滦河下游灌区生态作物优化布局与地下水调控

选择我国沿海灌区-滦河下游灌区,构建地下水模拟模型(GBM)和水资源优化配置模型(OPM),通过模型验证、模型耦合与优化控制计算,得出地下水的储蓄动态变量,合理调控地下水,得出土地优化利用和生态作物优化布局方案.结果显示,从2016年到2030年,地下水净储量恢复10万m3/a,地下水储量恢复79.2％.预测到2030...

Crop Pattern and Underground Regulation in Luanhe Irrigaiton Area

Based on Luanhe downstream irrigation area,the underground water simulation model(GBM)and optimum model were set up.Through model verification,model coupling and optimization control calculation,the groundwater dynamic variables,reasonable groundwater regulation,land optimal use and crop optimization layout scheme were achieved.The results show that from 2015 to 2030,the net groundwater storage would recover 10×10⁴ m³/years,which will recover to 79.2%.It is predicted that the groundwater drop will be basically restored by 2030.The results of crop optimization in the irrigation area show that the benefit of crop planting would be 3.33261 billion yuan by 2030.Compared with the traditional planting pattern,the total income from crop cultivation has more than doubled.The ecological environment,social and economic benefits are very remarkable.The research methods can be used as a reference for formulating agricultural water management strategies.
