| 中文摘要: |
| 在北京山区沟域生态承载力内涵的基础上，从实现沟域经济社会可持续发展及经济与环境协调发展的角度，在生态弹性指数、资源环境承载指数、资源环境压力度等方面构建了北京山区沟域生态承载力评价指标体系，并应用综合评价法构建了评价模型。研究结果表明，2010年蒲洼沟域生态弹性指数得分为72.8，属较稳定水平；资源与环境承载力得分为47，属中等水平；资源环境承压度得分为86.5，处于高压水平；生态承载力得分为65.1，属2 级水平。同时依据评价结果，提出了推动蒲洼沟域可持续健康发展的对策建议。 |
| 英文摘要: |
| On the basis of the ecological carrying capacity connotation and to realize the coordinated development of economics and
environment in Beijing mountainous valley areas, the comprehensive evaluation index system was built including ecosystem elasticity level,bearing capacity index and stress index of ecotourism. The comprehensive evaluation method was constructed. The score of ecosystem resilience of Puwa valley region in 2010 was 72.8 which was stable. The score of carrying capacity of resource and environment was 47 which reached medium level. The score of carrying capacity pressure was 86.5 which attained high pressure. The score of carrying capacity system was 65.1 which was secondary level. At last, this study promoted corresponding advices. |
