【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]:The traditional evaluation of tourism climate focuses on temperature and humidity index, cold index, determination of clothing index. Ignoring the risk of the plateau climate, it is difficult to make a comprehensive evaluation of tourism climate plateau. This paper introduces the plateau reaction risk and ultraviolet radiation intensity, the 99 city of Qinghai Tibet Plateau as samples, based on the climate data of 1980-2010 years. Dynamic analysis on the changes of each index. The conclusions are as follows: 1 the altitude is the main factor affecting the climate comfort and risks. The increase of altitude, temperature and humidity index, cold index decreased, increased risk of plateau reaction and ultraviolet radiation intensity; 2 climate comfort and risk was obviously different in different seasons. In summer, the temperature and humidity index. Cold comfort index is high, the risk of ultraviolet radiation, the risk of altitude sickness, in winter, spring and autumn season two belongs to the transitional season; 3 space, topography of the Qinghai Tibet Plateau, Comfort and risk has obvious regional differences, showing a "horseshoe shaped" distribution and change rule of "ladder". On this basis, the comfort and risk analysis of two-dimensional matrix, divided into 6 types. The study area for tourists to Tibet tourism timely, appropriate to provide guidance.
