北京市城市综合承载力指数研究——基于主成分分析
发布时间：2018-11-16 18:37
【摘要】：本文首先以自然生态系统的种群承载力为起始点,界定城市综合承载力的内涵。其次根据指标选取原则,对应于承载主体和承载客体分别选取相应的评价指标。最后基于主成分分析法构建城市综合承载力指数评价模型,并测算出北京市综合承载力指数。研究结果表明北京市已经由2009年前的超载状态逐渐转变为富余状态。但也建议北京市要警惕城市承载压力变化带来城市综合承载能力降低的可能。
[Abstract]:In this paper, the population carrying capacity of natural ecosystem is taken as the starting point to define the connotation of urban comprehensive carrying capacity. Secondly, according to the principle of index selection, the corresponding evaluation indexes are selected for the bearing subject and the bearing object respectively. Finally, based on the principal component analysis method, the evaluation model of urban comprehensive bearing capacity index is constructed, and the comprehensive carrying capacity index of Beijing is calculated. The results show that Beijing has gradually changed from the overload state before 2009 to the surplus state. However, it is suggested that Beijing should be on guard against the possibility that the change of urban bearing pressure may lead to the decrease of urban comprehensive bearing capacity.
