chinois. 运用线性回归插补途径和RHtest方法分别对1961-2010年我国东部林区853个站点的日最高气温资料进行插补和均一化检验订正,建立完整且均一的日最高气温数据集.在此基础上,对比分析我国东部林区近50年来最高气温订正前后的变化特征.结果表明：订正后东部林区年及四季（春、夏、秋、冬）平均最高气温每10年分别增加0.171,0.233,-0.002,0.201和0.263℃,订正后整个区域年平均最高气温均呈上升趋势,而订正前有部分站点呈降温趋势;春、秋、冬3季平均最高气温在整个林区几乎全部呈现上升趋势,夏季东部林区多数站点呈降温趋势,尤其是长江和黄河流域之间的区域。

By linear interpolation approach and RHtest procedure,a serially completed and homogeneous daily maximum temperature dataset of 853 meteorological stations during 1961-2010 in Eastern Forest Region （EFR） in China was established.Based on the dataset,an analysis on the change characteristics of the maximum temperature prior to and after adjustment was carried out.The results showed that the adjusted maximum temperature data series had an average warming trend of 0.171,0.233,-0.002,0.201 and 0.263 ℃ per 10 years on annual and four seasonal （spring,summer,autumn and winter） timescales,respectively.On annual scale,the adjusted annual maximum temperature all exhibited a warming trend,while the annual maximum temperature prior to adjustment had a cooling trend for several meteorological stations.Spring,autumn and winter showed a warming trend almost everywhere in EFR,while summer had a cooling trend in most stations,especially in the regions between Yangtze River and Yellow River within the EFR.
