基于时相遥感数据艾里克湖土地利用变化研究

Study of Land Use Change in Alice Lake Area Based on Remote Sensing Data

为了量化艾里克湖所在区域(乌尔禾)生态演变规律,选用了乌尔禾区为研究对象,使用4个时段TM遥感图像(1976,1989,2000,2009年)作为数据源,利用RS,GIS技术,对1976年至2009年研究区土地利用特征的时空变化进行了分析。研究表明:从20世纪70年代至今,乌尔禾区面积林地,草地和其他土地的比例正在逐步减少,耕地和工业用地的比例逐渐增加,居民和道路是非常小的量的增加,水域面积较大变化。

Taking Wuerhe District as an example, and introducing the use of TM from multi--temporal remote sensing images in land resource information,this article takes 4 stage TM remote sensing image （1976,1989, 2000,2009） as the data source, and uses RS,GIS technology to analyze the land use characteristics of tempo- ral and spatial variation from 1976 to 2009. The research shows that：from the nineteen seventies up to now, the forest land, grassland and other land use proportion of Wuerhe District has gradually reduced,while the cultivated land and industrial land proportion has gradually increased, besides, the increased amount of resi- dents and roads is very small and the waters area changes greatly.
