基于城市环境特征的低影响开发技术规划策略研究——以海南国际旅游岛先行试验区为例

Planning Strategy of Low-impact Development Technology Based on Urban Characteristics: A Case Study of Hainan International Experimental Tourism Zone Resort

低影响开发技术是在新型城镇化发展背景下实现雨水综合管理、建设海绵城市的重要途径。目前,低影响开发技术纳入城市规划体系时的针对性不强。通过分析气候、地形、下垫面结构、土壤等对低影响开发技术应用产生影响的主要因素,阐述了各类低影响开发技术在不同环境特征下的应用要点。借助海南国际旅游岛先行试验区的规划案例进行论证,探析如何通过技术措施的配置,发挥低影响开发技术在城市排水防涝和环境改善中的效用,以期为该技术措施的规划布局提供一定的参考。

Under the background of new urbanization,low-impact development technology is an important way to achieve comprehensive management of rainwater and transform into a sponge city.At present,low-impact development technology infrastructure is untargeted in urban planning.This paper analyzes main influential factors on low-impact development technology infrastructure,including climate,terrain,and underlying ground structures,and expounds key points on how various techniques have been used under different urban characteristics.Storm system of Hainan International Experimental Tourism Zone is used as a case study,to illustrate how low-impact development technology can work on urban drainage system and environment improvement by configuring technical measures,in order to provide references for the layout of low-impact development technology infrastructure.
