Abstract: Plateau lakes are important water sources for production and living conditions, maintaining the development of local economy and society, which play an irreplaceable role in regulating climate and beautifying the environment. Due to the promotion of urbanization and the development of tourism industry, the spatial pattern of lake basins has changed, and the pollution of plateau lakes has intensified. In this paper, Fuxian Lake Basin was taken as the research object. Based on the three remote sensing images from 2005 to 2015, GIS spatial analysis technology and mathematical statistics method, the temporal and spatial change characteristics of land use in the past 10 years were analyzed from three aspects: land conversion amplitude, conversion type and dynamic degree. The results showed that: (1) the lake water, forest lands, dry land, paddy field and grassland were the main land use types in Fuxian Lake Basin, the area of paddy field, forest, construction land increased, the dry land, grassland and shrub land decreased. The garden plot, lake water, and the unused land increased at first and then decreased, the pits and ponds of the reservoir decreased at first and then increased; (2) The land conversion types were mainly the transfer from agricultural land to construction land, the internal transfer of cultivated land, and the transfer from cultivated land to forest land; (3) From 2005 to 2015, there was a big difference in land use dynamics between different periods, land types and regions. During 2010-2015, the change was more severe than the previous five years. The other construction land had the highest dynamic degree, and the lake water surface had the lowest dynamic degree. The regions with higher dynamic degree were distributed in the northern shore of the lake and the central part of the western bank, while the dynamic degree on the northern and western margins of the basin were lower. The research results can provide theoretical reference for the ecological environment protection and the sustainable utilization of land resources in this basin.
