【摘要】 对中国气象中心黑龙江省的28个国家级气象观测站点1971～2006年的气象资料在GIS平台上进行分析,取1971～2006年36年间每10年平均积温变化和旬平均温度变化与大豆温度适宜度为指标体系,分析黑龙江省近36年变化特点及趋势,对目前黑龙江省大豆种植区划进行修正。分析表明,黑龙江省≥10℃年平均活动积温1971～2006年呈显著上升,与20世纪70年代相比,进入21世纪后,28个站点的≥10℃年平均活动积温增加100～350℃,最高增加近400℃,以松嫩平原和三江平原地区变化幅度较大,漠河等大兴安岭地区变化幅度较小。对于目前现行的黑龙江省农作物种植区划来讲,平均每个积温带年活动积温水平将向上增加1～1.5个积温带水平。更多还原

【Abstract】 Meteorological data obtained from 28 national meteorological observation stations in Heilongjiang Province of China Meteorological Center from 1971 to 2006 were used to analyze changes of accumulated temperature and ecological suitability of soybean on GIS platform.The results showed that the average ≥ 10℃ accumulated temperature from 1971 to 2006 significantly increased in Heilongjiang Province.Especially it increased 100~350℃(max.400℃)in the 21 Century from the level of the 1970s.The Songnen Plain and the Sanjiang Plain changed to a larger extent while the Daxinganling area including Mohe to a smaller extent.The level of the average annual accumulated temperature will increase by 1-1.5 accumulated temperature zone.更多还原
