海河平原区农田抗（旱涝）灾应变体系研究

A Study on Forming Anti-drought and Anti-flood System in Haihe Plain

摘要

摘要:海河平原区十年九旱，水资源不足是这一地区农业生产发展的主要限制因素。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，建立了一套与农田生态耗水相适应的跨流域调节的农田抗（旱涝）灾应变系统，为缓解水资源的不足开创了一条新路。

Abstract:Water shortage is the main limiting factor to agricultrual development in Hai-he Plain,But because the uneven distribution of annual precitpitation,water logging of ten occurrs.For solving this problem,a transregional anti-drought and flood adjustment system was set up based on the climatic characters and the patterns of crop water consumption.Then the capacity for anti-drought and anti-flood in this region was greatly increased.
