摘要
采用气候统计学方法,对石河子4个站无霜期、初(终)霜日气候变化进行了分析,结果表明:石河子4个站历年初霜日推后,终霜日提前,无霜期延长,有利于农业生产。无霜期的绝对变率要比初(终)霜期的绝对变率大,年际差异相对较大,初霜期提早趋势均比终霜期提早趋势更为明显。
This paper analyzed variations and influences of the first/latest frost and frostless season of four stations in Shihezi by climate statistic method.The results revealed that the first frost postponed occurrence,the latest frost happened ahead,and frostless season was prolonged,which were advantage for agricultural production.The absolute variation rate of frostless season is greater than those of the first frost and the latest frost,and interannual difference of frostless season was greater comparatively.The ahead trend of the first frost was more evident than that of the latest frost.Finally,we put forward some defensive measures for against frost.
