摘　　要：西藏高原土壤侵蚀营力多样,侵蚀类型复杂,其评价与动态监测方法一直为人们所关注,根据多年对西藏高原土壤侵蚀的调查研究,从西藏高原土壤侵蚀区域分布特征出发,提出西藏高原土壤侵蚀应划分为自然侵蚀区和人为加速侵蚀区,分别采用土壤侵蚀潜在危险及土壤侵蚀分类分级的评价体系。前者采用人机交互式遥感动态监测方法,后者采用土壤侵蚀因子数据库与土壤侵蚀模型法相结合进行动态监测。Many studies have been focused on the evaluation and monitoring of soil erosion on the Tibet Plateau due to the varied erosion agants and the complicated types. Based on investigation for several years, the paper resulted in the spatial distribution soil erosion characteristics. The Tibet Plateau should be divided into natural erosion region and acceleration erosion region induced by human activities. Correspondingly, two different systems were built to evaluate the effect of soil erosion. The potential risk should be assessed in the natural erosion using the method of human-computer interaction and the dynamic remote sensing datum. The gradation and classification system should be respectively used in the region influenced by human activities, The combination of factors database and model is used to monitor the change of soil erosion in this region.
