Study on Climate Comfort Change of Bayanhot Tourism in Alxa League

选用阿拉善左旗气象观测站点1971—2020年共50年的温度、风速和相对湿度等气象资料,分别分析巴彦浩特年内和年际温湿指数、风寒指数,通过运用线性回归法研究了巴彦浩特近50年旅游气候舒适度变化。结果表明,巴彦浩特温湿指数年内呈现倒“V”字形分布特征,而风寒指数表现出“V”字形变化特征,年际变化均表现为冬季变化明显,夏季变化趋势较小;巴彦浩特适宜旅游时期为5—9月,而冬季为最不适宜旅游时期。

Using the meteorological data such as temperature, wind speed and relative humidity of alashan Left Banner meteorological observation station from 1971 to 2020, the annual and inter-annual temperature and humidity index and wind chill index of Bayanhot were analyzed respectively,and the change of tourism climate comfort in bayanhot in recent 50 years was studied by using linear regression method.The results showed that the bayanhot temperature and humidity index presents an inverted“V”type distribution within a year, while the wind chill index presents a“V”type variation.The inter-annual variation was obvious in winter, and the variation trend was small in summer. Bayanhot suitable tourism period was from May to September, and winter was the most unsuitable tourism period.
