【摘要】 根据城市生态系统承载力理论,以山东省济南市为研究对象,从维持城市生态系统健康、稳定、持续发展的角度,提出济南市城市生态承载力定量指标,构建了城市生态承载力评价模型,包括城市生态支撑力模型、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评价了济南市2004—2008年城市生态系统承载力状况,并分析其变化规律,可为区域可持续发展和环境保护提供科学依据和理论支持。更多还原

【Abstract】 We present quantitative parameters for urban ecosystem carrying capacity of Jinan with the theory of city ecosystem carrying capacity and Jinan as a subject from the perspective of maintaining the health of a city ecosystem,its stability and sustainable development.We also construct an urban ecological supporting force model,an urban ecological pressure model and an urban ecological carrying capacity model.We then apply the evaluation index system and model to the evaluation for Jinan city ecosystem carrying capacity from 2004 to 2008,and analyze its changing law.These can provide a scientific basis and theoretical support for sustainable area development and environmental protection.更多还原
