Monitoring and control of water-ecological space in the Dongting Lake region

The territorial spatial planning in the new era strengthens control of different functional spaces and emphasizes integrated coordinated development each space. Therefore, it is important to monitor “structure-function” characteristics water-ecological space based on context develop a management framework. Based land use social statistics, with help ArcGIS analysis, this paper examined structure function Dongting Lake study for 2010, 2015, 2020, generating framework proposing key initiatives. main results are as follows: 1) overall scale water ecological over 7,300 km 2 . Water bodies had largest share, followed by coastal terrestrial areas, while land-water ecotone was smallest. There small decrease during period. Yueyang space, Linli 2) comprehensive about 0.4000, increasing somewhat Among units, value highest Yuanjiang City, Jincheng City lowest. 3) From structural elements scientific zoning should be carried out combined delineation “three zones three lines.” Key initiatives such multi-scale multi-level control, access restrictions, determination ownership, pollution accountability, treatment restoration promoted.
