湖泊健康综合评价指标体系研究

Research on the Synthesis Appraisal Index System of Lake Health

[目的]对湖泊健康状况进行综合评价。[方法]在深入挖掘"健康湖泊"内涵的基础上,运用模糊综合评价法构建出评价指标体系,并采用基于专家评分法的层次分析法确定权重值,选取吴江市3个典型的省保湖泊(三白荡、北麻漾、桥北荡)进行综合评价,并对其开发利用保护的模式提出了合理的建议。[结果]湖泊健康状况综合评价结果表明,三白荡、北麻漾均处于基本健康状态,桥北荡处于亚健康状态。该指标体系和评价方法在东部平原河网地区有较强的适用性。[结论]该研究为湖泊的开发利用和保护修复提供了理论依据。

[Objective] The study aimed at assessing the state of lake health.[Method] Based on the concept of ＂healthy lakes＂,the fuzzy integrated evaluation was used to establish the evaluation index system of lake health,and the analytic hierarchy process（AHP） combined with expert evaluation method was used to determine the weight of each indicator.Afterwards,the health state of three typical lakes（Sanbaidang,Beimayang and Qiaobeidang） in Wujiang City were evaluated by the system,and the measures to develop and protect the lakes were put forward finally.[Result] The assessment results showed that Sanbaidang and Beimayang were in basic health,while Qiaobeidang was in sub-health.The indicator system and assessment method are suitable for the rivers in eastern plains of China.[Conclusion] The research could provide scientific references for the development,protection and restoration of lakes.
