江苏省农地依存度的时空变化

Temporal and Spatial Changes of Farmland Dependence in Jiangsu Province

基于对江苏省13个地级市的农地依存相关数据进行分析发现:(1)农地依存度的重心由苏南苏中地区逐渐向苏北地区移动,印证了苏南苏中地区的产业结构不断趋向于二三产业,第一产业发展逐步变缓,而苏北地区虽然在依靠第一产业同时,不断发展二三产业,但发展速度较为缓慢。(2)2008年以后江苏省农地依存度空间变化基本稳定,苏北地区为农地依存度重心,苏南苏中地区农地依存度较低。

Based on the analysis of the farmland dependence data of 13 prefecture-level cities in Jiangsu Province,we found that:(1) The center of agricultural land dependence gradually moved from south and central Jiangsu to north Jiangsu,which proved that the industrial structure of south and central Jiangsu tended to the secondary and tertiary industries,and the development of the primary industry gradually slowed down. However,although the northern Jiangsu relied on the primary industry,it continuously developed the secondary and tertiary industries,but the development speed was relatively slow.(2) After 2008,the spatial change of land dependence in Jiangsu province was basically stable. The north of Jiangsu province was the center of land dependence,while the south and middle of Jiangsu province were relatively low.
