摘　　要：目前对土地利用/覆被变化遥感监测解译中不确定地物的补判通常利用GPS手持接收机在野外进行,这种方法常常耗财、耗时、耗力。提出利用Google Earth上部分地区具有的高分辨率影像,对土地利用/覆被变化遥感监测解译过程中部分不确定地物进行补判的新方法。结果表明,利用Google Earth在室内就可以对遥感监测解译过程中的部分不确定地物进行可靠补判,大大提高了土地利用/覆被变化遥感监测效率。The re-interpretation of uncertain ground objects in the interpretation of land use/cover changes with remote sensing monitoring is generally made in the open by using GPS portable receiver at present.More money,more time and more labor are needed by using this method.A new method for the re-interpretation of some uncertain ground objects in the interpretation process of land use/cover changes with remote sensing monitoring was brought forward because of high resolution images in some areas on Google Earth.The results showed that reliable re-interpretation could be made on some uncertain ground objects indoors by using Google Earth.Thus the efficiency of land use/cover changes with remote sensing monitoring could be greatly enhanced.
