摘要:

以新疆石河子气象局1967~2006年年平均气温、降水量和无霜期观测资料为研究对象,运用线性拟合、3 a滑动平均和Mann—Kendall方法进行趋势和突变分析。结果表明:近40 a石河子年平均气温呈上升趋势,平均增温率达到0. 51 ℃/10 a,秋季增暖率较大,夏季和冬季增暖率较小;年降水量呈上升趋势,春季趋向于暖干,冬季趋向于暖湿;石河子气温突变时间是1988年,降水突变时间是1969年和1993年;受平均气温升高的影响,无霜期天数增加率为4. 74 d /10 a,近40 a共增加19 d。关键词:年平均气温;年降水量;无霜期;突变

关键词: 年平均气温, 年降水量, 无霜期, 突变

Abstract:

Based on the average annual temperature, annual p recip itation and no frost period data from ShiheziMeteorological Bureau during the period of 1967 - 2006, the climate trend was analyzed using linear fitting method, 3 - year smoothing average and M - K methods. The results show that: (1) in recent 40 years the average annual temperature increased by 0. 51 ℃/ 10 a. and the increase rate was larger in autumn, smaller in summer and winter; (2) the annual p recip itation increased also, the trend toward warm and dry in sp ring butwarm and wet in winter; (3) the abrup t change of temperature was in the year of 1988, and 1969, 1993 for p recip itation;(4) the days of no frost period incresed by 4. 74 d /10 a, and 19 days increased totally in recent 40 years.

Key words: average annual temperature, annual p recip itation, no frost period, abrup t change
