基于生态近自然理论的城市河流修复技术

Urban river restoration technology based on ecological water conservancy theory

由于城市河流污染严重,人工化问题十分突出,基于生态近自然理论,开展河流修复技术的研究。从自然化原理、自然生境构建、护岸材料选取、近自然风貌运用、近自然植物搭配等角度,对城市河流水环境修复技术进行了论述。典型工程应用表明,采用基于底泥预处理、沉水植物、挺水植物、微生物应急调控的水质提升技术,并合理构建栈道景观、河道植物绿化景观,可以营造出生态宜居的生活环境。生态水利修复技术具有广阔的应用前景。

Due to the serious pollution of urban rivers,the problem of artificialization is very prominent.Based on the ecological approach to nature,research on river restoration technology had been carried out.From the perspectives of naturalization principles,construction of natural habitats,selection of revetment materials,use of near-natural features and near-natural plant collocation,the technology of urban river water environment restoration was discussed.Typical engineering application showed that the use of water quality improvement technology based on sediment pretreatment,submerged plants,emergent plants and microbial emergency regulation and reasonable construction of plank road landscapes and river plant green landscapes can create an ecologically livable living environment,and ecological water conservancy restoration technology had broad application prospects.
