滨海地区城市渠化河道生态修复实践

Ecological restoration engineering practice of canalized river in coastal area

以海南省东方市竹金沟为例,系统剖析修复对象存在的水生态问题,综合运用水文、环境科学、植物学、生态学等科学原理拟定生态修复工程设计思路,在设计应用中结合不同生境条件选择性提出水生态系统构建措施,并对生态修复过程中生境影响因子、水生植物作用、植物选择、种植区构建等进行探讨。可为区域建设强度大、周边用地紧张的城市渠化河道开展生态修复工程设计提供参考。

Taking the Zhujin Gully in Dongfang City,Hainan Province as an example,the water ecological problems existing in the restoration object were systematically analyzed.Based on the scientific principles of hydrology,environmental science,botany and ecology,design ideas for ecological restoration projects is formulated.In the design and application,the measures of water ecosystem construction were selectively proposed based on different habitat conditions,and the influence factors of habitat,the role of aquatic plants,plant selection and planting area construction in the process of ecological restoration were discussed.It can provide reference for ecological restoration engineering design of urban channelized river course with high regional construction intensity and limited surrounding land use.
