【摘要】 利用能值足迹分析方法,对近8年北京城市生态空间承载力进行计算分析,结果表明:(1)北京城市生态空间能值承载力变化稳定,起伏较小;(2)北京城市生态空间能值足迹变化波动大,这主要与废弃物和工业产品的生产有关;(3)从多年平均值来看,北京城市生态空间处于赤字状态。本研究基于复杂系统理论,对城市生态空间的复杂特性进行简单探讨,从生态学的能量流动角度出发,衡量城市生态空间的承载状况,评价结果合理。更多还原

【Abstract】 Using the energy value footprint analysis method,the urban ecological space carrying capacity of Beijing in the recent 8 years is calculated and analyzed. The results show that:(1) Beijing urban ecological space energy carrying capacity changes stably and with less fluctuation;(2) The fluctuation of Beijing urban ecological space energy footprint is large,which is mainly related to the production of waste and industrial products;(3) From the view of the multi-year average,Beijing’s urban ecological space is in a state of deficit. Based on the theory of complex systems,this study briefly discusses the complex characteristics of urban ecological space. From the perspective of ecological energy flow,the measurement of urban ecological space is carried out,and the evaluation results are reasonable.更多还原
