阿坝州西北部气候变化特征及其对旅游舒适度的影响

Characteristics of Climate Change in Northwest of ABA Prefecture and the impact on Tourism Cli⁃mate Cornfort

选取阿坝州西北部1965—2019年气象统计数据,分析研究区域气候变化特征;运用温湿指数、风效指数和舒适度指数对阿坝州西北部旅游气候舒适度进行定量分析和评价。结果表明:阿坝州西北部近55年气温、降水呈上升趋势,相对湿度、年均风速、日照时数呈下降趋势;从旅游气候舒适度来讲,一年中阿坝县比若尔盖和红原县适合外出旅游的时间更长,且主要集中在6—8月;气温变暖、风速减小的趋势将使得旅游舒适度指数增加,延长旅游适宜期,有利于当地旅游业的发展。而日照时间的减少可能影响风效指数的降低,相对湿度的减小可能影响温湿指数的降低,这些均不利于旅游活动的开展。

This paper selects the meteorological statistical data of Northwest ABA Prefecture from 1965 to 2019,characteristics of climate change in the study area were analyzed.And then using temperature humidity index,wind efficiency index and comfort index,the tourism climate comfort in Northwest ABA Prefecture is quantitatively ana⁃lyzed and evaluated.The results showed that in recent 55 years,the temperature and precipitation in the northwest of ABA Prefecture showed an upward trend,but Relative humidity,average annual wind speed and sunshine hours showed a downward trend.In terms of tourism climate comfort,ABA county is more suitable for traveling than Zoige and Hongyuan county in a year,and mainly concentrated in June,July and August.The trend of temperature warm⁃ing and wind speed decreasing will increase the tourism comfort index,prolong the suitable period of local tourism,and be conducive to the development of local tourism.The decrease of sunshine time may affect the decrease of wind efficiency index,and the decrease of relative humidity may affect the decrease of temperature and humidity index,which are not conducive to the development of tourism activities.
