Research on County Territorial Spatial Ecological Restoration Zoning Based on GIS Software—A Case Study of Songtao County in Guizhou Province
Territorial spatial ecological restoration is an important means to improve the efficiency and quality of territorial spatial development and optimize land space.The paper uses the spatial analysis tool of GIS software,takes the natural geographical conditions,spatial differentiation of eco-functions,and main ecological issues of Songtao county in Guizhou province as the basic research reference,selects and forms three levels of eleven ecological restoration zoning indicators to discuss the territorial spatial ecological restoration zoning of Songtao county.Under the condition of understanding the overall pattern of the county and ensuring regional integrity,the first-level ecological restoration zones were divided.The second-level ecological restoration zones were divided according to the regional dominant eco-functions.Finally,according to the main ecologically sensitive issues and human disturbance characteristics,the key areas of ecological restoration were identified and the third-level ecological restoration zones were delimited.Accordingly,Songtao county is divided into restoration zones including five types of first-level,four types of second-level,and four types of third-level,which effectively clarifies the eco-sensitive and eco-degradation issues existing in the county.On these bases,the protection and restoration measures are proposed with"overall layout-zoning management"as the main principle,and various topics as the starting point,including soil and water flow,watershed management,soil and water conservation,rocky desertification,mine ecological restoration,etc.
