摘　　要：该文应用动态优化和线性规划方法分别建立了灌区单一作物的基于Jensen和B lank水分生产函数的非充分灌溉制度优化模型。在模型求解过程中,根据网络技术的原理,选择TCP/IP协议组建网络,采用传统的C/S(C lien t/Server)二层架构,运用A SP技术,使用VBScript、V isua l B as ic 6.0等语言编程,实现了网上灌区单一作物灌溉制度的实时优化计算。其计算方法为网上通用的应用程序,不受地域和时间等的限制,可节约人力、物力资源。In this paper, the proposed optimization model based on theories of deficit irrigation and network technology is applied to optimize deficit irrigation schedule of single crop. In order to apply the model, linear programming and dynamic programming methods were used, the technologies of TCP/IP, Client/Server model, ASP （Active Server Page） and the programming languages of VBScript, Visual Basic 6. 0 were selected. The result provides a approach to real-time computation of deficit irrigation schedule optimization. The web-based method is a general program, which provides a feasible program for saving human and material resources.
