银川市主要旅游景区大风灾害风险区划

Wind Disaster Risk Zoning of Main Tourist Attractions in Yinchuan

选取距离银川市3A级及以上旅游景区较近的、数据质量较高的气象站点,通过筛选,最终确定银川市区域内2014—2020年1个国家气象观测站和30个区域气象自动站日极大风速资料作为基础分析资料,开展大风灾害风险区划研究。基于自然灾害风险四因子理论,建立大风灾害风险模型,计算大风灾害风险指数,并以此为指标,绘制银川市主要旅游景区大风灾害风险区划图。区划结果表明:贺兰山旅游景区和黄河外滩等沿黄景区大风灾害风险等级高,其他地区的旅游景区为中等风险及以下。根据大风灾害风险区划结果,对今后提前做好防御,减轻大风灾害对旅游资源和旅游基础设施等的影响,对更好地保障游客人身财产安全等具有重要的现实意义。

The high quality data of meteorological stations near the 3A level and above tourist attractions in Yinchuan City were selected,and the daily maximum wind speed data of one national meteorological observation station and 30 regional automatic meteorological stations in the region of Yinchuan City from 2014 to 2020 are finally determined as the basic analysis data to carry out the risk zoning study of gale disasters.Based on the four factor theory of natural disaster risk,a gale disaster risk model was established,the gale disaster risk index was calculated,and the gale disaster risk zoning map of major tourist attractions in Yinchuan City was drawn with this index.The zoning results showed that the risk level of gale disaster is high in Helan Mountain scenic spot,the Yellow River Bund and other scenic spots along the Yellow River,while the risk level of other scenic spots is medium and below.According to the results of gale disaster risk zoning,it is of great practical significance to take precautions in advance in the future,reduce the impact of gale disasters on tourism resources and tourism infrastructure,and better protect the safety of tourists’personal and property.
