Introduction
The application of the concept of sponge city in the landscape construction of rural tourist destinations provides us with valuable enlightenment.By paying attention to ecological priority, resource recycling, sustainable development, community participation, education and publicity, we can create more beautiful and sustainable rural tourist attractions and provide better tourism experience [1].These revelations can not only protect and restore the natural ecosystem, but also improve the utilization efficiency of water resources, balance the development of economy, society and environment, increase the sense of participation of community residents and raise public awareness of environmental protection.Let's learn from the concept of sponge city, contribute our wisdom and strength to the landscape construction of rural tourist destinations, and jointly realize the sustainable development of rural tourism.

Sponge city concept
The concept of sponge city is a sustainable urban planning and design concept, which aims to transform the city into a "sponge" that can independently treat and utilize rainwater by simulating the natural ecosystem (Figure 1), so as to solve the problems faced by the city such as flood, water pollution and urban heat island effect [2].The concept of sponge city originated from the Netherlands.With the acceleration of urbanization and climate change, more and more cities began to pay attention to and adopt this concept.The core idea of sponge city is to improve urban water environment and ecological environment through diversified water resources management, natural ecological restoration and urban greening.In sponge city, a series of measures are taken to realize the collection, storage and utilization of rainwater [3].For example, by building rainwater gardens, green roofs, rainwater collection systems and underground water storage facilities, rainwater will be led to underground storage and used when necessary, such as irrigation, toilet flushing and fire fighting.This can not only reduce the load of urban drainage system, but also improve the utilization efficiency of water resources.Sponge city also emphasizes ecological restoration and urban greening.By increasing the coverage of green space, wetlands and forests, the natural water cycle and ecosystem functions will be restored, and the ecological adaptability and resilience of the city will be improved.At the same time, sponge city encourages the use of permeable pavement and biological detention facilities (Figure 2) to reduce the hardening of the city and increase the permeability of the surface, so as to reduce the flood risk and improve the urban heat island effect.The implementation of the concept of sponge city needs the joint efforts of the government, planners, designers and citizens.The government should introduce relevant policies and standards to encourage and support the construction of sponge cities. Planners and designers need to consider the principles and requirements of sponge city in urban planning and design to ensure the sustainable development of the city.Citizens should also actively participate, raise awareness of environmental protection and take actions to reduce the consumption and pollution of urban water resources [4].

Present situation and development of rural tourism landscape construction
Landscape construction of rural tourism destination is an important part of rural tourism development, which is of great significance to enhance the attraction of rural tourism, enhance the tourist experience and promote rural revitalization.At present, the landscape construction of rural tourist destinations has different construction status and development direction in different regions [5].
First of all, the present situation of landscape construction in rural tourist destinations is diverse.In some areas, the landscape construction of rural tourist destinations has achieved good results, and a number of fine scenic spots with local characteristics have emerged.These scenic spots create a unique rural landscape by protecting and restoring traditional buildings, traditional villages and farmland scenery (Figure 3), attracting a large number of tourists.However, there are also some areas where the landscape construction of rural tourist destinations lags behind, lacking overall planning and design, and the image of scenic spots is single, the content is monotonous and unattractive.Secondly, the development direction of rural tourism landscape construction is diversified.In the future, the landscape construction of rural tourist destinations should pay attention to protecting and inheriting rural characteristic culture and promoting local culture and folk customs.By tapping resources such as rural history and culture, folk traditional skills and local specialties, we will create rich and diverse cultural experience projects and provide more attractive and participatory tourism products [6].At the same time, the landscape construction of rural tourist destinations should also pay attention to ecological protection and green development, create ecological agriculture, ecological tourism and ecological leisure scenic spots, and provide healthy and sustainable tourism experience.In addition, rural tourism landscape construction should also focus on innovation and improve service quality.By introducing modern scientific and technological means, such as virtual reality, augmented reality, etc., the interaction and experience of scenic spots are enhanced, and more rich and diverse travel experiences are provided for tourists.At the same time, scenic spots should strengthen the construction of infrastructure and service facilities, improve the reception capacity and service quality of scenic spots, and meet the needs of tourists [7].The present situation of landscape construction in rural tourist destinations is different in different regions, but it shows diversity on the whole.In the future, the landscape construction of rural tourist destinations should pay attention to protecting and inheriting rural characteristic culture, ecological protection and green development, and at the same time innovate and improve the service quality to provide tourists with more diverse tourism experiences [8].

The application of the concept of sponge city in the landscape construction of rural tourist destinations.
The concept of sponge city can be applied to rainwater management, green building, water protection and restoration, wisdom management, community participation and education and publicity in rural tourism landscape construction [9].Reasonable application of the concept of sponge city can improve the sustainability of rural tourism landscape and provide better tourism experience for tourists.

Rainwater Management
The concept of sponge city emphasizes the rational management and utilization of rainwater.In the landscape construction of rural tourist destinations, rainwater collection system can be used to irrigate farmland, landscape greening, fish pond culture and other aspects to improve the utilization efficiency of water resources [10].In addition, landscape facilities such as rain gardens and rain wetlands can be built to improve water quality and provide a better landscape environment by naturally filtering and purifying rain [11].

Green Building
The concept of sponge city advocates green architecture and pays attention to the integration of architecture and natural environment.In the landscape construction of rural tourist destinations, sustainable building materials and technologies can be adopted to build green buildings with rural characteristics.At the same time, by means of roof greening, three-dimensional greening and vertical greening, the vegetation coverage area of the scenic spot will be increased to provide better ecological environment and ornamental value [12].

Water Protection and Restoration
There are usually lakes, rivers, reservoirs and other water bodies in rural tourist destinations, and the concept of sponge city can be applied to the protection and restoration of water bodies.Through the construction of wetlands, river ecological restoration and other projects, the ecological function of water bodies can be restored, the water quality can be purified and the landscape value of water bodies can be increased [13] [14].At the same time, the planning of the ecological landscape around the water body is also very important, and a better tourist experience can be provided by designing a beautiful waterfront landscape (Figure 4).

Wisdom Management
The concept of sponge city emphasizes intelligent management and technical application, and can introduce the technical means of smart city into the landscape construction of rural tourist destinations.Through the construction of intelligent scenic spot management system and information-based tourist guide system, the efficiency of scenic spot management and tourist experience can be improved [15].At the same time, combined with big data analysis and artificial intelligence technology, the tourist behavior and scenic resources are intelligently managed and optimized.

Community Participation and Education Publicity
The concept of sponge city emphasizes community participation and public education.In the landscape construction of rural tourist destinations, community residents can be encouraged to participate in the construction and management of scenic spots, and their sense of belonging and responsibility for scenic spots can be improved.At the same time, by carrying out environmental education and publicity activities, the public's understanding and awareness of the concept of sponge city will be improved, and the development of sustainable tourism will be promoted.
