| 摘 要： | 随着未来气候变暖,我国东北三省农业生态环境可能发生较大的变化,其变化趋势为,热量条件变好,作物生育期延长,冷害频率降低,积雪期缩短,湿润条件变差,干旱频率增大,蒸发量增加。未来气候变暖,若平均气温升高2℃,那时东北三省粮食产量可增加36%左右,农业地带将大幅度地向北推移,并且提出相应的农业对策。

| Abstract: | Agroecological environment in Northeastern China could be greatly by affected the warming climate. Its variation tendency will be: 1) heat condition becoming favourable to crop growth, 2) growing period be lengthened, 3) frequency of cold damages be decreased, 4) period of snow accumulation be shortened, 5) humid condition becoming unfavourable to crop growth, and 6) drought frequency and evaporation be increased. If average temperature raises 2℃ caused by the warming climate, grain yield in Northeastern China will increase 36% or so, and agricultural zones will move greatly toward north. Thus, corresponding countermeasures must be adopted, |
