence on the effect of soil and water conservation ecological engineering.Future research can further explore the effect evaluation and optimization of different water resources management models, as well as the synergy between water resources management, vegetation restoration and soil improvement.Ecological engineering of soil and water conservation is not only of great significance to the environment, but also has great economic and social benefits to agricultural production and eco-tourism.The future research can explore the evaluation method and index system of social and economic benefits of soil and water conservation ecological engineering in combination with actual cases, and provide scientific basis and decision support for decision makers.
In a word, there are still many directions worth exploring in the application research of soil and water conservation ecological engineering in soil and water loss control.Through further research and practice, the governance effect of soil and water conservation ecological engineering can be further improved, and greater contributions can be made to the realization of sustainable development and ecological environment protection.
