Probe Into The Comprehensive Treatment Of "Reservoir Disease" In Large-scale Old Reservoirs Taking Zhexi Reservoir In Anhua County As An Example

Large reservoirs play the roles of "water diversion and energy storage,flood control and power generation" in flood control and agricultural irrigation,providing strong support for the development of rural production and living for a long time.However,as a comprehensive water conservancy facility,as time goes by,sediment deposition,geological disasters,water deterioration and other "reservoir diseases" will occur in large reservoirs that have been operating for a long time.It is helpful to extend the service period of the reservoir,deal with the harm of the "reservoir disease" scientifically,and improve the comprehensive use efficiency of the reservoir.Taking Zhexi reservoir in Anhua as an example,the large "reservoir",the major forms of harmful influence,the reasons were analyzed,and summarize the ecological water purification,land ecological protection,ecological relocation "means of comprehensive control,as the" disease "reservoir study and comprehensive treatment of providing a certain reference.The main contents of the paper include:1.Summarize the manifestations and hazards of reservoir diseases."Reservoir disease" mainly manifests in the ways of landslides,silting and water deterioration,which not only reduces the flood discharge capacity of the reservoir,but also leads to the unstable structure of the reservoir,aggravates the water body of the reservoir,and has a great impact on the structure of the reservoir,local climate and even the ecological environment.2.Analyze the main causes of reservoir diseases.The causes of reservoir disease are complicated,including natural and social reasons.The causes of most reservoir diseases are mainly caused by the lack of scientific planning in the early stage,the limitation of the technical level at that time,the erosion of the water body in long-term operation,and the excessive exploitation of production and development.3.Explore measures for comprehensive treatment of "reservoir disease".Combination of reference and use for reference the experience of other reservoir of governance,the key to we zhe creek reservoir management measures,for example,to analyze "reservoir disease control measures,mainly include: ecological water purification,repel and cages and blocking fish farming,reducing eutrophication,regular cleaning rubbish floater maintaining water quality safety,large water fish can enhance water self-purification ability,etc.;Ecological protection of coastal areas,scientific establishment of ecological protection zones,large-scale production and development of restricted reservoir areas,ecological compensation for afforestation and restoration of engineering projects,etc.;Personnel again ecological relocation,including centralized resettlement into the urban areas,to create the characteristics of rural resettlement communities,the construction of beautiful rural villages,and increase the demolition of old land reclamation to return farmland to forest.
