聚类分析在江汉湖群典型湖泊分类中的应用

江汉湖群中的许多通江湖泊由于自然和人为原因失去了与长江及其支流的天然联系，对湖泊生态和湖区经济可持续发展造成了不利影响，重建江湖联系对湖泊生态环境改善和湖区经济发展意义重大。根据4项选择标准，选取江汉湖群中13个典型湖泊作为研究对象，以有关社会经济、生态等方面的调查统计数据为基础，利用聚类分析的方法对江汉湖群中的13个阻隔湖泊进行分类。根据所挑选的16个指标将这些湖泊划分为4大类，并对各类湖泊特点进行了分析，确定了这些湖泊的通江顺序。

APPLICATION OF CLUSTER ANALYSIS IN THE CLASSIFICATION OF JIANGHAN LAKE GROUP

Many lakes in Jianghan Plain have lost their natural links with the Yangtze River and its branches because of natural factors and human activities,causing adverse effects on the ecological environment and the sustainable economical development in the lake region.It is considered that rebuilding the link between the lakes and the rivers is very important,and 13 lakes of the Jianghan Lake Group were selected for the present study.According to statistical data about the social,economic and ecological status,these lakes were analyzed by using hierarchical cluster analysis.Based on the selected 16 impact indexes,the lakes were classified into four types and the characteristics of every type were analyzed,and the order to restoring the relation of these lakes to the Yangtze or Hanjiang Rivers was established at last.
