| 摘要: |
| 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。 |

| Abstract: |
| With the consideration of the synthetical effect of precipitation,irrigation and exploitation on groundwater dynamic regime in irrigation district,based on the thought of the separation well method,this paper,according to the intermittent characterstic of pumping water in irrigation district,has established and solved the corresponding mathematic model for adjusting and controlling groundwater dynamic regime with taking the period of pumping water and recovering water table as one calculating period,and also taking each calculating period for a dynamic process of continuation and feedback each other,we can realize adjusting and controlling calculation for groundwater dynamic regime of irrigation district with the use of this model. |
| Key words: irrigation district, groundwater dynamic regime,mathematic model |
