摘要
在海绵城市建设背景下,山地公园越来越多地被赋予生态海绵的功能。山地公园水环境优化不仅有助于解决其自身的雨洪问题,而且能够涵养水源、保持水土、降低城市洪涝风险,充分发挥海绵效应。以海绵城市建设理念为引导,基于山地公园的水文特征研究与水文过程分析,提出分区、分级设计策略以及从源头到末端的水环境优化方法,并以南京市官窑山、李家山公园为例探讨该方法的应用实践。设计后的水文模拟结果显示:该方法能够较好地满足海绵城市建设标准,削峰延时的同时促进了雨水入渗和利用。通过本研究以期对城市建成区类似尺度的山地公园水环境优化设计有所助益。
Under the backdrop of low impact development and sponge city construction, more and more mountain parks have been endowed with the function of ecological sponge. The water environment optimization is not only helpful when solving its own stormwater problems, but also to conserve water resources, preserve water and soil, and reduce the risk of urban flood. Guided by the concept of Sponge City and based on the hydrological characteristics of mountain parks and the hydrological process analysis, this study puts forward the strategies of zoning and grading regulation from the source to the end for rainwater control and utilization in mountain parks water environment optimization design. Taking Guanyao and Lijia Mountain Parks in Nanjing City as examples, it discusses practical applications of water environment optimization design methods. The hydrological simulation results show that it can better meet the construction standards of sponge cities, delay the confluence rate and time, promote the infiltration and utilization of rainwater, and help to optimize the design of water environment for mountain parks of similar scale in urban built-up areas.
