摘要
本文计算了北京的可能蒸散量和农业需水量,并比较了农业需水量和水资源量的差额。结果表明,在一般年份,北京的水资源可以满足农业的需要,在少雨年份则有亏缺。北京目前农业节水潜力颇大,只要采取开源节流措施,充分挖掘潜力,即使在干旱少雨年份,也可以满足农业用水需要。
In this paper, the potential evapotranspiration and agricultural water demand are calculated, and the agricultural water demand is compared with water resources in Beijing. The results indicate that water resource can meet the requirement of agriculture in normal climatic years, although a deficiency would appear in drought years. At present, a higher potential could be found of water saving in agriculture over Beijing areas. If the potential is fully taken into account and the necessary measures are carefully adopted, the water could meet the requirement by agriculture even in drought years.
