基于TM遥感图像的宁波土地利用动态监测

Land Use Dynamic Surveying Based on the Interpretation of TM Image

利用TM和SPOT卫星遥感图像,以及相应卫星影像图、土地利用专题图等多种形式的资料,针对宁波土地利用动态监测的实际需要,进行有关遥感信息专题提取和应用的实证研究。

The principle and methods for dynamic monitoring land use changes and timely updating the database of land resource using the technology of remote sensing (RS) are discussed. Based on the TM, SPOT image, land use change in Ningbo urban fringe are outlined by using a series of computer-assisted mapping and spatial analysis operations, such as overlying, cartography reclassification etc. The landscape features, spatial extension tendency of Ningbo urban fringe are also summarized.
