摘要
According to Ecological environment characteristics in area of research and the principle of evaluation index selection, this paper selects soil moisture, the land usage/cover, topography, soil salinization, land pressure and destruction index as influencing factors, and puts each main details of ecological environment evaluation index system as the index layer. Furthermore, the establishes the ecological environment evaluation index system of Changshan salt mine and determines the weight of each evaluation index by using AHP. At the same time, the paper extracts evaluation index information with a combination of visual interpretation and computer automatic extraction, in order to divide area of research into five grades such as excellent, fine, medium, bad and worse, through the use of quantitative grading and standardization of each evaluation index coupled with comprehensive evaluation model.
