为了分析黑龙江省夏季季风的变化规律和夏季季风与年降水之间关系的变化,采用 Samel 发明的方法,用逐日降雨量数据计算每一年夏季季风到达、离开、停留在黑龙江省的时间.研究结果显示:在1960年至2000年间,黑龙江省的年降水量变化趋势是每10a增加2.229 mm,这一变化趋势不显著;夏季季风停留的时间和季风期间的降水量呈显著减少的趋势,分别为每10a减少6.9d和17.5 mm .夏季季风这一变化主要原因在于1960-1975 期间是夏季季风离开该省的时间提前,1990-2000年间是到达该省的时间拖后.夏季季风在过去40a的减弱使它对年降水量的贡献率每10a减少4.4%.图7表1参8

Precipitation in Heilongjiang Province of China increased slightly from 1960 to 2000. Adopting the method proposed by Arthur N. Samel, we separated monsoon rainband rain and calculated the initial and final date of monsoon rainband of each year and each station. For the period of 1960-2000, the change of annual precipitation in Heilongjiang Province, with an increasing trend of 2.229 mm per decade, is not significant; the duration and total monsoon rain decreased significantly, with a decreasing trend of -6.9 day per decade and -17.5 mm per decade separately. That change comes from early leaving date of summer monsoon rainband for the period of 1960-1975 and later arriving date of summer monsoon rainband for the period of 1990-2000. The weakening of summer monsoon makes its contribution to the annual precipitation decreased significantly, with a decreasing trend of 4.4 % per decade.
