摘　　要：文章以杭州城市中心区5条内河为研究对象,选取内河两侧300米范围内与水质关系最为密切的城市道路与绿地两类用地,建立表征数量结构和布局结构的土地利用格局指数以及相关的水质指数,运用SPSS分析土地利用指标与水质指标之间的相关关系并建立回归分析模型,揭示城市土地利用对内河水质的影响机理与关键机制。结论为:城市道路和绿地两种土地利用类型对内河水质产生了截然不同的影响,多项绿地指标的改善能有效削减道路指标所产生的消极影响;有必要在城市规划编制和管控中,通过完善道路交通结构、改进雨水排放模式、合理设置绿带宽度等综合措施,控制和管理面源污染,改善城市内河水质。Taking the five inland rivers in the Hangzhou city center as the research object and choo- sing urban roads and green space closely related to the water quality within the range of 300 meters on both sides of the inland rivers, this paper establishes land-use pattern index characterizing the quantity structure and the layout structure, and the related water quality index, analyzes the rela- tionship between land-use index and water quality index by SPSS and establishes the regression anal- ysis model and reveals the influential theory and key mechanism of urban land-use on inland rivers water quality. It concludes that the two kinds of land use types, urban road and green space, have distinct influence on the water quality of inland river, and the improvement of a number of green in- dex can effectively reduce negative effects produced by the road index. It is necessary to control and manage non-point source pollution, and improve urban inland river water quality through some com- prehensive measures of perfecting road traffic structure, improving drainage patterns, enhancing the green space connectivity, and setting reasonably green belt width and so on in the urban planning or- ganization and management.
