内蒙古武川县土地利用类型布局变化分析

The Analysis of Land Use Types Layout Change In Wu Chuan County of Inner Mongolia

由于武川县8个乡镇的地理位置、地质地貌、水文、气候等自然条件的区域差异显著,经济发展与人口增长的速度不同,所以土地利用数量的变化还存在着区域间的差异。据单一土地利用类型相对变化率来反映土地利用数量变化的区域差异分析结果表明:1995-2005年间草地的区域变化差异最明显,其次是耕地、林地、水域,居民用地和未利用土地的区域变化不太明显。

This article is using two periods of TM images in 1995 and 2005, Because of obvious regional difference of geographical position, geology geomorphology, hydrology, climate ete natural conditions and different speed of economic development and population growth in eight township of Wu Chuan county,So there are the regional difference of change of land-use quantity. Using the relative rate of single land using types,which reflect the regional difference of change of land-use quantity. The result show that： between 1995 year and 2005 year, the regional difference of grassland is most obvious,then cultivated land,forest land, water, residential land, unused land is not obvious.
