海绵校园景观水体生态设计案例分析

Case study on landscape water ecological design of sponge campus

基于海绵城市的设计理念,以江苏某高校水环境为案例,进行海绵校园景观水体生态设计.首先收集校园屋面、场地、道路雨水,回用于景观水体,通过计算收集水量满足景观水体的水源与水量要求.其次,根据该案例地形特征、水质参数进行水体底部和驳岸的结构设计,主要采用防水层、砾石层等五层水体底部结构和自然草坡与有机材料结合的生态驳岸,达到保证水量与净化水质的目的.为了进一步持续净化水质与满足水体的生态美观,对校园所在城市适合各种水生植物进行了分析,最终完成了驳岸区及上方和浅水区进行植物设计,从而打造生态、天然、丰富、美观的校园景观水体.

Based on the design concept of sponge city,taking the water environment of a university in Jiangsu as an example,the landscape water body ecological design of sponge campus is carried out.Firstly,the rainwater from the campus roof,site and road is collected and reused for the landscape water body.The collected water volume is calculated to meet the water source and water volume requirements of the landscape water body.Secondly,according to the topographic characteristics and water quality parameters of the case,the structural design of the water bottom and revetment is carried out.The five layer water bottom structure such as waterproof layer and gravel layer and the ecological revetment combined with natural grass slope and organic materials are mainly used to ensure the water volume and purify the water quality.In order to further continuously purify the water quality and meet the ecological beauty of the water body,this paper analyzes the suitability of various aquatic plants in the city where the campus is located,and finally completes the plant design in the revetment area and the upper and shallow water areas,so as to create an ecological,natural,rich and beautiful campus landscape water body.
