| 摘 要： | 根据隰县1961年-2007年的气温资料，利用线性回归分析，结合年平均气温的五年滑动平均值变化趋势和平均气温年际变化趋势，分析了隰县年、季平均气温的变化特征，表明47年来隰县年平均气温有明显升高趋势；各季均以增温为主，春季增温尤其显著。通过Mann—Kendall突变分析对年平均气温进行突变检验，表明年平均气温于1985年发，毛突变，突变前后温差1．2℃，突变显著。

| Abstract: | Based on the temperature data from 1961 to 2007 in Xixian, the characteristics of annual and seasonal mean temperature variation was analyzed by using linear regression and combining with the five-year moving average trend and annual trend of temperature. The results showed that average temperature increased significantly in 47 years in Xixian. Average temperature increased in each season and average temperature increased more significantly in spring. By abrupt change analysis of Mann-Kendall, the average temperature was tested. It showed that annual average temperature has the abrupt change in 1985 and the temperature difference 1.2℃ in pre and post of abrupt change. The abrupt change was significant |
