摘要: 积温是作物种植界限的重要参考依据, 分析其变化特征可为农业气候区划、合理种植农作物等提供科学依据. 基于黑龙江省62个气象站点1961-2014年的逐日平均气温资料和地理信息数据, 采用多种气候统计方法, 建立多元线性回归模型, 分析了近54年来黑龙江省≥10℃积温的时空变化特征.结果表明: 1961年以来, 黑龙江省≥10℃积温初日明显提前, 终日显著推迟, 持续日数增加,≥10℃ 积温显著上升, 在1994年发生突变;≥10℃积温随着纬度的增加逐渐降低, 随海拔的升高而减少, 低于1 900℃积温区域所占面积有逐年减少的趋势, 2 700℃以上积温区域所占面积呈显著增加趋势; 随着黑龙江省积温的增加, 积温带明显向北、向东移动, 第一和第二积温带面积显著增加, 第六积温带面积显著缩小.

Abstract: Based on the daily mean air temperature data from 62 meteorological stations in Heilongjiang Province and geographic information data, the spatial and temporal variations of active cumulated temperature of≥10℃ in Heilongjiang Province are analyzed by using climate tendency rate, cumulative anomaly and Mann Kendall test, multiple linear regression model of cumulated temperature space simulation method and GIS technology. The results show that from 1961 to 2014, the first day of the cumulated temperature of≥10℃ in the province had been significantly ahead of schedule, the last day had significantly delayed, accumulated temperature had showed a significant upward trend; a mutation occurred in 1994, followed by the cumulated temperature significantly increasing. The cumulated temperature decreases gradually with latitude and increases with altitude; the area of cumulated temperature below 1 900℃ shows a significant decreasing trend; area of cumulated temperature above 2 700℃ regions shows a significant increasing trend; with increase of cumulated temperature in Heilongjiang Province, cumulated temperature zones move northwards and eastwards obviously; area of the first and second cumulated temperature zones increase significantly, but that of the sixth one significantly decreases.

Key words: Heilongjiang Province, spatial simulation, cumulated temperature zone
