本文以彭场基点实地观测实验的大量数据为依据,分析研究了江汉平原平原湖区农田地下水的动态变化规律,首次提出了平原湖区农田地下水与干支大排水沟水力联系不密切、而与田间小排水沟水力联系很密切的论点,从而得出治理平原湖区农田地下水的关键是开好田间排水沟的结论,并对田间排水沟渠的规格问题提出了初步方案. Based on a large amount of data from field observation experiments in Peng field, this paper analyzed and studied the dynamic changes of farmland groundwater in plain area of ​​Jianghan Plain. It was first proposed that the hydraulic connection between farmland groundwater and dry branch drainage channel in the plain lake area was not close, The conclusion is that the key to controlling the farmland groundwater in the plain lake is to draw the conclusion of the drainage ditches in the field and put forward the preliminary plan for the specifications of the field drainage ditches.
