摘要
在建立北京山区生态评价体系的基础上,参考有关资料和北京的实际状况确定山区生态系统稳定性评价的标准和分级,选择适当的方法确定评价因子的层次关系和重要度,建立了综合评价模型。并以北京山区的一典型区为例对评价模型进行检验,结果与实际基本相符。
On the basis of the ecological evaluation system for mountainous regions of Beijing, the criteria and grades were defined for evaluating stability of the mountain ecosystem with reference to relevant materials and the reality of Beijing. Proper methods were chosen to determine hierarchical relations and importance of the evaluating factors. And on such a basis a model for comprehensive evaluation was erected, and tested on a typical mountainous region of Beijing. The results basically conformed to the reality.
