近60年信阳市旅游气候舒适度变化特征分析

Change Characteristics of Tourism Climate Comfort in Xinyang During the Past 60 Years

  • 摘要: 利用1960—2019年两个国家级气象站的逐日平均气温、相对湿度、平均风速和日照时数等气象资料, 计算了信阳市温湿指数、风效指数、着衣指数和综合舒适指数, 进而分析其年际和季节变化特征。结果表明: 近60年来, 信阳市年均温湿指数、风效指数和着衣指数均向舒适等级方向发展, 并且3种指数均在春季表现出明显的向好趋势。综合舒适指数在年际上表现为舒适等级时长增加, 而不舒适等级时长减少; 在季节上表现为春季舒适等级时长增加, 而不舒适等级时长减少; 冬季较舒适等级时长增加, 而较不舒适等级时长减少。因此, 在当前全球变暖的气候背景下, 信阳市旅游气候舒适度正朝着更加舒适的方向发展, 且春季舒适性更强。信阳市应把握旅游气候资源优势, 开展更加丰富多样的旅游活动, 助力旅游业高质量发展。

     

    Abstract: Based on meteorological data such as daily average temperature, relative humidity, average wind speed and sunshine duration from two national level meteorological stations in Xinyang city from 1960 to 2019, using the temperature humidity index, wind effect index, clothing index and comprehensive comfort index, the interannual and seasonal variation characteristics of climate comfort in Xinyang city were analyzed. The results showed that, in the past 60 years, the annual temperature humidity index, wind effect index and clothing index in Xinyang city had all developed towards comfort level and all three indices had showed a clear upward trend in spring. The annual performance of the comprehensive comfort index showed that the duration of discomfort level and comfort level showed an opposite trend, with an increase in comfort level duration and a decrease in discomfort level duration. However, the duration of comfort level increased while the duration of discomfort level decreased in spring. The duration of secondary comfort level increased while the duration of secondary discomfort level decreased in winter. Therefore, in the context of climate change, the tourism climate comfort in Xinyang city was developing towards a more comfortable direction, and the comfort was stronger in spring. Xinyang city should take the advantages of tourism climate resources, carry out more diverse tourism activities, and then help the high-quality development of the tourism industry.
