土地开发整理中低压管灌的供需水量平衡分析

Land development and consolidation in low-pressure pipe irrigation water balance analysis of supply and demand

以河南某平原区土地开发整理工程的井灌区为例开展供需水量平衡分析,利用水文、地质、气象资料等,分别对项目区供水量、需水量进行测算分析,得到总供水量和需水量,从而对项目区供需水量进行平衡分析,得到项目管灌系统规划的区域有灌溉保证,不会引起地下水超采的结论。

The combination of He＇nan some plain land consolidation works well irrigation for example to carry out an analysis of the water balance of supply and demand,hydrology,geology,meteorology,etc.,on the project area of water supply,water demand analysis,the calculation of the total water supply and water demand.So the project area and demand analysis of water balance,resulting in project pipeline system planning area have irrigation that do not cause groundwater conclusion.
