Land ecological sensitivity evaluation is an important method to analyze the stability of regional land ecological environment,and is the way to coordinate the ecological environment and economic development in the new era.It is of great significance to optimize the structure and layout of land use and promote the coordinated development of ecological environment and economic society.In this paper,Lincheng County is taken as the research area.From the three aspects of natural factors,human factors and land use types,seven land ecological sensitivity factors including slope,aspect,elevation,waters,vegetation coverage,night light index and land use type,are selected to evaluate the land ecological sensitivity of Lincheng County by using GIS technology.The results show that the proportion of high sensitive area,middle sensitive area,low sensitive area and insensitive area in Lincheng County is 13.97%,33.11%,32.48%and 20.44%respectively,and the sensitivity of forest land and land near water area in western mountainous area is higher,showing a decreasing trend from west to east.Low-sensitive and non-sensitive areas are mainly distributed in the eastern plain and hilly areas and are relatively scattered,mainly for residential and industrial land.
