Abstract: Evaluation of land ecological security provides scientific bases for land optimal allocation, making land use planning and environment management. Apengjiang Town was taken as the study area and a system of evaluation of land ecological security has been established consisting of five indices (vegetation, land carrying capacity, values of land use of ecosystem services, ecological risk and slope farmland). Based on optimal combination weight method, the comprehensive scores were determined and calculated for land ecological security. Classification and evaluation of land ecological security of thirteen villages of Apengjiang Town were then carried out according to weighted sum method. The results show that, the security status of Qinlin Village, Xishui Village, Qinggang Village, Huanglian Village, Shihe Village, Pengjia Village and Qituo Village were classified as “good level”, while the other six villages were labeled “sensitive level”. The level of land ecological security depends greatly on quantity, structure and spatial distribution of land use patterns.
