| 摘 要： | 运用遥感和地理信息系统等技术，通过坝上不同时期土地利用格局的动态监测，对20年来的农业水土资源变化进行了对比分析。结果表明，林地、草地面积的增加，使流域蓄水能力增强。影响土壤风蚀的主要因素是土地利用类型的变化，土地利用方式变化引起土壤理化性状有规律的改变，土壤退化正向着恢复逆转的方向发展。在不同的农业土地利用类型组合中，以坡梁草地-旱滩耕地-滩地水浇地-下湿滩天然草地的可持续性最佳。

| Abstract: | Evaluation and comparison of the water and soil resources change duaring 20 years of Bashang area was carried out with the aid of remote sensing and GIS and land use pattern monitored continuously. The results showed that main factor to influence soil erosion was the way of land use. The alteration of land use and land cover caused soil changes in physical and chemical properties regularly. The wind erosion and desert area was controlled effectively and desertification land developed adversely in Bashang area. Among the three land-use types studied, the combination of grassland on the hills-dry land in the river valleys-irrigated land in the river valleys-natural grassland in the wet river valleys, showed the best sustainability. |
