摘要
应用SPOT 4多光谱遥感数据 ,结合GPS (Globalpositioningsystem)所测定的地面控制点和地面景观类型调查数据 ,对新疆塔克拉玛干沙漠南缘中部和田地区的策勒荒漠 绿洲景观分类及其特征进行了研究 .利用ERDASIMAGINE图像处理软件 ,对SPOT 4卫片进行几何纠正、投影转换和监督分类 ,形成研究区的景观分类图 ,对策勒绿洲的景观分布格局进行了定性的描述 ,并进一步探讨了SPOT及其它遥感数据在荒漠 绿洲景观研究中的应用研究前景 .
The landscape surounding Qira osais at the southern fringe of the Taklamakan Desert in China was analyzed by using the SPOT 4 multispectrum remote sensing data and GPS (global positioning system) data.The SPOT 4 scene was projected into an UTM grid,and a supervised classification by ERDAS IMAGINE software was applied. In total,13 landscape units could be distingushed,and a 'frame of reference' was set up for establishing monitoring system of landscape patterns dynmics. Limitations,possible improvements and further applications of the approach were discussed.
