| 摘 要： | 利用铜仁市6个气象站1970年～2010年月平均气温、年平均气温资料，采用线性拟合法、Mann-Kendall 突变检验法等方法对铜仁市近40年的气温变化特征进行分析。结果表明：1970年～2010年铜仁市的气温呈现明显的上升趋势，其中德江站增幅最高，松桃站增幅最低；通过Mann-Kendall分析，近40年铜仁市年平均气温出现突变，显著突变点在1998年。

| Abstract: | Using the data of the annual and monthly temperature on average from 6 weather stations in Tongren city, ranging from 1970 to 2010, we analyzed the climate trend rate of Tongren temperature variation for nearly 40 years by means of linear fitting and Mann-Kendall Mutation test. The results showed that Tongren city 1970-2010 annual temperature went upward clearly. Besides, Dejiang station had the highest increase and Songtao station had the lowest increase among these years. According to Mann-Kendall analysis, the average temperature mutated significantly in the past 40 years in Tongren city with the mutation point in 1998. |
