Abstract: Oriented by ecological, production and living functions of land, this paper analyzes the status of land use in Xueshan Township, Luquan County, Yunnan Province using the method of assignment. The land is classified into general production land, production and ecological land, general living land, living and production land, living and ecological land, general ecological land and ecological and production land. The result is compared with the classification system of the second national land survey. In theory, the classification system of ecological land, living land and production land is constructed. Taking Xueshan Township, Luquan County, a typical alpine valley area of Jinsha River as an example, based on the survey data on the changes of land use in Xueshan Township in Luquan County in 2016, this paper analyzes the distribution of ecological land, living land and production land in Xueshan Township. The results show that in Xueshan Township, ecological land (including general ecological land and ecological and production land) has the largest proportion (54.84%) in area, followed by production land (including general production land and production and ecological land) (44.41%), and living land (including general living land and living and production land) has the lowest proportion (only 0.75%). In overall, the distribution of production land and ecological land in Xueshan Township is not reasonable enough. For example, the proportion of dry land with a slope bigger than 15° and serious oil erosion in the township is currently 79.23%, among which, the dry land with a slope bigger than 25° and particularly serious soil erosion accounts for 52.88%. Therefore, it is necessary to gradually take measures to convert cultivated land into forests and further optimize the structure and spatial configuration of ecological land, living land and production land.
