摘要
河北省东南部黑龙港低平原区，水资源不足是这一地区农业生产的主要限制因素。但是由于降水分布极度不均，涝灾也时常发生。针对这一气候特点，在摸清四水转化规律和作物耗水规律的基础上，建立了一套与农田耗水相适应的、跨时空调节的农田抗（旱、涝）灾应变体系，为缓解水资源的不足开创了一条新路。
Inadequate resources of water is the principal contradiction of agricultural production in low champaign area of Heilonggang of east-southern Hebei province. But amount of precipitation is not uniform distribution in the area,so that waterlogging happens frequently. Directed against the characteristics of climate,after transformation of 4 kinds of water and law of water consumption of plants were understood, a set of resistance (drought, waterlogging) system which adapted with water consumption of farmland, regulated beyond time and space were set up. A new route was opened for mitigating inadequate resources of water.
