摘　　要：山地气候是气候变化响应研究的基础,气温垂直递减率是研究山地气候的重要指标之一。综合太白山最新高海拔区域站点以及4个低海拔气象站点的气象数据,研究太白山不同时间尺度气温垂直递减率,利用克里格空间插值法获得太白山25×25m的气温空间栅格数据集,并利用气象站点的实测数据对其进行验证,最终得出采用年均温的气温递减率计算出的结果误差最小,其次是夏季,由此确定太白山地区南北坡气温垂直递减率均为-0.5℃/100m。该结果是山地气候变化研究的基础,并可为其他山地气候研究提供参考。Mountain climate is one of the important researches on climate change response. Vertical lapse rate is the main characteristic of mountain climate. By collecting the daily temperature data of each altitude at Taibai Mountain, the rule of vertical lapse rate variation in the different periods was analyzed, then the vertical lapse rate was verified by using the space of kriging interpolation method. It is concluded that optimum temperature decline rate is 0.5℃ / 100 m in north and south slope of Taibai mountain area. Based on the decline rate, the tempera- ture spatial distribution change rate nearly 55 years and temperature change characteristics at high altitude were calculated by using Arcgis Kring method. It can be seen from the results, that the temperature changed obviously at the northwest and southeast of Taibai mountain. The temperature changed least at the most north area of Taibai mountains; the temperature at the central region of Taibai mountains had no obvious change. The temperature year by year in three different part was extracted at the high altitude area, as you can see from the trend of tem- perature change, the upward trend of temperature became more obvious from the late 1980s. In recent 20 years, the temperature had a significant rise overall in the Taibai mountains.
