| 摘 要： | 基于黑龙江省30个气象观测站的农业气象观测资料,利用气候倾向率和累积距平法,分析了1980-2009年黑龙江省年均温和年降水量的时空变化特征,以期揭示黑龙江省近30a来的气候变化规律。结果表明:(1)黑龙江省年平均气温呈上升趋势,气候倾向率为0.55℃/10a,从季节来看,以冬季升温最快,其中又以1月份升温最快(0.86℃/10a);(2)年降水量表现为明显的减少趋势,其中夏、秋2个季节降水减少显著;(3)年均温增温幅度在空间上总体表现为南高北低的趋势;年降水量减少幅度大的区域主要分布在松嫩平原南部和三江平原北部的大部分地区。

| Abstract: | Based on the meteorological data of annual mean temperature and precipitation of 30 meteorological stations in Heilongjiang province in recent 30 years(from 1980 to 2009),this paper analyzed the temporal and spatial variations of annual mean temperature and precipitation in Heilongjiang province by using linear-trend estimation and the accumulative anomaly methods,so as to reveal the climate change characteristics of Heilongjiang province.The results showed that:(1) the annual mean temperature in Heilongjia... |
