武汉市生态承载力综合评价

Comprehensive Evaluation of Ecological Carrying Capacity in Wuhan City

以武汉市为研究对象,基于P-S-R模型构建指标体系,确定武汉市生态承载力的定量指标,进而构建城市生态承载力评价模型,包括城市生态支持力模型、城市生态压力模型、城市生态承载力模型,利用构建的评价指标体系和模型综合评价了2005-2014年武汉市生态系统承载力状况。结果表明,2005-2014年,武汉市生态承载力综合水平先在一个良好的状态下保持稳定,然后下降到很低的水平,最后有缓慢回升的趋势。其中,2005-2010年,武汉市生态承载力综合水平稳定在一个良好状态;2011-2014年,生态承载力表现为超负荷,随后武汉市积极改变经济发展方式和调整产业结构,生态系统得到一定修复,生态承载力有了回升的趋势。

Taking Wuhan city as the research object, based on the P-S-R（Pressure-State-Response） model, the quantitative indicators of the ecological capacity in Wuhan city was determined,and then the urban ecological carrying capacity evaluation model was build, including urban ecological support model,urban ecological pressure model,urban ecological capacity model.Then the evaluation index system and model were used to evaluate the carrying capacity of ecosystem in Wuhan form 2005 to 2014. The results showed that,from 2005 to 2014,the comprehensive level of ecological carrying capacity of Wuhan was stable in a good state,then dropped to a very low level,and finally had a tendency to rise slowly. From 2005 to 2010,the comprehensive level of ecological carrying capacity of Wuhan was stable in a good condition. From 2011 to 2014,the ecological carrying capacity showed overload,then Wuhan actively changed the mode of economic development and adjusted the industrial structure,the ecological system was fixed,and the ecological carrying capacity had a tendency to rise.
