%X The characteristics on ecological sensitivity of ecological function zones were analyzed based on Yunnan ecological function regionalization in this paper. The results indicate that soil erosion was serious in the east of Yunnan. In this area, moderate and more sensitivity of rocky desertification exceeded 50%. For the reasons of natural and geographical factors, such as the concentration of purple soil in limestone region, the sensitivity of soil erosion was higher in the majority of southwestern and part of southeastern Yunnan. The zone of sensitive habitat in Yunnan Province, mostly located on the ecotone, had high species richness and fragile habitats, which are difficult to restore once they are damaged. The improvement of land utilization, enhancement of agricultural production technology, control of agricultural pollution and development of ecological restoration are the critical means of increasing forest coverage, reducing the risk of soil erosion and mudslide and preventing the aggravation of rocky desertification.
