摘要
利用黑龙江省78个气象站1971~2018年作物生长季内(5~9月)逐日降水资料,采用数理统计方法,分析了黑龙江省作物生长季及其各月降水的时空演变特征。结果表明:1971~2018年,研究区作物生长季(5~9月)降水量随时间总体呈增多趋势,5~8月降水与生长季同步震荡,9月呈减少趋势;分析期内,生长季及各月降水的空间分布总体存在中部多的态势,但略有差异,生长季、6月、8月为东西少、中部多,5月西部少、中东部多,7月西多东少,而9月经向分布特征不明显;生长季内各月降水量呈“抛物线”型分布,降水主要集中于6~8月,并以盛夏7月最为集中。
Based on daily precipitation data from 78 meteorological stations in Heilongjiang Province from May to September during 1971 to 2018,Temporal and spatial evolution characteristics of crop growth season and its monthly precipitation(from May to September)in Heilongjiang province was investigated by using the mathematical statistics methods.The results showed that the precipitation was generally increasing during the growing season of crops in the study area,and the trend of precipitation in May,June,July and August was the same as that in growth season,but the precipitation in September was decreasing.During the analysis period,there was a trend that the middle regions had more precipitation in growing season and every month,but spatial distribution of precipitation was slightly different.The precipitation in the growing season,June and August was less in East and West,and more in the middle,and the precipitation in May was less in West,and more in the middle regions and East,and the precipitation in July was less in East,and more in West,and the longitude distribution of precipitation in September was not obvious.The distribution of monthly precipitation during the growing season was parabola type,and precipitation mainly occurred in June to August during summer and was most concentrated in July.
