摘    要:以1961—2000年的气象资料为数据基础,采用FAO 1998年推荐使用的Penman—Monteith模型和参考作物法,对黄河流域不同类型旱农地区主要农作物的降水盈亏格局进行了分析。结果表明:黄河流域大部分地区冬小麦全生育期多年平均缺水量在250~500mm,且由南向北缺水量有依次递增的趋势,主要反映了冬小麦全生育期降水量与需水量的双重影响;夏玉米全生育期缺水量较多的地区为陕西省关中地区,约为200mm左右,由此向东缺水量值逐渐减少;春小麦全生育期多年平均缺水量基本上是从南向北逐渐升高,缺水量在200—500mm,显然是受降雨与需水两方面的双重影响;春玉米全生育期多年平均缺水量分布则是从南部向北部递增,亏缺量在0~400mm。

关 键 词:农作物水分需求  降水  格局  黄河流域

Abstract:Based on the data of 85 meteorological stations from 1961 to 2000 in Yellow River Basin, water requirements of main crops were calculated by using the Penman-Monteith model of FAO nominated in 1998 and consulting crop method. Results showed that the water deficit of winter wheat varied from 250 mm to 500 mm during the whole growing period, while it gradually increased from the south to the north of the region. The maximum water deficit of summer maize during growing period was with 200 mm occurred in the Guanzhong Plain, Shaanxi Province and reduced gradually to the east of the Yellow River Basin. The water deficit of spring wheat increased gradually from the south to the north with 200 mm to 500 ram, which was mostly affected by the rainfall. The water deficit of spring maize in the growing period varied from 0 mm to 400 mm, which increased gradually from the south to the north of the region.
Keywords:Crop water requirement  Rainfall  Pattern  Yellow River Basin
