摘　　要：为实现小流域土地的可持续利用,以晋西南王家沟小流域为典型黄土丘陵区,借助GIS技术构建了流域土地栅格属性数据库,利用加权和叠加相结合的算法实施了区域土地适宜性评价。评价结果表明:王家沟小流域的土地利用差异性较大,高度宜农、高度宜林和高度宜牧的土地面积分别占小流域总面积的11.11%、70.04%和95.30%;对宜农地、宜林地、宜牧地较差的区域可经过适当的水土保持措施、营造水土保持林、种植灌木和土地改良等措施后进行规划使用。研究结果对小流域土地的可持续利用和区域生态环境的建设具有重要的实践意义。In order to achieve efficient land use in small watersheds,the Wangjiagou small watershed in the loess hilly area of southwestern Shanxi Province was taken as a typical research area.An attribute database of indicators such as watershed topography,land use types,and soil erosion intensity was constructed using GIS,and the land suitability evaluation of the small watershed was carried out using the weighted and superposition operation method.Research shows that there are significant differences in land use in the Wangjiagou small watershed,with land areas that are highly suitable for agriculture,forestry,and animal husbandry accounting for 11.11%,70.04%,and 95.30%,respectively;Areas that are suitable for agriculture and suitable for forestry and pastoral areas with poor quality can be planned for use after appropriate soil and water conservation measures,creating soil and water conservation forests,planting shrubs,and land improvement measures.This result has important practical significance for the sustainable use of local land and the improvement of ecological environment.
