在上海辰山植物园“绿环”的堆筑建设及水生专类园的营建技术上,采用雨水花园这种新型节能绿地营造技术,对雨水渗透和滞留以控制雨水径流及控制径流污染为目的,通过功能性植物的合理配置,改变传统雨水管理模式,使园内水资源被重新整理分配,园内地下水得以补充；通过对雨水进行过滤处理,控制水体资源的水质污染,改善了上海辰山植物园的绿地环境、城市水资源调配,并为上海带来了新的绿地景观,为市民提供了游憩环境,更为城市水资源尤其是为雨水资源的利用及管理提供了理论和实践依据.%Rain garden, a new construction technique for energy - saving green belt, is applied to the building of " ring" and A-quatic Plant Garden in Chenshan Botanical Garden of Shanghai. And it performs perfectly in several aspects. Firstly, through retaining and infiltrating the rainwater, and configuring the functional plants appropriately, it replaces the rough traditional rainwater management, which means reallocating the water recourse and supplementing groundwater in garden; secondly, through filtering the rainwater, the rain garden can control water body pollution, which improves the green environment in Chenshan Botanical Garden, and optimizes the reallocation of urban water recourse.
