漳滏河灌区节水灌溉制度优化

Optimization of water saving irrigation in Zhang Fu river irrigation area

漳滏河灌区地下水超采严重,进行水资源合理配置刻不容缓。根据供水水源的现状对该灌区进行分区,采用水分生产函数的Jensen相对值模型,建立单一作物灌溉制度二维动态优化模型,对灌区灌溉制度进行优化。通过灌溉制度的优化达到节约水资源的目的,为缓和该区水资源短缺和作物生产之间的矛盾提供了方法。

As the grotmdwater has been overexploited seriously in the Zhang - Fu river irrigation area, it is urgent to achieve a rational resource allocation and optimize irrigation scheduling. This research divided the irrigation area into 3 parts according to the watersupply source, Jensen model was secleted as the moisture content production function, and the two - dimensional dynamic optimized model of sole crop irrigation scheduling were established. The way of saving water resources by optimizing irrigation scheduling is feasible to relieve the conflict between the shortage of water resources and crop production.
