摘　　要：生态经济分区是宏观管理区域社会经济发展的一种新模式，旨在协调区域经济发展与保护环境、利用自然资源的关系，实现区域社会经济的持续发展。从生态经济系统原理出发，选择了５３个适合密云水库集水区生态经济系统分类的特征指标，以乡为分类的基本单元，应用５种聚类分析方法对密云水库集水区（北京）３８个乡（镇）进行了不重叠、内在的等级聚合分类。结果表明：离差平方和法分类效果最好，用此方法将全区划分为５个生态经济区和８个生态经济亚区，取得了符合实际的分区结果。此外，对每一生态经济区的生态经济特点和发展方向进行了具体分析，为建立密云水库集水区最佳生态经济结构提供了科学依据。Eco economical division is a new model for integrated development of social economy, enviroment protection and natural resources utilization within a certain region. According to the eco economic theory, 53 specific indexes suitable for classification of eco economic systems of the Miyun reservoir watershed in Beijing were selected. These specific indexes were taken for classifiying the eco economic systems of 38 townships at Miyun reservoir watershed and 5 methods of non overlapping intrinsic hierarchical agglomerate analysis were adopted. The results indicate that the Ward's hierarchical classification method is better than the others during this classification. The whole region was divided into 5 eco economic regions and 8 sub regions by using this method, and the results was good and objective. In addition, the special causes of eco economic characteristics and development in every eco economic region were analyzed. It provides scientific base for optimizing eco economic system structure at the Miyun reservoir watershed.
