1961—2015年贵州省夏季旅游气候舒适度评价

Evaluation of Tourism Climate Comfort in Summer in Guizhou Province During 1961-2015

基于1961—2015年贵州省81个气象观测站的逐日气温、相对湿度、平均风速和日照时数等资料,分析了贵州省夏季各月的温湿指数、风效指数、穿衣指数及旅游气候舒适度的时空分布特征。结果表明:6月温湿指数和风效指数为夏季最低值,7月和8月温湿指数、风效指数和穿衣指数的年际变化基本一致,其中6月第1候和第2候是贵州省夏季最舒适的候;空间分布上,夏季温湿指数和风效指数整体上自西向东呈递增趋势,而穿衣指数由西向东呈递减趋势;舒适度空间分布表明,6月是贵州省夏季旅游的最佳月份,6月仅贵州省南部低海拔地区处于"较不舒适"等级,大部分地区处于"较舒适、舒适"等级,7月和8月"舒适"区域主要位于贵州省西部地区。

Tourism comfort degree is an important factor which impacts the human settle environment and tourism resources evaluation.Based on the daily air temperature,relative humidity,mean wind speed,sunshine hours and other meteorological observations of 81 meteorological stations in Guizhou Province during 1961-2015,the spatial and temporal distribution characteristics of the temperature and humidity index（ THI）,wind chill index（ K）,index of clothing（ ICL）,and tourism climate comfort index（ Z） in Guizhou Province were analyzed. The results show that the THI and the K were minimum in June,relatively high in July and August,while the first pentad and the second pentad of June was most comfortable in summer in Guizhou Province. For spatial distribution,the THI and K showed an increasing trend from west to east,but the ICL presented the opposite trend. The spatial distribution of comprehensive tourism climate comfort degree showed that the most comfortable period of tourism was June in Guizhou Province. However,in July and August ＂comfort＂region was mainly located in the western region of Guizhou Province.
