| 摘 要： | 气温变化是气候变化背景下科学研究的热点问题。海河流域作为中国的粮食主产区,其气温的变化研究对于指导农业生产生活具有重要的意义。本文采用成熟的Mann_Kendall非参数检验方法对海河流域1957年-2008年的年平均气温、最高气温和最低气温的变化趋势进行了显著性检验,并采用滑动t-检验法对气温的突变期进行了分析,结果表明:海河流域年平均气温、最高气温、最低气温全部呈上升趋势,并且全区平均气温上升显著,东北部地区的最高和最低气温的上升趋势也全部通过显著性检验;各月平均气温中,1月、2月、3月、4月、9月气温上升显著。最低气温增温显著,邢台、蔚县和霸州等形成多个骤升中心,其中邢台最低气温最大变幅达0.78℃/10a;流域内大部分地区气温发生突变的年限多在1971年-1974年,1986年-1988年,1993年-1994年和1996年-1999年。气温突变主要发生在20世纪70年代和90年代,并且2月、3月份发生突变的范围最广。 |

| Abstract: | Detection of changes in air temperature receives much attention in the context of climate change.The Haihe River basin is a major grain production area of China.Investigating temperature change is of great significance for providing useful information to better manage agriculture water use.In this paper,trends in annual mean,maximum,and minimum temperatures over the period 1957-2008 in the Haihe River basin were detected using the Mann-Kendall non-parametric test method.Abrupt changing points were also dete... |
| Keywords: | Temperature trend Haihe River basin Mann-Kendall non-parametric test Point mutation |
