城市河道生态补水技术研究

Study on Ecological Water Supplement Technology of Urban Rivers

针对城市化进程下的河道生态环境功能衰退、水质下降和生物多样性减少等问题,论文分析了城市河道生态补水技术的现状和难点,引入了SWAT水文模型用于水资源管理和决策支持,提出了结合SWAT模型的生态补水技术。结合商洛市城市河道进行分析,结果表明水资源分配技术下的洛河月平均流量为9.4 m^(3)/s,水资源短缺技术下的洛河月平均流量为8.7 m^(3)/s,两种技术下的河道流量都发生明显改善。

In view of the problems such as the decline of river eco-environmental function,the decline of water quality and the decrease of biodiversity in the process of urbanization,the present situation and difficulties of ecological water replenishment technology for urban rivers are studied and analyzed.SWAT hydrological model is introduced for water resourcesmanagement and decision support,and ecological water replenishment technology combined with SWAT model is proposed.Based on the analysis of urban waterways in Shangluo City,the results show that the averagemonthly discharge of Luohe River underwater resources allocation technology is 9.4m^(3)/s,and that underwater resources shortage technology is 8.7m^(3)/s,and the river flowunder both technologies has been obviously improved.
