【摘要】：以西寧南川河綜合治理為例,對(duì)河道治理中生態(tài)修復(fù)、防洪保安、水文化水景觀建設(shè)等治理任務(wù)的有機(jī)結(jié)合進(jìn)行探討。通過分析南川河現(xiàn)狀及其存在的問題,采取建設(shè)沉沙池消減含沙量、全線截污去除污染源、雷諾護(hù)墊進(jìn)行生態(tài)護(hù)岸以及建設(shè)三級(jí)表流濕地等措施,削減水體中的污染物,改善河道水質(zhì),并結(jié)合河湟文化打造濱水文化長廊,提升城市品位。南川河整治項(xiàng)目實(shí)施后,一改原有河道兩岸雜亂無章的面貌,提高了河道行洪能力,河道水質(zhì)也得以改善。此外,該項(xiàng)目對(duì)于促進(jìn)河灘濕地恢復(fù)、提高河道生物多樣性、增強(qiáng)棲息地功能等方面效果顯著。在滿足河道生態(tài)流量的前提下,沉沙池沉沙率達(dá)到64.6%~72.3%,濕地建設(shè)能夠減少氨氮含量0.13 mg/L、BOD_5含量0.60 mg/L。南川河綜合整治工程遵循尊重自然、科學(xué)治理、發(fā)揮社會(huì)功能等原則,對(duì)今后生態(tài)河道的治理有一定的借鑒意義。
[Abstract]:Taking the comprehensive control of Nanchuan River in Xining as an example, this paper discusses the organic combination of ecological restoration, flood control and security protection, water culture and water landscape construction in river course management. By analyzing the present situation of Nanchuan River and its existing problems, the measures of reducing sediment content by constructing sediment sink, removing pollution sources by intercepting pollution on the whole line, ecological bank protection with Renault cushion and construction of tertiary surface flow wetland are adopted to reduce pollutants in water body. Improve river water quality and build waterfront culture corridor in combination with Hehuang culture to enhance city grade. After the implementation of the Nanchuan River Regulation Project, the disorderly appearance of both sides of the original river has been changed, and the flood discharge capacity of the river has been improved, and the water quality of the channel has also been improved. In addition, the project is effective in promoting wetland restoration, improving river biodiversity and enhancing habitat function. On the premise of satisfying the ecological discharge of river, the sedimentation rate of sediment sink reached 64.6% and 72.3%. Wetland construction can reduce ammonia content 0.13 mg / L ~ (-1) / L ~ (-1) BOD5 0.60 mg 路L ~ (-1) 路L ~ (-1) 路L ~ (-1) 路L ~ (-1) ~ (-1). The comprehensive regulation project of Nanchuan River follows the principles of respecting nature, managing scientifically and giving play to social function, which has certain reference significance for the future management of ecological river course.
