摘　　要：该文根据 1 998年 6～ 1 0月上旬在拉萨地区进行的臭氧总量及臭氧垂直廓线的观测结果 ,并结合同期同纬度其他两个臭氧站数据资料 ,证实了以拉萨地区为代表的青藏高原在夏季存在“臭氧低谷”的现象 .分析表明 ,地基和卫星观测的臭氧总量有一定误差 .Umkehr观测反演结果表明夏季拉萨地区平流层臭氧分布和同纬度其他地区相比略有不同 ;在对流层 。An observational study on total ozone amount and its vertical profile is presented using the measurements taken in Lhasa in the summer of 1998. In combination with other data sets, it is proved that there is a natural 'ozone valley' over the Tibetan Plateau. Analyses show that there are errors on total ozone amount between ground based and satellite ozone measurements. Brewer Umkehr observations demonstrate that the layer with maximum amount of ozone in the stratosphere over Lhasa may exist in altitude ranging from 25 km to 27.5 km in summer, with higher values and narrower width when compared with other regions in the same latitude. But the Umkehr measurements overestimated the tropospheric ozone. Observations of ECC ozonesondes show that there has obvious lower amount of ozone in the troposphere over Lhasa in the summer season.
