摘要
以乌梁素海湿地为例,从生态系统健康的内涵出发,构建由组成结构、整体功能和外部环境3个要素的22个指标组成的生态健康评价指标体系,在此基础上采用熵权法,确定指标权重,计算近10年的水生态健康指数,根据国内外相关研究的有关标准,将水生态系统健康评估标准分为很好、好、中等、较差、很差五级,进而对乌梁素海湿地水生态系统健康结果分析。
Take the Wuliangsuhai wetland for example, the paper build the ecological health assessment index system composed of 22 indicators. from the connotation of ecosystem health including the three factors of composition. the overall function and the external environment, then the paper determine the indicators Weight on the base of the entropy method in order to calculat nearly 10 years of aquatic ecological health indieators.aeeording to the relevant domestic and international research standards,which divide the assessment standards of aquatic ecosystem health into very health, health, common, common illness, illness, lastly,the paper analysis the results of the wetland aquatic ecosystem health.
