| 摘 要： | 本文根据华北平原农田水分循环特点,建立了一个农田土壤水分平衡模型.利用研究区内30个气象台站20～40年的气象资料,模拟计算了华北平原主要农作物(冬小麦、夏玉米和棉花)的历年灌溉需水量.在模拟过程中,考虑到华北平原土壤质地层次排列复杂,土壤持水特性不一,将土壤的最大有效含水量划分了5个等级.根据统计排频分析,确定了在干旱年、中等年及湿润年型下冬小麦、夏玉米和棉花的灌溉需水量.并分析了华北平原的1m 土层土壤最大有效含水量为180～240mm 范围时,3种作物多年平均的及不同年型的灌溉需水量在华北平原的区域分布特征.

| Abstract: | Based on the character of the farmland water cycle in the North China Plain,a field soil water balance model has developed in this paper.With the meteorolog/cal data of 20 to 40 years for 30 dif- ferent climate stations in the Plain,the long-term annual irrigation water requirements (IWR) were simu- lated for winter wheat,maize and cotton.Considering the complex arrangement of soil texture profile and the various soil water conditions in the Plain,the soil available water were divided into five levels.Using... |
