通州市土地利用总体规划偏离度评价

结合上一轮土地利用总体规划的调控要求,对江苏省通州市1997-2005年的土地利用动态变化进行了定量研究,进一步分析了土地利用变化的驱动因素,对土地利用总体规划的实施效果进行了评价.结果表明,在研究时段内通州市的土地利用变化总体特点为农用地(特别是耕地)大量减少,建设用地急剧增加,未利用地变化不大;土地利用变化趋势差异明显,以2001年为分界点前后分为两个阶段,前一阶段土地利用系统有序度较高且相对稳定,后一阶段土地利用变动相对剧烈,土地利用空间结构变得复杂.通州市土地利用变化与土地利用总体规划各类用地控制目标偏离程度差异很大,土地利用总体规划的实施效果欠佳.

Evaluation of the Deviation Degree of Landuse Planning in Tongzhou City of Jiangsu Province

By considering the regulation requirements of previous general landuse planning and revealing the dynamic change of landuse in Tongzhou from 1997 to 2005,the study evaluates the implementation effects of general landuse planning based on the analysis of the driving factors of landuse changes. The evaluatio n ind-icates that the total characteristic of the landuse shift is that far mlands (especially arable land) decrease and construction land increases abruptly,while no n-use land has a little change.The difference of landuse shift is obvious.It can be divided into two phases by taking year of 2001 as a cutting point: in the former phase, the landuse system is ordered and fairly steady and in the latter phase, how ever, there is an intense fluctuation and the landuse space structure becomes complicated. There is a vast difference betw een landuse shift and the deviation degree of the control target of all kinds of landuses. The general landuse planning in Tongzhou is not implemented very well.
