摘　　要：利用南宁市8个台站1960—2016年间的年平均气温和台站沿革资料,采用标准正态均一性检验(SNHT)方法对南宁地面观测站年平均气温资料均一性进行检验。结果表明:在显著性水平0.01时南宁站年平均气温资料在1999年出现间断点;台站迁移对气温资料均一性有直接的影响;气温资料均一性发生间断可能是周围环境变化、地理位置变化和高度变化的共同作用造成的。The homogeneity test of annual mean temperature series of Nanning weather station was carried out based on the method of standard normal homogeneity test(SNHT),using annual mean temperature dataset and the information of the meteorological station's historical evolution of 8 stations of Nanning City during 1960-2016.The results showed that a abrupt point in temperature series of Nanning weather station appearing in 1999 with the significance level was 0.01.The change of observation station location had a direct impact on temperature series.The specific reasons for the discontinuity of the homogeneity of the temperature data may be the interaction of the changes of the surrounding environment,the geographical position and the height.
