利用遥感技术进行县级土地利用变更调查方法的研究

Study on the Method for County-level Land Use Change Survey Using Remote Sensing Technology

根据县级土地利用变更调查工作的特点和要求,结合不同卫星遥感数据的监测精度、可获取性、经济可行性以及3S技术综合集成的特点,在总结国内外土地利用动态遥感监测应用研究的基础上,提出了不同比例尺县级土地利用变更调查应选取的遥感数据及更新的技术流程。

The paper puts forward the selection of remote sensing data for land-use map revising with different scales and its technique flow, according to the characteristics and requirements of county-level land-use change survey. The analysis was also made on monitoring accuracy, acquisitiveness, economic viability and the characteristics of integrating data under 3S technique and other research findings on dynamic monitoring of land-use by remote sensing at home and abroad.
