针对2014青岛世界园艺博览会园区雨水利用体系进行方案设计,将传统的“雨水排放”转变为“雨水生态循环和再利用”,实现区域内雨水自然生态化的综合利用.园区总汇水面积约为5畅10 km 2,预测展会期间(4—10月)在50%和75%保证率下,雨水可利用量分别约为46畅4万 m 3和36畅7万 m 3,主要回用于园区景观水体补充和地下水涵养.雨水利用以绿地自然渗透为主,涵养李村河上游水源地;不能及时入渗的雨水以明渠收集,经生态湿地自然净化后,汇入园区3个天然水库进行调蓄.

Rainwater ecological circulation and reuse will replace traditional stormwater discharge at the site of the Qingdao International Horticultural Exposition 2014 based on the idea of a green and ecological park .The catchment area of the site is about 5.10 km 2 .Utilizable rainwater is about 46.4 ×10 4 m 3 and 36.7 ×10 4 m 3 at guarantee rates of 50% and 75%, respectively, during the exhibition (from April to October), and will mainly be used to supplement landscape water and conserve groundwater at the site .Natural rainwater penetration through green land is the main pattern of rainwater reuse to conserve the water source in the upper reaches of the Licun River.The rest of the rainwater that cannot penetrate in time is collected by channels and purified by ecological wetlands naturally, and finally stored and regulated in three natural reservoirs at the site .
