中文摘要：

采用肃北气象站1973-2010年地表温度和相关的气候要素实测资料,利用小波分析法等统计方法,分析戈壁过渡带地表温度对气候变化的响应特征.结果表明：近年来戈壁过渡带地表温度呈显著上升趋势,其中冬季上升0.85℃/10a,最为突出,春一秋季基本为0.19～0.45℃/10a;年平均地温在1986年前后发生了由冷向暖的突变.利用观测站平均气温、年日照时数、年平均蒸发量资料以及春季平均风速与地表温度建立关系模型,表明拟合所得的地表温度与观测值之间的误差分别在0～1.2,0～1.3,0～1.5,0～2.2的小范围内波动.这说明地表温度对平均气温、年日照时数、年平均蒸发量资料以及春季平均风速都存在响应,其中风速对地表温度的变化具有突出的响应特征,即地表温度与风速之间表现为风速增大地表温度上升,或风速减小地表温度降低的特征.

英文摘要：

Wavelet analysis and other statistical methods were used to analyze the surface temperature and climate related data from the Subei meteorological station from 1973 to 2010 and the results show that in recent years the surface temperature of the desert transition zone had a significant upward trend,especially in the winter,rising by 0.85℃/10a and presenting a the most prominent increase.Prom spring to winter changes were in the range of 0.19～0.45℃/10a.The average surface temperature changed suddenly from cold to warm in about 1986.Observed average temperatures,annual sunshine hours,average annual evaporation data as well as the spring average wind speed and surface temperature relationship model show that the error between the surface temperature and the measured values fluctuated between 0～1.2,0～1.3,0～1.5,0～2.2,indicating that the average surface temperature and sunshine hours,the average annual evaporation,the spring mean wind speed and temperature were all related to each other,i.e.changes of wind speed had a great influence on the change of surface temperature and there was a relationship between the surface temperature and wind speed：when the wind speed increased the surface temperature rose too,or when the wind speed was reduced the surface temperature also dropped.
