The purposes of this research are to preliminarily probe the technology of delimiting the ecological red line so as to provide a reference for protecting ecological environment and rational utilization of land resources.Method of the minimum cumulative resistance( MCR) model,Malthusian prediction models and comprehensive analysis were employed to predict PLE land area and delimit nature reserve of ecological red line. The results indicate that: 1) Cultivated land that is demanded for food security in region,living land area that is demanded by economic and social development,and the land area that has ecological function account for 7. 4% 、3. 05% and 89. 55% of the research region,respectively. 2) nature reserves that have been delimited with ecological red line account for 16. 45% of research region; they mainly distribute in northeastern and northwestern Ejin Horo Banner. The grassland and forestland are the main land use types. 3) It is concluded that Ejin Horo Banner is an area where the ecological sensitivity is higher. Therefore,delimiting ecological red line is practically needed and can enhance people's consciousness of protecting ecological environment in future with the development of society and economic.
