基于雨水管理的校园景观设计探究——以苏州大学独墅湖校区二期景观改造为例

Study on Campus Landscape Design Based on Rainwater Management—A Case Study of Dushu Lake Campus Second Landscape Transformation of Soochow University

水体本身有一定的自净能力,即经过水体的物理、化学与生物作用,使水中污染物的浓度降低。近年来,水体污染与水体资源的缺乏问题日趋严重。针对苏州大学独墅湖校区二期护校河水体质量较差,多雨季节校园雨水径流严重、大量雨水浪费等问题,提出对校园二期水资源一体化管理理念。一方面,充分利用基地内大片湿地的有利条件,将二期护校河水引入校园内部,经物理性过滤、一次沉降、二次沉降、湿地净化等工序改善护校河水体质量。另一方面,借助苏州年均雨量充沛的自然条件,对校园屋顶、硬质地面、停车场等处进行雨水资源收集和有效利用。同时结合景观设计的手法,对苏州大学独墅湖校区二期水资源一体化管理进行一次有益的尝试,达到改善护校河水体质量,有效提高校园内水体资源利用率的目的,同时营造出集生态、美学、娱乐与教育功能为一体的校园环境。

Water has the self-purification capacity,which is to reduce the concentration of pollutants in water after the physical,chemical and biological processes. In recent years,the problems of water pollution and lacking of water resource are getting worse and worse. Water resource management is proposed based on the problems of Dushu Lake of Suzhou University,such as poor quality,most stormwater runoff in rainy season and waste of rain water. On the one hand,the wetlands should be taken advantage and connect the outside water with the inside water,then improve the quality of water by physical filtration,first settlement,secondary settlement and wetlands. On the other hand,collecting rainwater by the proof of architecture,hard ground and parking lot because of the sufficient rainfall of Suzhou. Besides,trying to combine the water resource management in Suzhou University Dushu Lake Campus with landscape design,aiming to improve the quality of school water and using the water in a more effective way,as well as creating a ecological,beautiful,entertainment and educational campus environment.
