- Abstract:

Based on 3S technology, research for industry structure and land use/over can not only provide the basis for economic development, but also provide a reference for the ecological and environmental protection. The Jinghe County was selected as an example for the study, and the Landsat images of 2005, 2011 and 2014 were selected as remote sensing data. RS and GIS technology were used to extract land use/cover data of Jinghe County, and near 10 a social-economical data were combined to construct the Driving force-Pressure-State-Impact-Response (D-P-S-I-R) land ecological security evaluation model in Jinghe. Entropy weight method was used to determine the index weights. Then, the land use/cover and land ecological security changes in Jinghe County were analyzed. The results show that:(1) between 2005 and 2014, the deteriorated land ecological security situation had been improved in Jinghe County, the land ecological security distribution pattern was not unequal; (2) the high value of land ecological security index was water body, farmland, and grassland; (3) many areas in Jinghe County are at the critical security level. The land ecological security of Jinghe County needs to be improved urgently.
