喀斯特地貌景区的雷击风险分析——以云南石林为例

Analysis on Lightning Risk in Scenic Regions with Karst Landform——Taking the Stone Forest as an Example

旅游景区的雷电防护近年来逐渐被人们关注,但国内旅游景区的防雷状况不容乐观,景区雷击伤人事件时有发生,科学合理地采取有效措施对旅游景区进行防雷保护已显得刻不容缓。以云南石林为例,在对具有喀斯特地质地貌的石林风景区进行实地考察、资料查阅、数据采集、综合分析的基础上,研究讨论地形地质因素对雷暴活动的影响及景区存在的雷击风险,同时结合闪电数据,将雷击引起的生命损失分量及公共损失分量作为雷电灾害易损性评估指标,提出相应的雷电防护措施。

Lightning protection of scenic areas is concerned gradually in recent years,but its situation in China is not optimistic.Lightning injuries happen frequently in scenic areas,so scientific and rational lightning protection is needed urgently.Taking the Stone Forest scenic spot as an example,and according to the fieldwork,document investigation,data collection and comprehensive analysis,influences of topography and geological factors on lightning activities and lightning risks in scenic regions are discussed and studied.Life loss component and public component caused by lightings are selected as assessment indicators of lighting disaster vulnerability combined with lighting data,lightning protection measures are put forward accordingly.
