摘　　要：介绍了我国岩溶地区石漠化旱地分布状况,从坡度、基岩裸露度、土层厚度及水土流失状况对石漠化旱地质量进行了评价与分析;同时,结合三期石漠化监测结果,分析了石漠化旱地面积、程度、演变趋势及水土流失动态变化状况与特点,依据国家生态工程及石漠化防治的实际需求,针对性提出了石漠化旱地保护利用对策,为国家与地方相关政策制订提供参考依据。Based on the 3rd rocky desertification monitoring, this paper introduced the distribution of rocky de- sertification dryland in Karst area of China, evaluated and analyzed the quality of rocky desertification dryland from the aspects of slope, exposure of bedrock, thickness of soil and soil erosion. Combined with the results of the 3rd rocky desertification monitoring, this paper analyzed the area, severity level, evolution trend and dy- namic change of soil and water loss of rocky desertification dryland. According to the actual demand of national ecological engineering and rocky desertification control, this paper also put forward some countermeasures for the conservation and utilization of rocky desertification dryland, which provided a reference for the state and lo- cal governments to formulate relevant policies.
