摘要
利用贵州省六盘水市2010年CBERS02B星影像,进行土地利用解译。采用基于栅格的GIS空间分析法进行土地利用综合适宜性评价,并对其进行分级评价。构建土地利用适宜性综合评价模型,并基于该模型以30 m×30 m栅格为评价单元,对研究区的土地适宜性进行综合评价。结果表明,研究区适宜开发的土地较少,只占研究区总面积的9.26%;受地形因素的影响,研究区大部分土地资源为适宜保护资源,不宜大规模开发和大量人口聚集。
2010 CBERS-02B Remote Sensing （RS） image of Liupanshui in Guizhou province was used to interpret land use information to analyzed and evaluated comprehensive suitability of land use by GIS spatial analysis based on raster and con- struct comprehensive evaluation model of land use suitability, which was then used to evaluate land suitability using 30 m^30 m grid as the evaluation unit. The results showed that land suitable for development in the study area was less, accounting for only 9.26% of the total area. Most land resources in the studied area were suitable for protection; and because of affect- ing by topographic factors, they were not suitable for large-scale development and gathering large number of people.
