| 摘 要： | 用线性趋势和单相关法分析了青海高原33个气象站的霜物候期及气象资料,结果表明:青海高原1978～2007年初霜、终霜变化趋势存在明显推迟、提早的区域性特征.在年代际尺度上,初霜大部分地区明显推迟,终霜大部分地区明显提早,无霜期绝大部分地区明显延长.少部分地区终霜对气温负相关显著,对降水正相关显著.部分地区初霜对气温正相...

| Abstract: | The frost phenophase was anaylysed with linear trend and single correlation method by using meteorological data from 33 weather stations in Qinghai Plateau.Results show that the variation trends of first frost and latest frost present regional features of delay and ahead of schedule,respectively.On the interdecadal scale,first frost was delayed while latest frost was advanced and frost-free period was extended obviously in most regions.In a few areas,a negative correlation existed between latest frost with ... |
