基于多源数据的"三生"空间识别及其城乡梯度分异特征
Identification of production-living-ecological space and its urban-rural gradient differentiation based on multi-source spatial data:a case study of Xuzhou
摘要
Abstract
Refining and identifying the types of"Production-Living-Ecological"(PLE)space,and exploring their spatiotemporal evolution and urban-rural gradient differentiation characteristics,serves as a crucial foundation for optimizing the development pattern of territorial space.Taking Xuzhou City as an example,this study refines the PLE space types and employs PLE function scoring method,PLE spatial function adjustment based on multi-source data,and gradient analysis to reveal spatiotemporal evolution and its urban-rural gradient differentiation characteristics of PLE space in Xuzhou from 2010 to 2020.The results show that:(1)Eight types of PLE space were identified in Xuzhou,with composite spaces exceeding 79.10%of the total area,and some space types changed significantly.(2)The spatial distribution of PLE space types exhibited a pattern of"globally dispersed and locally clustered".The urban production-living space is aggregated in the form of multiple cores around the centers of city,counties and districts and continuously expands.The rural production space is distributed in a"ring"shape around the built-up area,while the rural living space is mainly distributed in the border area of Xuzhou.(3)The most pronounced transformation during 2010-2020 occurred between rural production space and rural production-ecological space.(4)From 2010 to 2020,the PLE space mainly presented the gradient distribution characteristics of"expansion of the urban production-living space in the urban core,transition of the rural production-ecological space to the urban production-living space in the suburban,and dominance of rural production-ecological space in the outer fringe regions".The study demonstrates that the combination of the improved PLE space classification and identification method and the gradient analysis can reveal PLE space's spatiotemporal evolution and its urban-rural gradient differentiation characteristics,and supports decision-making in territorial spatial planning and refined management.关键词
