3S技术在龙滩水电站库区土地利用类型监测中的应用

Application of 3S Techniques in the Type Monitoring of Longtan Reservoir's Land Utilization

土地利用类型监测的目的是掌握土地利用现状及其动态变更,为相关部门及时提供土地利用、变更的信息。通过3S技术与常规手段的辅助,进一步对一系列遥感数据和实测数据的处理分析,建立解译标志,完成了对土地利用类型,土地植被的遥感图像的解译,利用地理信息系统软件Arcview3.0矢量化解译的图班,经统计分析,得出土地利用类型,从而为有关部门提供科学依据。

The goal of the type monitoring of land utilization is to know the present situation and the dynamic change of land utilization so as to provide the correlative department with the newest information of land utilization and variation. With the help of 3S techniques and conventional methods, we have processed and analyzed a series RS data and solid data and established an interpretation symbol for the interpretation of the types of land utilization and the RS images of vegetation. Then, the interpretation chart of GIS software Arcview3.0 is employed and analyzed statistically to obtain the types of land utilization so that scientific policy - making basis could be provided for the correlative department.
