水文调控在山地城市河流生态修复中的应用探讨

Discussion on the Application of Hydrological Regulation in Water Ecological Restoration of Rivers in Mountainous Cities

随着城市化进程的加快,城市河道污染现状与其景观、水源、分洪等功能定位之间的矛盾日益突出。文章在介绍城市河流水文现状和生态基流重要性的基础上,以城市河道水生态恶化问题为研究对象,以山地城市水文循环为主要研究内容,重点提出对应的山地城市河流生态基流量对应计算方法以及河道补水措施,初步分析了补水活水的综合应用情况,以期保障河道生态基流量、提升河道水动力、改善河道水生态、加强水体自净能力,为山地城市河道水生态修复指引新方向。

With the acceleration of urbanization,the contradiction between the current situation of urban river pollution and its function of landscape,water source and flood diversion has become increasingly prominent.Based on the introduction of the current hydrological status of urban rivers and the importance of ecological base flow,this paper takes the problem of urban river water ecological deterioration as the research object,takes the mountainous city hydrological cycle as the main research content,focuses on the corresponding calculation method of mountainous city rivers’ecological base flow and water replenishment measures,and preliminarily analyzes the comprehensive application of water replenishment,in order to ensure the ecological base flow,enhance the water dynamics,improve the water ecology,strengthen the self-purification capacity of the water body,and guide a the new direction of river water ecological restoration in mountainous cities.
