摘要
利用1961-2013年气候资料,运用气候倾向率和Mann-Kendall检测方法对太仆寺旗区域气候变化特征进行分析,结果表明,年平均气温以0.34℃/10a的速度上升,冬季升温对气候变暖的贡献率最大,年降水量以2.1 mm/10a的速度下降,夏秋季降水量减少较明显。近53 a,除年降水量外,年平均气温、最高气温、最低气温、≥0℃积温和≥10℃积温等要素均发生了显著突变,但突变年份存在差异。
According to the climate data from 1961 to 2 013, using climate tendency rate and Mann-Kendall method, we analyzed the regional characteristic of climate in Taipusi banner. The results showed that the annual mean temperature had risen at the speed of 0.34 ℃ /10 a, the rising temperature in winter contributed to the climate warming and the annual precipitation decreased at the rate of 2.1 mm/10 a. During the summer and spring, the precipitation decrease was more noticeable in nearly 53 years. Besides the annual precipitation, other climatic element including annual mean temperature,annual maximum temperature, annual minimum temperature, the accumulated temperature（≥0℃） and the accumulated temperature（≥10℃） had abrupt a lot, but the abrupt time was different. The finding provided scientific basis for the local agriculture to adapt to the climate change.
