青海湖流域自然环境对旅游安全的影响

The natural environment influence on tourism safety in Qinghai lake basin

青藏高原的旅游安全是目前国内旅游者和管理者高度关注的问题。以青海湖流域为研究对象,选取缺氧指数、太阳辐射、最大风速、冰雹日数、极端低温、综合自然灾害等指标,并应用GIS工具、数学模型及专家打分法对青海湖流域自然环境对旅游安全的影响进行了综合分析。结果表明:151景区、倒淌河景区自然环境对旅游安全的影响最小;沙岛景区、鸟岛景区及布哈河观光河段自然环境对旅游安全的影响较小;而金银滩草原等景区影响为中等,日月山景区等的影响相对较大;四周高山地区旅游安全的影响最大。因此,在做好青海湖地区旅游发展的同时,要重点保证游客在景区内开展各种旅游活动的安全。

Travel safety in the Qinghai-Tibet Plateau is one of the highly topical issue of domestic tourism activities. Qinghai Lake basin,lies in the northeastern part of the Qinghai-Tibet Plateau,is one of the scenic spots carrying out earliest tourism activities in the Tibetan Plateau. Based on GIS,a comprehensive analysis of the hypoxia index,solar radiation,maximum wind speed,hail days,extreme low temperature,natural disasters and other indeices were made with the application of mathematical models and the expert scoring method. The results and conclusions are as follows： natural environmental factors make a minimum impact on the safety of some scenic spots,such as Daotang river scenic,and 151 Scenic Spot; while the impact is relatively small in sand island scenic spot,Bird Island national Nature Reserve,Buha River reach in Tianjun etc.; Jinyintan prairie etc. are medium-impacted regions and the Riyue mountain scenic area etc. get a relatively large impact. In the high mountains area natural environment impacts the tourism safety at maximum. It is a emphasis to ensure the tourists safety when they carry out tourism activities in th scenic,while the tourism of Qingha Lake area is developed.
