| 摘 要： | 根据本溪地区1958~2009年气温序列资料,运用线性回归和Mann-Kendall法,对近52年来本溪地区年和季平均气温变化特征和突变进行了分析。结果表明,近52年来本溪地区气温以增温为主,冬季增温趋势最为显著;以1988年为界,可将本溪地区分为2个阶段：1958~1988年为相对冷期,1989~2009年为相对暖期;本溪地区年和季平均气温均在20世纪80年代末发生了突变。

| Abstract: | Based on the temperature sequence data in Benxi areas during 1958-2009,and through using the methods of linear regression and Mann-Kandell method,the mutation and change characters of temperature in Benxi areas in recent 52 years were analyzed.The results showed that the temperature in Benxi areas in recent 52 years showed the decreasing trend,especially in winter;1988 was viewed as the dividing line,Benxi areas were divided into two stages:1958-1988 were relative cold years,1989-2009 were relative warm years;the annual and seasonal average temperature in Benxi areas changed suddenly at the end of the 1980s. |
