摘要
该文论述了湖泊生态系统健康概念的内涵及发展,并在此基础上详细介绍了湖泊生态系统健康综合评价的具体内容——指标体系的构建、指标权重的计算、健康分级标准的确定以及综合评价模型的构建等4个方面。对比分析了湖泊生态系统健康评价与安全评价的区别与联系,认为前者是后者的基础,后者是前者向人类社会可持续发展方面的深入研究。剖析了目前湖泊生态系统健康评价中存在的不足,主要包括理论概念及标准的不明确、数据收集不完备、目的性不强等,同时针对湖泊管理以及与其他研究热点问题的结合研究等方面提出了展望。
Based on reviewing the connotation and concept definition of lake ecosystem health,the methods for lake ecosystem health assessment were discussed,including index system construction,index weight calculation,standards for ecosystem health classification and establishment of assessment model.The relations and differences between lake ecosystem health assessment and ecological security evaluation were also analyzed,and it was found that ecosystem health assessment is the basis of ecological security evaluation and the latter is the further research in sustainable development.In addition,the limitations of current methods for assessing lake ecosystem health were addressed,and it was found that concepts and standards are ambiguous,the collected data is incomplete,and the goal of the study is not straight enough.Further research for lake management and the combination of lake ecosystem health and other research focus were proposed.
