摘　　要：随着城市快速发展,基础设施增加,盐城市射阳县的自然资源特别是水资源受到了压力。废水排放量的增加、非点源污染和河岸植被的丧失导致水资源缩减,在雨水系统中使用绿道来保护生态凸显其重要作用。示范河流是排水约16 km2的二级城市河流,该流域正在迅速发展为商业、工业、多户和单户住宅区。在示范的初始阶段,将环境科学与工程结合起来,对河流进行了评估,包括评估河流中的栖息地、生物多样性、树木和土地利用变化以及水文/地貌条件,以分析河流提供的生态服务。With the city's efforts to develop the infrastructure needed for rapid growth,the natural resources,especially water resources,of Sheyang County,Yancheng City are under pressure.The increase of wastewater discharge,non-point source pollution and the loss of riparian vegetation lead to the degradation of water resources.It is of great significance to protect ecological services through the use of greenways in rainwater systems.The demonstration river in this study is a secondary urban river with a drainage area of about 16 square kilometers.The basin is rapidly developing into commercial,industrial,multi family and single family residential properties.Integrating environmental science and engineering in the initial stage of the demonstration,the river was evaluated,including habitat,biodiversity,trees and land-use change,and hydrological/geomorphic conditions in the river,in order to analyze the ecological services provided by the river.
