摘要
以新疆阜康地区为研究区,利用遥感和GIS技术及数理统计学方法,利用ERDAS软件,通过对70年代MSS和2000年ETM影象的几何校正、图象增强、应用目视解译方法,在地理信息系统软件ArcGIS中编制两期生态景观图,利用矢栅转换和叠置功能来研究土地及植被类型的面积及空间分布状况在两期图中的变化,并通过土地利用与土地覆被变化来研究70年代到2000年西部干旱区土地及植被类型变化过程和趋势。
Making use of the technology of remote sensing with GIS, and the maths-physical statisticses method, studied on the Fukang area of Xinjiang Province, using the software of ERDAS, according to the geometry correction and image enchancement of 70＇s MSS and 2000 ETM image, weaving two period landscape diagram in the software ArcGIS of the geography information system by the method of visual interpretation, studying the variety of the land and vegetation types in the area and spaces in the diagram by the way of vector and raster data conversion and overlapping, according to the diversification of land using and covering to study the diversification tendency and process of the land and vegetation types from 70＇s to 2000 in the western dry area.
