本文对近30 a以来中国上空臭氧总量的时空动态变化特征进行遥感监测与分析。结果表明，中国上空的臭氧总量在持续下降，下降速度低于全球臭氧总量下降速度，而与北半球下降速度基本一致，略低于北半球下降速度。中国臭氧总量每年平均减少0.11%，大约下降0.36 DU，但2000年后中国臭氧总量下降的速度有所减缓,尤其是2005年以来，中国臭氧总量呈上升趋势，这与全球的臭氧总量变化趋势相同。中国臭氧总量的季节变化呈正弦曲线变化，最大和最小值分别出现在3月和10月，平均值大约分别为333.36 DU和284.54 DU。中国臭氧总量季节变化在纬度方向上不明显，而在经度方向上变化较大，同纬度地区臭氧总量，东部地区的大于西部地区的，南北方地区臭氧总量季节变化几乎呈相反的趋势。

This paper focuses on the temporal and spatial dynamics of total ozone over China from 1981 to 2010 with multi-resource remote sensing and ground-level monitors. The results indicate that the total ozone over Chi-na is continuously decreasing. The speed of the decreasing is slower compared with the whole world and keeps almost the same compared with the northern hemisphere, but it is slightly slower than that of the northern hemi-sphere. The total ozone declines by 0.11% per year, reaching 0.36 DU. However, the pace of the decreasing slowed down since 2000. The temporal distribution of the total ozone over China is uneven. The total ozone in-creases with the rise of latitude, and the total ozone of the eastern region is higher than the western region. The total ozone tended to increase from 2005. The seasonal variation of the total ozone in China indicates a sine curve and the maximum and the minimum values appear in March and October respectively, and their corre-sponding average values are about 333.36 DU and 284.54 DU respectively. The total ozone over China shows an obvious seasonal variation. Overall, the total ozone over China in winter and spring is higher than summer and autumn. In different seasons, the variations of the total ozone over China of the southern area and the northern ar-ea are not the same. In winter and spring, the variations of the total ozone over China of the southern area and the northern area are bigger. While in summer and autumn, the variations are not obvious. The seasonal change of the total ozone over China is not evident in the latitudinal direction, but in the longitudinal direction. The season-al variations of the southern area and the northern area are almost opposite. The amplitude of the seasonal varia-tion increases with respect to the latitude.
