摘要
利用遥感与地理信息系统技术进行土地资源调查和动态变化监测已为人们所共识。由于土地利用与土地覆盖的复杂性 ,利用遥感技术进行土地利用变化动态监测时 ,遇到了许多具体问题。从应用的角度出发 ,重点在土地利用与土地覆盖的关系、影像的选择与处理、动态监测方法的选定与综合及其它多方面知识的参与等几个方面进行了探讨。这些问题的解决 ,将会在很大程度上提高土地利用变化监测的精度。
Remote sensing and GIS have been widely used in dynamic detection of land use changes, which have been commonly recognized by many peoples. Because the land use and land cover are very complex, we meet many problems in land use detection by remote sensing. In this paper, we mainly discuss several key problems in actual applications of remote sensing technology to land use changes detecting effectively, such as the special relations between land use and land cover, selection and handling of images, comparing and synthesizing of several different means, participating of much knowledge in many other sides and so on. If those problems can be well resolved, the precision can be well improved to much extent, and the result may be better .
