区域耕地数量变化与工业化、城市化进程相互关系探讨——以江苏省为例

摘要/Abstract

摘要：

通过对江苏省1996～2004年耕地数量的总体变化与空间差异分析，揭示了全省耕地在总体上处于递减状态、在空间上苏北地区向苏南地区耕地递减程度逐渐增加的规律。从处于不同工业化与城市化阶段的城市及其各自耕地变化状况的对比分析，得出如下结论：耕地变化程度在处于不同工业化、城市化发展阶段的县市具有明显的差异，且与工业化、城市化的进程与状态具有一定的内在关系；对产业非农化、城市化率与耕地变化的进一步分析表明：产业非农化、城市化递变系数与耕地递变速率具有一致性，耕地减少对工业化发展的贡献较大，但其持续减少状况与当前所处工业化阶段不太相符，而城市化率变化与耕地变化状况存在时间差异，说明城市化对耕地变化的影响有一定的滞后性。

Abstract:

Data of cultivated land in Jiangsu Province from 1996 to 2004 are analyzed by statistics.The results showed that the change of the cultivated land in the research region was descending and the descending rate was increasing from the North to the South.〖JP2〗This paper mainly focuses on the corresponding〖JP〗 type of cultivated land use to different stages and state of industrialization and urbanization respectively and the regularity between them.In order to determine the relationship between the cultivated land and the stage of industrialization and urbanization,we try to analyze the different stage of industrialization and urbanization in each cities and the change rate of the cultivated land according to comparison of each other.The study showed that there were obvious discrepancies of the cultivated land change in the different stage of cities' industrialization and urbanization.The cultivated land's descending rate takes on the drastic change,rapid change,and slow change (or steady change) in the upperstage,mediumstage,and initialstage of the industrialization respectively.In the same way,there are different changes (drastic change,rapid change,and slow change or steady change) of cultivated land in the initialstage,acceleratingstage,and endingstage of urbanization.At last,industrialization and urbanization index were selected to determine the extent which related with the change of cultivated land.The two coupling coefficients and cultivated land coefficient showed a strong consistency through a comparison.The descending rate of cultivated land was accelerating with the development of industrialization,and the area of the cultivated land was decreasing with the advancing of urbanization.This result showed that the development of industrialization at present mainly benefits from the descending of the cultivated land,and the development of urbanization result in the decreasing of cultivated land,but the change between two coefficients is not happened simultaneously.
