摘要
城市道路降雨径流污染日益加重,其中一个重要的原因在于城市街区土地利用过程中道路交通布局结构的不合理。文章基于杭州市地形图和谷歌地图,解译得出杭州4个典型街区的道路交通布局结构指数,并通过实验的方法同步得到4个街区的水质指数;运用SPSS和Matlab软件,分析降雨径流污染及其与街区道路交通布局结构的相关性。结论为:交通性路网是造成城市道路径流污染的主要原因;非交通性路网密度的增加及公共交通环境的改善能够引导优化居民出行方式,有效抑制个体机动化出行,避免道路雨水径流水质的持续恶化。最后,提出面向径流水质优化的城市街区道路交通布局结构建议。
Urban road runoff pollution has been a rising problem, for which the unreasonable road traffic layout structure in the process of urban land-use has been one of the most important reasons. This paper interpreted the road traffic layout structure index of 4 typical blocks in Hangzhou based on the topographic map and Google Earth images, and measured the water quality index of the 4 blocks. It analyzed the relationship between traffic layout structure of urban road and runoff pollution using SPSS statistical analysis software and Matlab, so as to reveal the mechanism on the impacts of road traffic layout structure to rainfall runoff water quality and finally proposed some strategies and recommendations to optimize urban road traffic layout structure.
