The Effection of the Climat Warming on the Adjusting of the Grain Construction in Hei Longjiang Province and the Strategies for the Agreculture in the Future 50 Years

在未来30、50年气温将增高1.9℃、2.4℃情景下,积温带向北推移近5个纬距,2050年,原第1积温带北移至大兴安岭北部,其余4个积温带基本消失。气候变暖将使黑龙江省主栽农作物水稻、小麦、玉米、大豆等种植区域和模式发生变化。因此提出了未来适应农业发展的6项对策,特别是主要作物结构调整及区域分布。

In the future 30 or 50 years if the temperature increases 1.9 centi gr eed or 2.4 centigreed, the accumulated temperature zone will move 5 latitudes to the north ,at 2050, the first accumulated temperature zone will be at the Da Xi ngan Ling Area, and the other foure accumulated temperature zones will be disapp eraed. Climat warming will cause the change of planting areas and models of rice 、soybeen 、wheat and graiz which were the main crops in Hei Longjiang Province .
