水域水岸水量水质统筹的水资源保护空间区划体系构建OA

At present,there is no zoning grasp for water resources protection planning.The protection objectives are mainly based on water function zoning or water environment function zoning.The zoning only delineates a single water quality target for water area protection and fails to fully reflect the protection requirements for water areas,shores,water quantity,and water quality.The safeguarding of water resources' inherent natural properties and societal service functions remains operationally challenging.To this end,this study proposed to construct a water resources protection space zoning system.It comprehensively considered the water area of river and lake water resources protection,the basic spatial range of shores,the quality characteristics of water resources in the watershed,the functional attributes of water bodies,and the regional spatial differences and constructed a comprehensive territorial zoning system based on"geographical division,functional classification,and control classification"and water quantity and water quality coupling.In terms of protection factors,the ecological base flow and the minimum discharge water index and the target of the control section were constructed.The geographical division was divided into the estuary area,river network area,and inland area.The functional classification was refined according to the types of water bodies,such as tidal river network,non-tidal river channel,and lake reservoir.Management and control classification docking integrated existing zoning results,such as water environment function zoning,water function zoning,and shoreline protection and utilization planning.This zoning system can provide a scientific basis for the protection,rational development and utilization of water resources,and also can serve as a valuable reference for water resources protection in other regions.
