摘　　要：气候年景是一年气候状况的综合表征,主要由气温、降水描述,指数反映实际气候偏离气候平均水平的程度,指数计算方法由《气候年景评估方法》(GB/T 33670—2017)定义。结果表明:1980—2022年包头市气候年景指数在研究时段呈现波动上升趋势,不同等级气候年景随时间的变化大致呈对称分布。气温年景指数、降水年景指数、气候年景指数在研究时段均未出现明显突变。年平均气温在1997年前后出现突变,突变后气温增速变缓。Annual climate status is a comprehensive representation of annual climate conditions,mainly described by temperature and precipitation.The index reflects the degree to which the actual climate deviates from the average climate level.The index calculation method is defined by the“Assessment Method for Annual climate status”(GB/T 33670—2017).The results show that the annual climate index of Baotou City from 1980 to 2022 showed a fluctuating upward trend during the research period,and the changes of annual climate status at different levels over time were roughly symmetrically distributed.The annual temperature index,annual precipitation index,and annual climate index did not show significant changes during the study period.The annual average temperature experienced a sudden change around 1997,and after the change,the temperature growth rate slowed down.
