梁滩河生态系统健康评价研究

Study on ecosystem health assessment of Liangtan river

通过收集梁滩河流域的生态、经济和社会状况资料,并利用遥感解译技术,分析影响河流生态系统健康的因素,采用指标体系分析法和专家咨询法,确立梁滩河生态系统健康评价指标体系和评价标准,计算得出评价指标权重,并对河流生态健康状况进行了评价。结果表明:梁滩河上、中、下游生态系统分别处于"亚健康"、"不健康"和"亚健康"级别。该研究结论将为重庆市正在开展的梁滩河保护规划和治理工作提供科学依据。

Based on information on ecology and socio-economics over the Liangtan River,as also as through remote-sensing images synthetical interpretation,it analyzed factors influencing ecosystem health,using index system method and expert score sheet,developed index weighting scheme of ecosystem health assessment,and evaluated ecosystem health in this river.It found that the ecosystems of the upper reaches of Liangtan River were sub-healthy,those of the middle reaches were unhealthy,and those of the lower reaches were sub-healthy.The resulting data provided scientific basis for the Liangtan River protection plan and training in Chongqing.
