江西省产业升级中耕地数量变化的区域差异

根据江西省11市1995~2004年数据,把江西省划分为3种类型区:产业结构未变化且处在工业化中期区(Ⅰ类地区);工业化初期向工业化中期升级区(Ⅱ类地区);农业经济发达期向工业化初期升级区(Ⅲ类地区),然后分析了各类型区耕地数量变化的差异。主要结论如下:三大类型区随着产业结构的不断升级,耕地减少的幅度呈逐渐缩小的趋势,经济发展对资源投入的依赖性在逐渐减少,各产业对耕地数量的变化影响程度在逐渐降低,耕地转化效益在不断提高。

Regional Difference in Quantitative Changes of Cultivated Land in Industry Upgrading of Jiangxi Province

Based on the data of 11 cities in Jiangxi province from 1995 to 2004,Jiangxi province can be divided into 3 types of regions,which are region of industrial structure unchanged and in the industrialization metaphase(region of Ⅰ type),region of upgrading from initial stage to metaphase of industrialization(region of Ⅱ type) and region of upgrading from developed agricultural economy stage to initial stage of industrialization(region of Ⅲ type).Then the regional difference in cultivated land changes is analyzed,the main conclusions are as follows: along with upgrading of industrial structure,the decreasing extent of cultivated land in quantity appears the trend of gradual reducing,the dependence of economic development on resource devotion is reducing,the effects of different industries on changes of cultivated land are falling,and the conversion benefits of cultivated land are increasing.
