北京跨界水源地生态可持续发展模式比较研究——以官厅水库流域延庆怀来两县为例

水资源短缺和水环境污染的现状使得北京跨界水源地发展模式受到各界的关注。以官厅水库流域的北京市延庆县和河北省怀来县为例，运用指标体系进行对比分析，得出了延庆县符合生态可持续的发展模式，其生态可持续发展水平也接近或达到相关标准；而相对而言，怀来县的发展模式和发展现状距离生态可持续的目标差距较大。而行政区划是导致北京跨界水源地境内外发展模式不同的重要原因。

Comparative Studies on Ecological Sustainable Development Model of the Cross-border Water Source Area of Beijing City ---Taking Yanqing and Huailai County of Guanting Reservoir Basin as an Example

The shortage of water resources and polluted situation of water environment maae the development model of the cross-border water source area of Beijing city got more and more attention. Taking Yanqing county and Huailai county of Guanting reservoir basin as an example, this paper used a series of index system for a comparative analysis. It concluded that yanqing＇s development model coincided with the ecological sustainable model and its level was very close to the standard. Comparative speaking, the current model and developing level of Huailai county has a very great distance to the ecological sustainable goal. Administrative division was the reason that the cross-border counties chose different developing model in the water source area of Beijing city.
