| 摘 要： | 以经济发达的宁波市区为例,通过水环境敏感性与水质现状两方面综合评价城市内部空间水环境效应,从中心城区至外围地区,因人口集聚水平、产业发展类型和水污染处理能力的差异,水环境效应指数不断降低;探究其空间异质性,各乡镇评价单元水环境效应指数存在正向相关;运用地理加权回归（GWR）模型,定量分析水环境效应影响机理,其中经济发展水平是水环境演变的基础,产业发展与人口集聚则是造成水环境压力的直接原因。人口空间集聚带来的水污染排放,产生的水环境效应远高于其它因素,是城市内部水环境下一步治理的重点。 |

| Abstract: | With development of urban society and economy, increasing emissions of water pollutants have led to water environment deterioration and restricted city’s sustainable development. In this paper, Ningbo city was selected to evaluate water environmental effects by two aspects on water environmental sensitivity and present water quality. With the differences on the population agglomeration level, type of industry development, water pollution treatment capacity, and the index of water environment effects are decreasing from the city center to the periphery. The method of exploratory spatial data analysis (ESDA) is used to explore the spatial heterogeneity of evaluation units. The geographical weighted regression (GWR) indicated the quantitative analyses on the influence mechanism of water environment effects. Among influencing factors, economic development level was the predominant drivers of urban water environment change. At the meanwhile, industrial development and population agglomeration have been identified as direct causes of water environment pressure. They have significant positive impacts on water environmental effects. Spatial layout and dominant industry types of industrial parks had greater impacts on water environment effects than the other factors, and this presented issues that needed special attention for control water environmental pollution in future. By regulating the industry access threshold and spatial distribution of different development types, the ecological function zoning can effectively prevent negative effects of industry development on urban water environments. The present work can provide scientific basis for deciphering coordinated effects between water environmental protection and urban economic sustainable development, and can promote the improvement of water environment quality. |
