| 摘 要： | 通过在安徽淮北平原的大田原型试验,分析了利用农田排水大沟进行控制蓄水的可行性及其对地表径流、地下水和土壤水的调控效果,提出了平原区依托大沟控制蓄水的农田水资源调控系统成套技术参数和模式。结果表明,单位长度大沟年调蓄水量为1.9×104m3/km左右,其影响范围内的农田地下水位较无控制大沟平均抬高约0.3~0.5 m,每年可增加作物对地下水的直接利用量50~80 mm,区域年农田水资源调控总量110 mm左右,约占当地年均降雨量的13%;只要控制合理、管理得当,不会因此而影响排水系统对农田涝渍的有效控制或降低原有排水工程的除涝降渍标准。以大沟控制蓄水进行农田水资源调控这一技术模式,是适合淮北平原区特点的解决水资源短缺和改善农田生态环境、调控区域水资源时空合理分布的有效途径。

| Abstract: | There are flooding,water logging and drought disasters in plaint area.But in the past,more attentions are paid on flooding,water logging control while less on drought.It is necessary to use the rainfall efficiently,regulate the farmland water resources so as to reduce the losses caused by drought and keep a good soil and water environment for crop cultivation.Base on the field experiments in Huaibei Plain of Anhui Province,this article analyzed the feasibility of water storage in main drainage canal and eff... |
