RS与GIS支持下的土地利用及植被覆盖变化研究

Study on changes of land use and land cover based on RS and GIS technology

    摘要
  • 摘要: 利用遥感(RS)和地理信息系统(GIS)技术，对泰国北部山区1985～1995年土地利用及植被覆盖变化进行了定量研究，并以Mae Uam 子流域为例研究了各类用地的地形分布状况及其变化趋势。结果表明，10年间流域内森林面积减少，而耕地、裸地、草地和城镇建设用地增加且这些变化主要发生在地势较为平坦的地形范围内，在高坡度地区土地利用变化较小。

     

    Abstract: Based on RS and GIS technology, the land use and land cover are classified to six types,and their changes and distribution from 1985 to 1990 and from 1990 to 1995 in mountainous area,Northen Thailand are analyzed. The results show that forest area is declined dramatically,but area of farmland,grassland, bareland and town increased. The change tendency is from forest to farmland,grassland and town. Most of the changes occur in flat area.
