Geologic Disaster Analysis And Risk Assessment Of Huangshan Senic Area And The Surrounding Areas

Geologic disaster of Huangshan Scenic Area and the surrounding areas causes not only the great impact of production and lives to local residents, but also great economic losses to the underdevelop region, or the negative impact to the unique tourism resources. The thesis have researched in this background. First of all, according to the research results, the topographical features and lithologic characteristics of this area have been known. The second, interpreted the development and frequency of landslide, slide, debris flow and other geological disasters in Huangshan Scenic Area and the surrounding areas with a detailed discussion of the causes and formation conditions that the geological disasters in this region occurred. Then to make the risk assessment to the area that in the region of prone to geological disasters, and describes a variety of geological disasters caused by the human engineering activities, and the prevention and controling of geological disasters. Finally, explained the status of geo-tourism resources in this district. Mainly obtained the following conclusions: 1. The spatial distribution of geological disasters have uneven and sub-cluster, 2. The distribution of geological disasters of Huangshan Scenic Area and the surrounding areas have been strictly controled by the combination of factors such as lithology, structure, topography, rainfall and human activities. However, in recent years, the effects of external factors which are the induction of geological disasters have become more and more obvious, human factors that controling geological disasters have increasingly become a major factor in the occurrence.
