摘　　要：采用攀枝花1991—2020年30个气象站的观测资料和2017—2020年空气质量监测数据,计算无冬日指数、冬季空气优良日指数、避寒适宜日指数,综合分析避寒气候适宜度指数分布特征。结果表明:攀枝花冬季无冬日天数≥60d占63%,冬暖显著;四个国家站的冬季空气优良日数均值大于80d,攀枝花市环境空气质量良好;近30年攀枝花市避寒适宜日数均值为47d,避寒适宜日数与温度、日照、海拔高度密切相关;避寒气候适宜度指数≥60分占50%,攀枝花大部分地区很适合避寒,避寒气候适宜度指数较高的地区多位于攀枝花市中部地区。Based on the observation data of 30 meteorological stations in Panzhihua from 1991 to 2020 and the air quality monitoring data from 2017 to 2020,the index of non-winter day,the index of good winter air day and the index of cold avoidance suitable day were calculated,and the distribution characteristics of cold avoidance climate suitability index were comprehensively analyzed.Result shows that the non-winter day index more than 60d accounted for 63%in winter of Panzhihua,the winter was very warm.The average number of good winter air days at the four national stations was greater than 80d,and the ambient air quality in Panzhihua was good.In the past 30 years,the average number of cold avoidance suitable days was 47d,and it was closely related to temperature,sunshine hours and altitude.The cold avoidance climate index more than 60 points accounted for 50%,most of Panzhihua is suitable for cold avoidance,which mainly located in the middle areas of Panzhihua region.
