【摘要】 利用中国图们江流域已有的资料和实地监测数据,建立了以生态特征、服务功能和社会政治环境为项目层包括22个指标的湿地健康评价体系;采用层次分析法和特菲尔法,确定指标权重,根据韦伯—费希纳定律,分别评价中国图们江上游、中游、下游流域和全流域湿地生态系统的健康状况。研究结果表明,中国图们江上游、中游和下游流域湿地生态系统的综合健康指数分别为0.237 3、0.181 6和0.188 3,其健康状况分别为亚健康、轻度退化和轻度退化;整个中国图们江流域湿地生态系统综合健康指数为0.190 1,其健康状况为轻度退化。更多还原

【Abstract】 Based on the existing datas and field monitoring datas in the Tumen River Basin, China, a wetland health evaluation system was established, which contains 3 project layers(ecological characteristics layer,service function layer, and social and political environment layer), with 22 indicators in total. The weights of index were determined by means of the analytic hierarchy process(AHP) and the Teffel methods. The health degrees of the wetland ecosystems in the upper, middle and lower reaches of Tumen River in China as well as the whole basin were evaluated based on Weber-Fischner’s law, respectively. The results showed that the comprehensive health indexes of the ecosystems in the upper, middle and lower reaches of Tumen River in China were 0.237 3, 0.181 6 and 0.188 3, respectively, and their health degrees were sub-health, and mild degradation, mild degradation, respectively. The comprehensive health index of the ecosystem in the whole Tumen River Basin in China was 0.190 1, and the health degree was mild degradation.更多还原
