用MSS底片和TM图像作为数据源,通过扫描成像、假彩色合成和空间配准以形成彩色遥感图像。RS和GIS相结合,从卫星图像解译出土地资源利用类型,利用ARC/INFO进行自动统计,并输出各类土地面积,对巫山县近30a来土地利用动态变化进行研究。得出巫山县30a的土地利用变化和环境变化规律,并对造成这种变化的驱动力进行探讨和分析。为今后更加合理地利用土地和相关土地政策的制定提供了决策支持。

A technololgy streamline to form a pseudo-color image from MSS hegative by scanning, pseudo-color composing and spatially correction was introduced in this paper. Thirty years' land-use dynamic changes of Wushan county were analyzed by combination of RS and GIS. A method to use satellite image to interet land-use types and a technique to auto-statistics diversfied data and export area of each land-use type Arc/info GIS software were applied. At last, the charactristic of the thirty years' dynamic land-use and environment changes of Wushan County were elicited and its driving force of the land-use dynamic changes was analyzed. This paper can proivde infomation for govenments on land utilization and establishment of relevant policy sustainable land-use.
