【摘要】 显著的地形与气候特征为重庆城区的雨水径流控制带来严峻挑战,在建设重庆山地海绵城市的背景下,山地公园极具构建低影响开发雨水控制体系的潜力与价值.选取重庆主城区12例典型山地公园作为研究对象,基于汇流基本单元——子汇水区进行径流特征分析,并结合不同子汇水区类型提出具有针对性的山地公园低影响开发雨水控制策略,从山地海绵体的绿色开放空间优化层面实现城市小流域的雨洪管理.更多还原

【Abstract】 The distinct topography and climatic characteristics bring severe challenges to the rainwater runoff control in Chongqing. Under the background of constructing a mountainous sponge city in Chongqing, the mountain parks have great potential and value for the low-impact rainwater control system. In a study reported herein, 12 typical mountain parks in the main urban area of Chongqing were selected as research objects. Combined with different types of sub-catchments, this paper analyzed the runoff characteristics and proposed a low-impact development strategy for optimizing stormwater management in small scale watersheds from the perspective of the mountain green open space.更多还原
