南昌市乌沙河沿河景观工程生态设计

Ecological Design of Wusha River Landscape Engineering in Nanchang City

乌沙河是南昌市昌北城一条重要的城市河流,是沿岸城镇的景观生态廊道,又是基础经济发展的摇篮。针对乌沙河沿岸城镇防洪排涝标准低、河水污染严重、沿河生态景观效果差等问题,运用生态学的原理,通过截污利用、生态廊道设计、低影响开发等生态设计方案,对乌沙河治理段进行综合生态设计,合理利用雨污资源,减小初期雨水径流污染,恢复河道生物多样性和生境多样性,打造乌沙河沿岸景观生态廊道,同时,对建设海绵型城市具有一定的参考价值。

Wusha River is an important urtban river in the North area of Nanchang City,which is a landscape ecological corridor of coastal town and the cradle of basic economic development.In allusion of the low of flood control and drainage,water pollution,poor effect of ecological landscape,based on the ecological principles,this paper puts forward the principles of ecological design through eco-design method,such as interception use,ecological corridor and low-impact development.The comprehensive ecological design was adopted to treat the Wusha River.The rain and sewage resources was utilized to reduce rainwater runoff pollution in initial stage and restore biodiversity and habitat diversity for building landscape ecological corridor of the Wusha River.The research has certain reference value for construction of sponge city.
