摘　　要：研究湖泊形态健康水平对合理开发利用湖泊资源和管理与保护湖泊生态系统健康均具有重要意义。基于湖泊形态健康的概念,从平面形态特征和形态变化特征两方面选择8个指标构成评价指标体系,确定了湖泊形态健康评价标准,采用改进熵权—集对分析法对江苏省10个典型湖泊的形态健康进行了评价,并将结果与采用层次—集对分析法的评价结果进行了比较。结果表明,该方法合理、可行。The research of lake formation health will be of great importance in rational lake resources utilization, management and protection of lake ecosystem. Based on the concept of lake formation health, 8 indicators are selected to establish evaluation index system in terms of plane morphological characteristics and shape change features. And then the evaluation criterion of lake formation health is determined. Finally, improved entropy weight-set pair analysis method is used to evaluate lake formation health by taking 10 typical lakes in Jiangsu Province for an example. Comparison of hierar- chical-set pair analysis method, the result shows that the proposed method is reasonable and feasible.
