摘　　要：针对三次调查取消线状地物以及二次调查以来市、县两级行政区划调整频繁的特点,以江苏省二次调查成果、三次调查成果和最新行政区划为基础,研究探讨了一种基于线状地物重构面的流量分析方法并进行了精度验证,为准确分析江苏省三次调查和二次调查十年间土地利用变化情况提供了技术依据。In view of the cancellation of linear features in the third national land survey and the frequent adjustment of city and county administrative divisions since the second national land survey.Based on the results of the second national land survey,the third national land survey and the latest administrative division in Jiangsu province,a flow analysis method based on the reconstruction surface of linear features is studied and its accuracy is verified.This method provides technical basis for accurate analysis of land use change in Jiangsu province during the past ten years.
