摘　　要：肩负粮食安全重要职责的黑龙江省,地处中高纬度,温度资源是限制该省农业生产的重要因素。≥10℃积温及积温带的变化,对农业品种布局、农业种植结构调整、产量形成都起着决定性作用。本研究采用1961−2020年黑龙江省31个国家气象站实测日平均气温、月平均气温和“基于城市化偏差订正的中国大陆月平均地面气温网格数据集”资料,进行了去城市化作用前后黑龙江省≥10℃积温对比分析。研究表明,与去城市化作用前相比,去城市化作用后近60a黑龙江省积温线性变化趋势和变化倾向率有所放缓;1991−2020年近30a积温平均值普遍降低,城市化作用导致的积温增量孙吴站超过200℃·d,呼玛、黑河、尚志、北安站超过100℃·d,其他大部地区在20~100℃·d;黑龙江省6条积温带中有5条因去城市化作用而调整,第一积温带范围大幅缩小,进而导致第二积温带范围显著增大,第三、四、五积温带有所南移。Heilongjiang province,with an important responsibility for food security,is in the middle-high latitudes.Thermal resource is an important factor restricting agricultural production in the province.Meanwhile its climate warming has been significantly higher than the national average in the past 60 years.Changes in thermal time and thermal time zones play decisive roles in the distribution of agricultural varieties,the adjustment of agricultural planting structure,and the formation of output.Using daily and monthly average temperature data of 31 national meteorological stations in Heilongjiang province from 1961 to 2020 and“Grid dataset of monthly average surface temperature in China's Mainland revised based on the urbanization deviation”,changes of thermal time above 10℃in Heilongjiang province before and after de-urbanization were analyzed.The results show that after removing the effects of urbanization,the linear change trend and rate of change tendency of thermal time from 1961 to 2020 have slowed down in Heilongjiang province.In the past 30 years during 1991 to 2020,the average thermal time generally decreased after de-urbanization.The increase thermal time caused by urbanization was below 100℃·d in most areas.The amount of Huma,Heihe,Shangzhi and Bei'an exceeds 100℃·d,and Sunwu exceeds 200℃·d.Five of six thermal time zones in Heilongjiang province were adjusted due to the removal of urbanization.The range of First Zone was greatly reduced,which led to a significant increase in Second Zone,and Third,Fourth,and Fifth Zones moved south.
