基于低影响开发的寒地高密度住区空间布局模拟优化研究

Spatial Organization Simulation And Optimization of High-Density Residential in Cold Region Based on Low Impact Development

梳理国内外低影响开发(LID)理念的发展及应用,选取哈尔滨市辰能溪树庭院作为寒地住区典型案例,通过调研分析研究区域特征建立SWMM模型,设计重现期为0.5、3、5、10、50年的降雨情景,对比分析LID空间布局优化方案的径流削减效果。提出寒地住区LID优化策略,以期对我国未来寒地住区LID的发展提供有价值的建议与参考。

Revealing the development and application of the low impact development（LID） at home and abroad. Selecting the Chen Neng Creek Green in Harbin as a typical case of high-density residential in cold region, the SWMM model was established by analyzing the characteristics of the study area, and the rainfall reappearing periods of 0.5, 3, 5, 10 and 50 years were designed. Comparing and analyzing runoff reduction effect of LID spatial organization scheme. This paper summarizes the research and puts forward the optimization strategy of LID in cold region. In order to provide valuable suggestions and references to our countrys cold residential LID development in the future.
