ABSTRACT

In order to understand the main mineral nutrients content and characteristics of the volcanic lava landforms in Wudalianchi, and to explore the effects of bryophytes on the accumulation of soil nutrients, six volcanoes in different ages were selected, and the habitat distribution, coverage and soil nutrient content of the mosses were investigated. The results were as follows: (1) the species of moss under the old volcanic broad-leaved forest in the Western Jiao Debo mountain, the supine tiger mountain, the nagaruoan mountain and the Maobu Shan mountain were <1%, and the moss of the old volcanic stone pond were more abundant and the coverage was 10% to 15%, mainly distributed in the spyophytes such as the Maojian purple calyx moss, the moss, and the sphagnum, seam moss and leaf fissidens etc. (2) the dominant species in the Xingan Larix forest of the old black mountain in the new period volcano is the dominant species of the sphagnum. The coverage is 50% - 80%. The common species include moss, Ye Xiaoyu, moss and Maojian. The sand and mosses are dominant species in the habitats of the old black hills. The coverage is up to 45%. The associated species are vertical branches, mosses, mosses, and haired moss. (3) the mosses distributed on the fire mountain in the new volcano are mainly dry stone mosses, such as Maojian purple calyx moss, sphagnum, moss, and so on. The coverage is about 10%. There are three petal moss, Maojian moss and juniper moss in the cliffs and sew.
