城市绿地隐形蓄水系统的建立及生态功能分析

Ecological function analysis and construction of latent water-accumulation system for urban greenland

城市雨水资源的有效利用是建设节约型社会面临的问题之一。针对目前城市普遍重排水轻蓄水的现状,从提高水资源利用率和构建城市良性生态系统的角度,提出了城市绿地隐形蓄水系统的概念、结构、组成和蓄水原理,分析了隐形蓄水系统在抑制环境污染、利用和节约水资源、改善植物生长条件、促进生物多样性形成和保障水生态安全等方面的生态服务功能。

The efficient utilization of rain resources in urban ecosystem is very important during building economical type of society. According to the fact that peoples pay much attention to drainage but little to water accumulation, this paper put forward the definition, composition, structure and principle of latent water-accumulation system for urban greenland, then, analyzed its ecological service function from aspects such as subduing environment pollution, utilizing and saving water resources,improving plant growth environment, promoting formation of biodiversity and guaranteing the ecological safety of water as well.
