黄山风景区崩塌灾害危险性评估及防治对策

黄山风景区是集世界自然遗产、文化遗产和地质公园“三冠”于一体的海内外知名旅游风景区。然而,近年来频发的地质灾害特别是崩塌灾害已经严重影响到景区游客的生命和财产安全,并对景区周边的道路交通、生产生活设施和地方旅游经济发展产生负面影响。为此,利用边坡防范工程的相关统计方法,定量测度了黄山景区单体崩塌的稳定性;结合GIS栅格网络技术,对景区内划定的52个栅格单元内的大范围崩塌灾害稳定性和危害性进行耦合分析。结果显示:崩塌单体不稳定,危险性大;整个景区崩塌灾害在空间分布上存在高易发区、中易发区和低易发区三个区间,并呈现出不同的崩塌灾害特征。在此基础上,针对每一区间提出不同的崩塌灾害防治策略,从而为黄山等类似风景区的灾害防治提供参考借鉴。

Research on the risk assessment and prevent to collapse disaster in Huangshan scenic area

Due to the frequent occurrences of geological disasters in recent years,Huangshan scenic area,World Natural&;Cultural Heritage and Geological Park,has seriously threatened not only the life and property safety of tourists,but also the traffic safety and living facilities or even the development of tourism industry.In order to avoid it,this paper,based on the slope prevention engineering statistical method and GIS grid network technology,makes coupled analysis on the stability and perniciousness of the monomer collapse and large-scale collapse disaster in 52 grid cells.The result shows that the whole scenic area could be divided into high-prone areas,moderate areas and low-prone areas with different collapse disaster features respectively.Based on the coupled analysis,this paper also puts forward some countermeasures for different areas,which will also be beneficial for some other scenic areas with similar threat
