基于生态威胁的湖泊生态安全指标体系研究
Study on the Index System of Lake Ecological Security Based on Ecological Threats
摘要
Abstract
Based on the analysis of different levels of ecological security definitions, the lake ecological security was identified by reverse thinking as the lake kept sustainable development under various ecological threats and its form of embodying was each index changes dynamically within the range of sustainable development. The theory and model of lake ecological threats were proposed and Delphi method was applied to divide the characteristics of lake ecological threats into eutrophication, lake shrinkage and water pollution. On this basis, by the methods of analytical hierarchy process and principle component analysis, the lake ecological security index system involving 35 indexes were assessed so as to construct lake ecological security indicator system.关键词
