The evaluation area of Qinghai area of Kunlun Mountain National Park is located on the northern slope of the Kunlun Mountains in Qinghai Province, China. Due to its steep terrain and harsh natural environment, the area is sparsely populated and is one of the most complete and authentic mountainous ecosystems in China. In order to comprehensively grasp the vegetation types, distribution, and survival in the evaluation area, this study used the method of sample plot survey to set up 168 quadrats in the evaluation area of Qinghai area of Kunlun Mountain National Park, recording species composition, quantitative characteristics, habitat information, and referring to the classification of vegetation types and naming in the "Vegegraphy of China", etc. The results show that: (1) There are a total of 384 species of seed plants in 46 families, 146 genera, in the evaluation area, mainly Poaceae, Asteraceae, Fabaceae, and Amaranthaceae. (2) The vegetation in the assessment area can be divided into 7 vegetation type groups, 11 vegetation types, 17 vegetation subtypes, and 36 formations, mainly including Stipa purpurea grassland, Carex parvula meadow, and Oreosalsola abrotanoides desert. Overall, the plant diversity in the assessment area is low, and the vegetation exhibits uniqueness and transitional characteristics; the vertical vegetation zonation along the altitudinal gradient is incomplete, mainly composed of mountainous desert zone, alpine grassland zone, alpine meadow zone, and sparse alpine vegetation zone; The horizontal distribution gradually transitions from grassland vegetation to desert vegetation from east to west and from south to north. The research results provide basic data for the creation and vegetation protection of the Qinghai area of Kunlun Mountain National Park. [ABSTRACT FROM AUTHOR] |
