池州市“三生”空间格局演变特征及驱动因素分析

Analysis on the Evolution Characteristics and Driving Factors of the Spatial Pattern of "Production,Life and Ecology" in Chizhou City

研究“三生”空间格局演变特征及驱动因素,是优化国土空间发展格局的重要前提。以池州市为例,通过识别2000年、2005年、2010年、2015年、2020年五期遥感影像数据,采用转移矩阵、景观格局指数和地理探测器等方法分析2000—2020年池州市“三生”空间格局演变的外在特征及内在驱动因素。结果表明:池州市“三生”空间总体上呈现出生产空间显著缩减和生态、生活空间逐渐扩张的趋势;生活空间演变呈现显著的经济性特征,生产和生态空间演变呈现出被动性和政策性特征,但池州市总体“三生”空间结构态势并无较大变化,体现出其空间格局演变的局部渐变性和总体稳定性;自然要素是“三生”空间格局演变的基础限制条件,社会经济是主导驱动因素,交通区位是辅助驱动因素。

Studying the evolution characteristics and driving factors of the spatial pattern of "Production,Life and Ecology"( "PLE")is an important prerequisite for optimizing the spatial pattern of national land.Taking Chizhou City as an example,by identifying the five periods of remote sensing image data from 2000 to 2020,the external characteristics and internal driving factors of its spatial pattern evolution are analyzed by means of transfer matrix,landscape pattern index and geographical detector.The results show that:On the whole,the "PLE" space in Chizhou City shows a significant reduction in production space and an obvious expansion in ecological and living space;The evolution of living space presents significant economic characteristics,and the evolution of production and ecological space presents passive and policy characteristics,but the overall "PLE" spatial structure situation of Chizhou City has not changed significantly,reflecting the local gradual change and overall stability of its spatial pattern evolution;Natural factors are the basic limiting conditions for the evolution of the spatial pattern of "PLE";Social economy is the leading driving factor,and traffic location is the auxiliary driving factor.
