充分考虑降水、渠灌、井灌开采对灌区地下水动态的综合影响，根据隔离井法的思路，从灌区抽水具有间歇性的特点出发，将开采期－水位恢复期作为一个计算时段分别建立和求解地下水动态调控的数学模型，再将各计算时段看作是一个连续、互馈的动态过程，利用该模型便可实现灌区地下水动态的调控计算。 Considering the comprehensive effects of precipitation, canal irrigation and well irrigation on the groundwater dynamic in irrigation district, according to the idea of ​​isolated well method, taking the intermittent characteristics of pumping water in irrigation district, the recovery period of mining period and water level is set as a calculation period to establish and solve groundwater Dynamic control of the mathematical model, and then the calculation period as a continuous, mutual feedback of the dynamic process, the use of the model can be achieved in the regulation of groundwater irrigation regulation and control.
