摘要
Abstract
In this paper, eco-environmental vulnerability was studied in grid mode in stead of traditional township mode so as to reflect the unevenness and continuity of regional natural environmental features.In the grid mode, a novel method of “decomposition-synthesis” was established for the first time by combining the “Geographic Information System Technology” and “AHP-Fuzzy Comprehensive Evaluation Model” together to research ecological environmental vulnerability.It turned the original fuzzy matrix with limited data into a huge spatial one containing a lot of grid information, which solved the contradiction between the simplified layers attributes and the principle of maximization of fuzzy membership.The eco-environmental vulnerability was analyzed and evaluated comprehensively from the point view of “fuzzy membership” in this paper.关键词
