摘    要:利用温湿指数、风寒指数、着衣指数、综合舒适指数及相关气候资料,对50年来东部5个典型城市旅游气候舒适度变化进行了分析和描述,分析其时空变化规律。结果显示:①50年来各城市旅游气候舒适度变化明显,北方城市各月温湿指数、风寒指数和着衣指数的变化幅度大于南方城市,纬度越高变化越大,纬度越低变化越小;②各月气候舒适指数变化存在较大差异,6月-9月温湿指数、风寒指数和着衣指数变化较小,1月、3月和10月-12月变化较大;③综合舒适指数以4月-5月、8月、10月和12月变化为最大,其它各月变化幅度较小,各城市气候舒适度变化形状变胖、谷变宽变深;④纬度较高的城市年综合舒适指数呈上升趋势,气候舒适期增长,促进旅游业的发展;纬度较低的城市年综合舒适指数呈下降趋势,气候舒适期缩短,抑制旅游业的发展。随着全球升温,气候舒适度呈下降趋势的城市将越来越多,对我国旅游业的抑制作用将越来越强。

关 键 词:城市  气候变化  气候舒适度  温湿指数  综合舒适指数

Abstract:The climate comfortable degree and its duration length play a fundamental role intourism development. It is also a major factor determining the length of the tourist period. Theclimate comfortable degree has changed significantly during the last 50 years because of climatechange. Based on climatic data of the last 50 years, variations of the tourism climate comfortdegree in five cities in the last 50 years in eastern China were examined in detail in terms of thetemperature-humidity index (THI), wind-chill index (WCI), Index of Clothing (ICL) andcomprehensive comfort index (CCI), with analyzing their spatial and temporal variations. Resultsshow that: 1) the tourism climate comfort degree has changed obviously during the last 50 years.THI, WCI, and ICL for each month in northern cities changed more significantly than in southerncities. The higher latitude the city is located in, the greater changes in the THI, WCI, and ICL of acity occur, vice versa; 2) variations in the climate comfort index for each month were different. TheTHI, WCI, and ICL for June, July, August, and September changed slightly during the study period,ranging from 2.68 to 7.02, 134.8 to 162.0, and 0.22 to 0.48, respectively. The THI, WCI, and ICLfor January, March, October, November, and December changed greatly, ranging from 11.52 to18.3, 307.3 to 613.1, and 0.55 to 0.89, respectively; 3) the CCI for April, May, August, October andDecember changed greatly, ranging from 2.6 to 7.8. The CCI for January, March, June, July,September and November changed insignificantly, ranging from 0.4 to 2.0. It was also found thatthere was no change observed for the CCI for February in the five cities under investigation; and 4)the CCI of a year will increase in cities located in higher latitude. Their climate comfortableperiods could thus last longer in comparison to other cities due to climate change. As such, thetourism for such cities could be enhanced. The CCI of a year will decrease in cities located in lowerlatitude, suggesting a shorter climate comfortable period, which would restrain their tourismdevelopment. As global warming continues, the climate comfortable period of more cities would beshortened, thereby inhibiting tourism development in China. Some mitigation actions shouldconsequently be taken to adapt this change to maintain stable and sustainable development oftourism. This study provides a basis for investigating the influence of climate change on tourismdevelopment.
