摘要

选择干旱区典型绿洲香日德地区为研究区

以1987年和1999年两期不同时相的Landsat TM遥感影像为数据源

结合实地调查所获得的大量数据

利用遥感、全球定位系统以及地理信息系统技术(3S技术)对图像进行综合技术处理

获取该地区土地覆盖变化的动态信息。分析总结了香日德绿州土地利用时空变化的规律性和驱动因子

为合理开发绿洲

可持续发展绿洲资源以及改善生态环境等提供了新的研究方法和科学依据。

Abstract

This research takes the Xiangride oasis as a study area

and takes temporal Landsat TM images in 1987 and 1999 as data sources. Based on a great many data obtained in field spots

temporally different images in the two terms were processed accurately through the application of 3S techniques (RS

GPS and GIS). The dynamic change in land cover was analyzed

and the temporal-spatial change characteristics and the driving forces were summarized. A new research method and some suggestions were presented for the sustainable development and environmental improvement of the oasis.
