基于“海绵城市”理念的下沉式绿地优化设计
Optimization Design of Sunken Greenbelt Based on the Concept of“Sponge City”
摘要
Abstract
In many Chinese cities, the conflict of frequent flooding and water shortage got deeper, it is necessary to integrate the latest concept of ecological stormwater management and “sponge city” into the construction of sunken green space landscape, so as to realize multiple benefits including the flooding control, water resource utilization and landscaping. Based on Beijing “Code for design of stormwater management and harvest engineering”, through water balance method, the design parameters of sunken greenbelt is determined. In the loamy sand area, sink rate of green space is 50%, under the condition of the control rate of total annual runoff more than 85%, when the ratio of green space for 20%, 30%, and 40%, the proper sinking depth of sunken greenbelt are 200mm, 120mm, and 75mm, respectively. Final y, the article briefly introduces the optimum design of grading, landscaping, and plant waterlogging time.关键词
