River ecological restoration is an important step for improving water quality and maintaining the stability of the river ecosystem, as well as a key measure for fulfilling overall requirements of water-ecological environment protection in key basins in the 14th Five-year Plan. Taking Shengjiawan River course, a tributary of Yuhuitang, in Jiashan County as the research area, riverine buffer zone and water ecological restoration projects were implemented and carried out. In the light of seriously occupied ecological space, damaged habitat in some river sections, reduced biodiversity, unstable river water quality and so on in the region, the overall scheme of ecological restoration project for Shengjiawan River course was presented as following innovative idea of "protection-restoration-development". With comprehensively improving the water-ecological environment quality and building a healthy and stable water ecosystem as the targets, the measures like non-point source pollution control, ecological space restoration and water ecological restoration were taken, including the construction of artificial wetland (17 700 m2) and ecological grass planting ditch (2 200 m), riverine vegetation buffer zone (30 m×1 480 m), ecological transformation of riverbank (1 210 m) and underwater forest ecological restoration project (20 400 m2). By ecological restoration of Shengjiawan River course, the ecological environment in this area was comprehensively improved, "clear water and green banks" were observed and the biodiversity of the water body was restored.
