扬州市“三生”空间演化及驱动力研究

Study on the Spatial Evolution and Driving Force of “Production-living-ecology” Space in Yangzhou

综合运用GIS空间分析及土地利用转移矩阵等方法,分析扬州市2000年、2010年及2018年土地利用数据,对其国土空间进行“三生”空间划分和功能评分,以此研究其“三生”空间格局演变及其驱动力。研究表明:一是扬州市“三生”空间的演化在2000—2010年间速度较快,特征相对明显,在2010—2018年间的演化明显更加碎片化,并且整体演化速度放缓;二是扬州市在合适政策的指导下,城市的生产水平与生态水平均保持良好,生活水平持续上升;三是扬州市城镇发展的核心区域在沿江区域,城镇化的发展趋势非常明显;四是扬州受城镇化影响非常明显;在此期间出现的耕地占用等问题也较为突出。

The land use data of Yangzhou City in 2000, 2010 and 2018 are analyzed comprehensively by using GIS spatial analysis and land use transfer matrix, and the spatial division and function score of“production-living-ecology”space of its land space are carried out to study the evolution and driving force of its spatial pattern of “production-living-ecology”space. The research shows that: First, the evolution of the“production-living-ecology”space in Yangzhou City was relatively rapid from 2000 to 2010, with relatively obvious characteristics. The evolution was significantly more fragmented from 2010 to 2018, and the overall evolution speed slowed down. Second, under the guidance of appropriate policies, Yangzhou has maintained a good level of production and ecology, and its living standard has continued to rise. Third, the core area of Yangzhou’s urban development is the riverside area, and the trend of urbanization is very obvious. Fourth, Yangzhou is significantly affected by urbanization. During this period, cultivated land occupation and other problems are also prominent.
