摘要

摘要: 《中华人民共和国长江保护法》要求流域产业结构和布局应与流域资源环境承载能力相适应。从社会、环境、经济、资源和生态5个方面出发，采用DPSIR模型，构建了芜湖市水生态承载力评价指标体系，通过熵权法和分级量化方法对芜湖市水生态承载力进行评价。结果表明：2011—2018年，芜湖市及各区县水生态承载力总体呈上升趋势，市区和繁昌区承载力相对较好，无为市、南陵县和湾沚区呈基本可承载；对芜湖市水生态承载力影响较大的指标为万元GDP用水量、人均水资源量、工业废水排放量、生态环境用水量等；基于各区县的差异，市区需要优化供水结构，繁昌区需要增加生态用水量的投入，无为市、湾沚区和南陵县要进一步提高污水收集处理率。

Abstract: The Yangtze River Protection Law requires that the industrial structure and layout in the river basin should be adapted to the carrying capacity of resources and environment. From the five aspects of society, environment, economy, resources and ecology, the DPSIR model was used to build the evaluation index system of water ecological carrying capacity in Wuhu City, and the entropy weight method and hierarchical quantitative method were used to evaluate the water ecological carrying capacity in the city. The results showed that: from 2011 to 2018, the water ecological carrying capacity of Wuhu City and its districts and counties showed an overall upward trend, the carrying capacity of urban area and Fanchang district was relatively good, while that of Wuwei City, Nanling County and Wanji district was basically bearable. The indicators that had a great impact on the water ecological carrying capacity of Wuhu City were the water consumption of ten thousand yuan GDP, water resources per capita, industrial wastewater discharge, environmental water consumption, etc. Based on the differences among districts and counties, the urban area needed to optimize the water supply structure, Fanchang district needed to increase the input of ecological water consumption, and Wuwei City, Wanji district and Nanling County were required to further improve the sewage collection and treatment rate.
