以生态承载力和可持续发展理论为基础,采用综合分级评价模型,构建了河北省武安市生态承载力评价指标体系,从生态弹性力、资源环境支撑力和生态环境承载压力三方面对武安市生态承载力及其影响因素做出了评价,得知武安市22个乡镇的生态弹性力、资源环境支撑力和生态环境承载压力存在空间分异特征和不平衡性,生态承载力有两极分化的趋势。根据相关性分析,得出生态承载力与人均水资源占有量、植被覆盖度呈显著正相关关系,与水资源开发利用率、工业用地比重呈显著负相关关系,并将22个乡镇分为生态承载力有较大的支撑空间、生态承载力尚有一定的支撑空间、生态承载力极为有限三大类。
以生態承載力和可持續髮展理論為基礎,採用綜閤分級評價模型,構建瞭河北省武安市生態承載力評價指標體繫,從生態彈性力、資源環境支撐力和生態環境承載壓力三方麵對武安市生態承載力及其影響因素做齣瞭評價,得知武安市22箇鄉鎮的生態彈性力、資源環境支撐力和生態環境承載壓力存在空間分異特徵和不平衡性,生態承載力有兩極分化的趨勢。根據相關性分析,得齣生態承載力與人均水資源佔有量、植被覆蓋度呈顯著正相關關繫,與水資源開髮利用率、工業用地比重呈顯著負相關關繫,併將22箇鄉鎮分為生態承載力有較大的支撐空間、生態承載力尚有一定的支撐空間、生態承載力極為有限三大類。

Based on the theories of ecological carrying capacity and sustainable development ,the evaluation index system of ecological carrying capacity in Wu'an City of Hebei Province is established through adopting the comprehensive grading evaluation model ,and evaluate the factors affecting ecological carrying capacity from 3 aspects ,including ecosystem resilience ,anchorage force of resources and environment and pressure of ecosystem .It was also learned that there exists spatial differentiation and imbalance in ecosystem resilience ,anchorage force of resources and environment and pressure of ecosystem of 22 towns in Wu'an City .What's more ,the ecological carrying capacity has a tendency to polarization .According to the correlation analysis ,it was concluded that the correlation between ecological carrying capacity ,per capita water resources ,and vegetation coverage was significantly positive;and water resources development and utilization ,the proportion of industrial land had a significant negative correlation relationship .In addition ,22 towns were divided into three categories :ecological carrying capacity with larger supportive space ,certain supportive space ,and limited supportive space .
