【摘要】：从"压力—状态—响应"模型(PSR)的作用机制出发,构建包括系统压力、状态、响应3个子系统26项指标的环境承载力评价指标体系,运用熵值法赋权,结合模糊综合评价模型对武汉城市圈环境承载力进行实证分析。研究得出以下主要结论:(1)近年来各城市以及城市之间环境承载力变化较明显,整个武汉城市圈环境状况从西北部向东南部地区逐渐递减;(2)武汉和孝感市环境状况有所改善,环境承载力逐渐增强,黄石、鄂州两地环境状况不断恶化,环境承载力逐渐下降,其他地区环境承载力变化相对较小;(3)依据评价结果,建议武汉城市圈要继续加大环境治理力度,尤其是要改善大气环境质量,加强生态文明建设,提高废水、固体废弃物利用效率和处理率。
[Abstract]:Based on the action mechanism of "pressure-state-response" model (PSR), an environmental carrying capacity evaluation index system, which includes 26 indexes of system pressure, state and response, is constructed and weighted by entropy method. Combined with fuzzy comprehensive evaluation model, this paper makes an empirical analysis on the environmental carrying capacity of Wuhan urban circle. The main conclusions are as follows: (1) in recent years, the environmental carrying capacity of cities and cities has changed obviously, and the environmental status of the whole Wuhan urban circle has gradually decreased from the northwest to the southeast; (2) the environmental conditions of Wuhan and Xiaogan have been improved. The environmental carrying capacity of Huangshi and Ezhou is deteriorating, the environmental carrying capacity is decreasing gradually, and the change of environmental carrying capacity in other areas is relatively small. (3) according to the evaluation results, It is suggested that Wuhan urban circle should continue to strengthen environmental control, especially to improve the quality of atmospheric environment, strengthen the construction of ecological civilization, improve the utilization efficiency and disposal rate of wastewater and solid waste.
