1990—2017年济南都市圈乡村地域功能的时空演化

Temporal and Spatial Evolution of Rural Regional Functions in Jinan Metropolitan Area from 1990 to 2017

利用1990—2017年的面板数据,对济南都市圈各区(县)的生态保育功能进行核算,借助GeoDa软件对乡村地域功能时空演化进行探索性空间数据分析。结果表明:从时间角度来看,济南都市圈乡村地域功能的总价值呈现快速增长的态势,由636.01亿元增长到13 929.69亿元,工业发展功能始终占据主导地位;从空间角度来看,生态保育、农业生产、工业发展及社会保障4类地域功能的空间相关性皆为正,生态保育功能的高值主要集中在研究区的东南部且空间演化并不剧烈,农业生产功能的高值在南部比较稳定且空间相关性强,工业发展功能的高值自东向西逐渐转移,社会保障功能由东南部高值集聚向空间均衡分布转变。

Based on panel data from 1990 to 2017,the ecological conservation function of every district(county)in Jinan metropolitan area was calculated,and the exploratory spatial data analysis of temporal and spatial evolution of rural regional functions was conducted by using GeoDa software.The results show that from the temporal point of view,the total value of rural regional functions in Jinan metropolitan area shows a rapid growth trend,which is from 636.01 billion yuan to 13929.69 billion yuan,and the industrial development functions are always dominant.From the spatial point of view,the spatial correlation of four types of regional functions such as ecological conservation,agricultural production,industrial development and social security is positive.The high value of ecological conservation function is mainly concentrated in southeast of the study area,and the spatial evolution is not dramatic.The high value of agricultural production function is in south of the study area,which is relatively stable and highly spatially correlated.The high value of industrial development function gradually shifts from east to west.The social security function changes from high value agglomeration in southeast to spatially balanced distribution.
