本文将地下水系统控制与作物种植系统相结合,建立以浅层地下水投入效益为目标,在水土资源等多种约束条件下咸淡水地区种植结构优化模型。该模型被用于确定河北省南皮县几个典型年份(1985,1990,1995,2000)种植结构优化方案。

In the salt-fresh water region an optimization planting structure model is developed by combinning the groundwater control system with the cropping system. The object of this model is to maximize the net benifit of the crop production under the restrictions of water, soil resource, and so on. This model has been applied to determine the schemes of the planting structure optimization in Nanpi County for the years 1985, 1990, 1995, and 2000.
