【摘要】：从经济环境、社会环境和生态环境三个方面选取19个指标构建环境承载力评价指标体系,运用灰色关联TOPSIS法分析了2000~2013年武汉市环境承载力状况,并利用障碍度对影响环境承载力的障碍因子进行诊断。结果表明:(1)总体来看,2000~2013年武汉市环境承载力总体水平不断上升,综合指数从0.3099增加到0.5494;(2)从分项指标来看,经济环境承载力、社会环境承载力和生态环境承载力均呈不同幅度上升趋势;(3)长远来看,经济环境承载力是影响武汉市环境承载力的首要因素,研究期内经济环境承载力和社会环境承载力的障碍度分别以年均0.45%和2.26%的速度增加,而生态环境承载力的障碍度则以年均11.66%的速度下降;(4)影响武汉市环境承载力的主要障碍因子包括人均社会固定资产投资、人均GDP、人均社会消费品零售总额等。
[Abstract]:From the three aspects of economic environment, social environment and ecological environment, 19 indexes are selected to construct the evaluation index system of environmental carrying capacity. The environmental carrying capacity of Wuhan City from 2000 to 2013 is analyzed by using the grey relational TOPSIS method. The obstacle factors affecting the environmental carrying capacity are diagnosed by the degree of obstacle. The results show that: (1) the overall level of environmental carrying capacity of Wuhan City from 2000 to 2013 is rising, and the comprehensive index is increased from 0.3099 to 0.5494; (2) from the sub-index, the economic and environmental carrying capacity, The social environmental carrying capacity and the ecological environmental carrying capacity are increasing in different ranges. (3) in the long run, the economic environmental carrying capacity is the primary factor affecting the environmental carrying capacity in Wuhan. The obstacle degree of economic environmental carrying capacity and social environmental carrying capacity increased at an average annual rate of 0.45% and 2.26% respectively during the study period. However, the obstacle degree of ecological environmental carrying capacity decreased at an average annual rate of 11.66%. (4) the main obstacle factors affecting environmental carrying capacity in Wuhan included per capita investment in fixed assets, GDP per capita, total retail sales of consumer goods per capita and so on.
