| 摘 要： | 传统的旅游气候评价着眼于温湿指数、风寒指数、衣着指数的测定。忽略了高原气候的风险性,难以对高原旅游气候做出全面性的评价。本文引入高原反应风险和紫外线辐射强度,以青藏高原99座城市为样本,依据1980-2010年气候观测数据,分析各指标的时空动态变化。结论如下:1海拔是气候舒适性与风险性的主要影响因素。海拔增加,温湿指数、风寒指数减小,高原反应风险和紫外线辐射强度增加;2气候舒适性与风险性具有明显的季节差异。夏季,温湿指数、风寒指数的舒适性高、紫外辐射的风险性大、高原反应的风险小,冬季相反,春秋两季属于过渡性季节;3空间上,受青藏高原的地形影响,气候舒适性与风险性具有明显的区域差异,呈现"马蹄状"分布和"阶梯式"递变规律。在此基础上,将舒适性与风险性进行二维矩阵组合分析,划分为6种类型区。本研究为游客适时、适地进藏旅游提供指导。

| Abstract: | Traditional assessments of climate comfort focus on the temperature humidity index (THI),wind-chill index(WCI)and index of clothing(ICL). If risk of the plateau climate is ignored,it is difficult to comprehensively evaluate the plateau tourism climate. We introduce the plateau response index(PRI),Quv,using a sample of 99 cities across the Qinghai-Tibet Plateau and long-term observation from 1980-2010,We analyzed changes in each factor across seasons and space and found that the main factor for climate comfort and risk on the Qinghai-Tibet Plateau is altitude. As altitude increases the THI and WCI decrease and the PRI and Quv increase. The THI, WCI and PRI are best in summer,spring and autumn alternate,and winter is the worst;Quv is the best in winter,followed by spring and autumn,and summer is the worst. Comfort and risk follow a regular horseshoe shape distribution and show step grading. A two-dimensional matrix portfolio of comfort and risk allows us to divide this into six types. For example,we found that high altitude equals uncomforTablele and high risk,and low altitude is the opposite. The best tourist area on the plateau is located at Qinghai Lake,Yarlung Zangbo River basin and along the edge of the plateau. This research offers an appropriate guide to tourists visiting the Qinghai-Tibet Plateau. |
