Research on Environmental Carrying Capacity in Jining City Based on Principal Component Analysis

摘要:

该文以济宁市环境承载力为研究对象，运用主成分分析法，从影响环境污染状况、环境治理状况、人口状况、经济发展状况、自然资源状况、物耗能耗状况等19个指标中，提取出影响环境承载力动态变化的3个主成分，对济宁市环境承载力年际变化进行了综合评价。结果表明：2006—2010年，济宁市环境承载力呈现逐年上升的趋势。该研究评价结果较好，可以为该地区的可持续开发规划提供理论参考。

Abstract:

In this paper, regarding environmental carrying capacity in Jining city as the study object, by using principal component analysis, three principal components which will affect the dynamic bearing capacity of environment have been extracted from 19 indicators which will affect environmental pollution, environmental governance, population, economic development, natural resources and energy consumption. Interannual changes of environmental carrying capacity in Jining city has been evaluated comprehensively. It is showed that environmental carrying capacity in Jining city has showed an increasing trend from 2006 to 2010. Evaluation result of this study is good. Thus, it can provide a theoretical basis for sustainable development in this area.
