摘　　要：利用阿坝州九寨沟县1960~2018年站点资料、环境空气监测资料和MODIS/AQUA L3卫星数据产品中的归一化植被指数(NDVI),基于人体舒适度、度假气候指数与气候统计方法,分析了九寨沟县的旅游气候条件优势和环境空气质量,并提出了挖掘当地生态旅游气候资源的建议。结果表明:九寨沟年平均气温13.1℃;年平均降水量540.8 mm,小雨日数占降水总日数的73%且以夜雨为主;年日照时数为1670 h,光照充沛。该地干雨季分明,雨热资源配置优越;环境空气质量全年优良率达100%,适游期长;春秋温凉、夏无酷暑,人体舒适度6~8月最高,尤其适宜避暑旅游。未来应从挖掘天气天象景观、开发避暑旅游、立足区位优势打造生态气候品牌等方面,发挥当地气候资源优势,打造全域生态旅游智慧气象服务典范。The station data, environmental air quality data, and the normalized vegetation index (NDVI) from MODIS/AQUA L3 satellite data products in Jiuzhaigou County, Aba Prefecture from 1960 to 2018 were used in this research. Based on human comfort, vacation climate index and climate statistics, we analyzed the advantages of tourism climate conditions and ambient air quality in Jiuzhaigou County. In addition, we put forward suggestions to tap local eco-tourism climate resources. The results showed that the annual average temperature of Jiuzhaigou was 13.1˚C;the annual average precipitation was 540.8 mm, and the number of light rain days accounted for 73% of the total number of precipitation days, and night rains were the main ones;the annual sunshine hours were 1670 h, and the sunshine was abundant. The dry and rainy seasons in this area are distinct, with simultaneous rain and heat;the annual good rate of ambient air quality reaches 100%, and the suitable travel period is long. Jiuzhaigou County is cool in spring and autumn and comfortable in summer. Human body comfort is the highest in June to August, which is very suitable for summer travel. In the future, it is recommended to explore weather and astronomical landscapes, develop summer tourism, and use location advantages to build an eco-climate brand. Jiuzhaigou should give full play to its advantages in local climate resources and create a model of smart weather services for eco-tourism.
