调整作物种植结构，优化井渠用水比例，合理开发利用地下水，是灌区水资源高效利用的有效途径。以地下水均衡为基础，以月时间尺度动态模拟地下水埋深变化，并将其对应的灌溉水量作为生态约束条件，建立多目标种植结构优化模型，选择人民胜利渠灌区为例进行模拟分析。在考虑地下水均衡的基础上，调整地下水埋深于合理状态以追求更好的生态效益，优化种植结构减少总用水量以达到更高的社会效益，提升灌区经济净收益以获取更大的经济效益，从而实现灌区综合效益最大化。经模型调整，各月地下水均于合理状态，并提升灌区净收益7．36％，减少灌溉需水量2．77％。结果表明，该模型的构建是合理、可行的，其对新型生态农业发展具有一定的理论意义和实用价值。
調整作物種植結構，優化井渠用水比例，閤理開髮利用地下水，是灌區水資源高效利用的有效途徑。以地下水均衡為基礎，以月時間呎度動態模擬地下水埋深變化，併將其對應的灌溉水量作為生態約束條件，建立多目標種植結構優化模型，選擇人民勝利渠灌區為例進行模擬分析。在攷慮地下水均衡的基礎上，調整地下水埋深于閤理狀態以追求更好的生態效益，優化種植結構減少總用水量以達到更高的社會效益，提升灌區經濟淨收益以穫取更大的經濟效益，從而實現灌區綜閤效益最大化。經模型調整，各月地下水均于閤理狀態，併提升灌區淨收益7．36％，減少灌溉需水量2．77％。結果錶明，該模型的構建是閤理、可行的，其對新型生態農業髮展具有一定的理論意義和實用價值。

Adjusting crop planting structures ,optimizing the ratio of water drainage wells and the exploiting of groundwater irrigation rationally are effective ways to efficiently use water resources .Groundwater balance ,which is based on a monthly time scale dynamic simulation of groundwater depth changes and the corresponding irrigation water as ecological constraints ,is considered to establish the multi-objective optimization model for planting structures and the People Victory Canal is selected to simulate research .In con‐sidering groundwater balance ,based on the adjustment of groundwater depth in a reasonable state to achieve better eco-efficiency , optimizing planting structures ,to reduce the total amount of water in order to achieve higher social benefits ,the overall economic ir‐rigation is improved to achieve greater economic benefits .After adjustment ,average groundwater level is in a reasonable state in each month ,with 7 .36% of net economic improving in irrigation and 2 .77% reduction in irrigation water demand .The result shows that this model is reasonable and feasible ,it has some theoretical significance and practical value of the new eco-agricultural development .
