以山地城市老旧街区雨水径流排泄过程为研究对象,从其特定的环境因子与雨水径流的关联性分析入手,通过分析现状街区内雨水径流排泄特点和存在的问题,并结合与之相关的环境因子特征,阐述了在街区层面基于低冲击理念下的可持续雨水径流调控改造策略,为山地城市街区尺度下的可持续雨洪管理提供新的借鉴与思路.
Taking the old runoff drainage in the mountainous urban area as the research object, this paper starts with the analysis of the correlation between the specific environmental factors and rainfall runoff. By analyzing the characteristics and existing problems of the runoff drainage in the existing neighborhoods and the related environment This paper expounds the strategy of sustainable rainwater runoff regulation based on low impact concept at the street level, and provides a new reference and train of thought for sustainable stormwater management in the urban scale of mountainous cities.
