气候变化对山西省旅游气候舒适度的影响分析

The Impact of Climate Change for Tourism Climate Comfort Degree in Shanxi Province

旅游气候舒适度对旅游者出行以及旅游地开展旅游活动都有着重要的影响.本文采用山西省气象站50年气象站的资料,对反映气候舒适度的两个指数温湿指数和风寒指数进行计算,并利用线性趋势分析方法,从年代、年际两个方面对山西省50年来4月、5月、9月及10月的温湿指数和风寒指数总体变化趋势和站点时空变化趋势进行了具体分析.结果表明:从气候适宜度的总体变化来看,山西省这4个月的温湿指数表现为上升的趋势,风寒指数表现为下降的趋势,都朝着人体感觉更加舒适的方向变化,且山西省的旅游适宜期总体上有延长的趋势;从空间变化趋势来看,得出了在山西省的西南—东北一线,即五台山、原平、太原、隰县、临汾等站点,温湿指数上升趋势明显,风寒指数下降趋势明显的结论,为山西省旅游资源开发及旅游活动组织开展提供了气象气候方面的科学依据.

Tourism climate comfort degree has an important impact on tourists travel as well as tourism activities. Based on the climate data of the last 50 years, tile temporal and spatial variations of tourism climate comfort degree of April, May, September and October in Shanxi province in the last 50 years are analyzed by the way of temperature humidity index （THI） and wind chill index （WCI） using linear-trend estimation method. Results showed that the THI had an increasing tendency with yearly and decade diver- sity, and the WCI had a decreasing tendency. That is to say, the change trend of THI and WCI are more comfortable, and the tourism suitable stage had a prolonged trend in Shanxi.
