利用惩罚最大T检验并结合元数据对重庆34个台站年平均气温资料进行了均一性检验和订正，结果表明该方法能够很好地应用于重庆年平均气温资料的均一性检验；重庆年平均气温资料的非均一性在空间上普遍存在，东北部最为明显；迁站是影响其非均一性的最重要的因素，仪器变动的影响也不容忽视；相较订正前，订正后重庆年平均气温资料的整体质量和连贯性明显要好，线性趋势空间分布更为合理，消除了个别台站线性趋势明显异常的情况；最后建立了建站至2010年重庆34个台站均一的年平均气温资料序列，为准确地评估气候变化趋势和变率奠定基础。

T he annual mean temperature data over 34 stations in Chongqing have been detected and adjusted by means of Penalized Maximal T Test and metadata .The results show that the method works well for homogeneity studies of the annual mean temperature over Chongqing .The nonhomogeneity of stations is widely found in Chongqing ,especially in the Northeast .The discontinuities usually result from the chan-ges in station location and changes in instrumentation are also important causes . Comparison analysis show s that the adjustment is reasonable and acceptable .T here are better quality and continuity for annual mean temperature w hich has been adjusted .T he distribution of linear trend for adjusted data is reasonable and several stations that have abnormal linear trend are eliminated .One of the important results is that the paper obtains the homogeneity data series of annual mean temperature from when the stations were build to 2010 .It is indispensable for a realistic and reliable assessment of historical climate trends and variability .
