城市生态承载力研究进展

Research progress of urban ecological carrying capacity

城市生态承载力是衡量城市生态可持续发展能力的重要标准。通过生态承载力概念的起源发展及其内涵及特点的介绍,总结了生态足迹法、系统动力学法、综合指标评价法等常用的评价方法以及各自的优缺点。指出目前城市生态承载力研究中的不足之处,今后应在理论定义研究、阈值指示意义研究、模型创新、动态预测预警、人居要素研究、政策落实等方面加深和拓展,形成一整套的理论方法体系,以便成果能落实到城市生态建设上。

Urban ecological carrying capacity is an important standard to measure urban ecological sustainable development capacity.Through the origin and development of the concept of ecological carrying capacity as well as the connotation and characteristics of urban ecological carrying capacity.The commonly used evaluation methods are summarized,including ecological footprint method,systematic dynamics method and comprehensive index evaluation method.The advantages and disadvantages of each method are pointed out.At the end of the paper,the shortcomings in current study of urban ecological carrying capacity are put forward,we should do the in-depth research in the future in following aspects:theoretical definition,referential meaning of threshold value,model innovation,dynamic forecasting warning,habitat factors,policy implementation,etc.The goal of future research is to form a whole set of theoretical and methodological system,so that the results can be implemented to urban ecological construction.
