喀斯特山区“三生”功能时空演变及驱动机制——以贵州省为例

Spatio-temporal evolution and driving mechanism of production,living and ecological function in karst mountainous areas:a case study of Guizhou Province

“三生”功能是指生产、生活和生态功能所提供的产品或服务,其功能分异可为国土空间规划提供科学指导。以贵州省88个县域单元为研究对象,运用数理统计、ArcGIS空间分析和地理探测器系统探究喀斯特山区“三生”功能时空演变特征与内在驱动机制。结果表明:①2000—2018年各县域“三生”功能综合指数均呈现不同程度的下降趋势,其中生产、生活、生态功能指数分别下降18%、38%、6%;②生产、生活、生态功能高值区分别主要位于西部和北部、中西部、东部地区,“三生”功能空间分异格局主要源于生产和生态功能变化;③“三生”功能时空演变的主导因子是第三产业生产总值、交通运输用地和人均可支配收入。研究成果可为喀斯特山区乡村振兴、区域高质量发展提供科学依据和决策参考。

Production,living and ecological function refer to the products or services provided by production,living and ecological functions.Its functional differentiation can provide scientific guidance for territorial space planning.Taking 88 county units in Guizhou Province as the evaluation objects,this study systematically explored the spatio-temporal evolution characteristics and internal driving mechanism of"production-living-ecological"function in karst mountainous areas by using mathematical statistics,spatial econometrics and geographic detector methods.The results showed as follows:(1)From 2000 to 2018,the comprehensive indices of“production-living-ecological”function showed a decreasing trend in different degrees,with the indices of production,living and ecological function decreasing by 18%,38%and 6%.(2)The high-value areas of production,living and ecological functions were mainly located in the western and northern regions,the central and western regions and the eastern regions respectively.The spatial differentiation pattern of"production-living-ecological"function was mainly derived from the changes of production and ecological functions.(3)The leading factors of the spatial and temporal evolution of“production-living-ecological”function were the GDP of tertiary industry,land for transportation and per capita disposable income.The research results can provide scientific basis for rural revitalization in mountainous areas and high-quality regional development.
