密云水库集水区生态经济分区研究

生态经济分区是宏观管理区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

Eco-economic Division of Miyun Reservoir Watershed in Beijing

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.
