| 摘 要： | 利用1980~2019年若尔盖生态区内及周边共5个国家气象站逐日的气温、降水、风速、日照时数、相对湿度观测资料，以及2018~2019年葵花-8卫星AOD数据、MODIS卫星NDVI数据，对若尔盖生态区旅游气候资源和空气清新度进行了综合分析。结果表明:若尔盖生态区光能资源丰富，年平均日照时数达2128.2h；气温偏低，年均气温为5.5℃，各站月均气温为?9.3℃~22.6℃；平均年降雨量为685.6mm，干雨季分明，4~10月降水量占全年总降水量80%；年均相对湿度为65.7%，年均适宜湿度日数为287d；年均风速为1.9m/s，年均适宜风速日数为358d；若尔盖生态区空气清新指数RSAI全年均维持在较高水平，7月RASI值最高达到24.16，平均空气清新度全年皆在“较清新”及以上级别。该地区4~10月旅游气候资源相对最优，空气清新度达“非常清新”级，温度、湿度、风速适宜且日照充沛。夏季体感凉爽舒适、空气清新度高、最适宜开展避暑旅游活动。春秋偏凉，但大部分人仍可进行户外旅行，适逢开花季和红叶季前后，有利于挖掘物候景观资源。

| Abstract: | With the daily temperature, precipitation, wind speed, sunshine hours, and relative humidity of the five national meteorological stations around Ruoergai Ecological Zone from 1980 to 2019, as well as the AOD (Aerosol Optical Depth) data of the Sunflower-8 satellite and the NDVI data from the MODIS satellite data from 2018 to 2019, the tourism climate resources and air freshness in the research area were comprehensively analyzed. Ruoergai Ecological Zone is rich in sunlight resources, with an average annual sunshine time of 2128.2 hours. The annual average temperature is 5.5℃ which is relatively low, and the monthly average temperature of each station varies between ?9.3℃ to 22.6℃. The average annual rainfall is 685.6mm, and the dry and rainy season is distinct. The rainfall account from April to October is about 80% of the total annual rainfall. The annual average relative humidity is 65.7%, and the annual average comfortable humidity days are 287 days. The annual average wind speed is 1.9m/s, and the annual average comfortable wind speed days are 358 days. The air freshness index (RSAI) of the research area remains at a high level throughout the year, with the highest value of RASI reaching 24.16 in July. The air freshness of the ecological zone is at the level of “fresher” and above throughout all the year. The tourism climate resources are relatively optimal from April to October. The air freshness is at the level of “extremely high” while the temperature, humidity and wind speed are suitable and the sunshine is abundant during those months. The ecological area is cool and comfortable in summer, which is suitable for summer tourism. It is pleasantly cool in spring and autumn, but most people still could be able to withstand outdoor activities, which coincides with the flowering season and the red leaf season, is suitable to excavate phenological landscape resources. |
