深圳市水源水库前置库湿地建设及净化面源污染的防治

Construction of pre-dam wetland of water source reservoir and control of non-point source pollution in Shenzhen City

近几年,水库水源地污染对水质保护造成了严重威胁,为保护水库水源、防治环境污染,将水资源生产潜力充分发挥出来,积极应用前置库技术,充分利用其费用低、适用于多种条件、多方受益的优点,已经成为当前水库水源防治污染的重要措施。基于此,本文主要以深圳市为例,分析深圳市水源水库存在的生态与环境方面的突出问题,在充分调查水源水库污染现状、水质状况、生态系统结构及功能的基础上,探索前置库湿地在控制水库面源污染、完善生态修复和改善水质的内在机理,从而为深圳市水源水库的生态修复和水环境保护的管理提供科学决策基础。

In recent years,the pollution of water source has posed a serious threat to water quality protection.To protect the water source of reservoir,prevent and control the environmental pollution,and give full play to the production potential of water resources,pre-dam technology should be actively applied.It has the advantages of lower cost,high flexibility and multi-benefits,which has become an important measure to control pollutions of reservoir water sources.Based on this,the paper mainly takes Shenzhen as an example to analyze the prominent ecological and environmental problems existing in the water source reservoir.On the basis of a comprehensive investigation of the pollution status,water quality,ecosystem structure and functions of the reservoir,the working mechanism of pre-dam wetland in controlling water source pollution and improving ecological restoration and water quality is explored.Thus,the study might provide a scientific decision-making basis for the ecological restoration of water source reservoirs and management of water environment in Shenzhen City.
