摘要
以黄河流域山东段为研究区,结合2000—2020年土地利用数据和社会经济统计数据,从规模特征、动态变化和分布特征等方面对国土空间时空演变格局进行多维度定量分析,并采用地理探测器探析其驱动因素。结果表明:(1)规模特征方面,除乡村生活空间规模相对稳定外,其他各类国土空间增减特征显著;(2)动态变化方面,不同国土空间类型间的动态变化差异明显,且各区县单元综合动态度呈现东北高、西南低、中部突出的特征;(3)分布特征方面,各国土空间面积变化具有显著的空间集聚特征,这一特征在2010—2020年相对减弱;(4)驱动因素方面,研究区国土空间面积变化受到地形地貌、水热状况、区位情况以及社会经济等多种因素的共同影响,自然环境因素是国土空间格局演变的重要地理基础,社会经济发展则发挥着关键的推动作用。
Taking the Shandong section of the Yellow River Basin as the study area,combining the land use data and socio-economic statistics from 2000 to 2020,the spatial and temporal evolution pattern of the national land space is quantitatively analyzed in terms of scale characteristics,dynamic changes and distribution characteristics in a multi-dimensional manner,and geo-detectors are used to explore its driving factors.The results show that:(1)In terms of scale characteristics,except for the relatively stable scale of rural living space,other types of national land space have significant characteristics of increasing or decreasing.(2)In terms of dynamic changes,there are obvious differences in the dynamic changes among different types of land space,and the comprehensive dynamic attitude of each district and county unit presents the characteristics of“high in the northeast,low in the southwest,and prominent in the centre”.(3)In terms of distribution characteristics,the changes in the spatial area of each land have significant spatial clustering characteristics,which will be relatively weakened in 2010-2020.(4)With regard to driving factors,changes in the spatial area of the national territory of the study area are affected by a combination of factors,including topography and geomorphology,hydrothermal conditions,location and socio-economics,with the natural environmental factors serving as an important geographic basis for the evolution of the spatial pattern of the national territory,and socio-economic development playing a key role as a driving force.
