黑龙江省黑土区近50年来四季气温时空变化特征分析
Spatiotemporal Variations of Air Temperature over the Last 50 Years in Black Soil Area of Heilongjiang Province
摘要
Abstract
Based on daily temperature data at 24 meteorological stations from 1961 to 2010 in black soil area of Heilongjiang Province,spatiotemporal variations of seasonal temperature change were analyzed with methods of spatial interpolation and a linear trend analysis.Under the condition of global warming,it showed that the annual mounting trend of air temperature in Heilongjiang Province was quite similar in the range of space.They increased gradually from north to south and high temperature region moved to north.Seasonal differences were found in seasonal temperature in black soil area of Heilongjiang Province.In recent 50 years,the mean temperature tended to rise obviously,especially in winter and spring with the former larger than the latter.The results showed that the largest contribution in mean temperature rising was winter.The maximum negative anomaly observed in winter of 1960s.The maximum positive anomaly observed in autumn of 1980s.关键词
