【摘要】 鉴于传统的喷灌工程规划设计方法所需周期较长、计算过程烦琐等缺点，本文提出建立喷灌工程规划设计决策支持系统。该系统以水利部颁发的《喷灌工程技术规范》(GBJ85-85)为准绳，总结了江苏各地节水灌溉示范项目多年来的实践经验，并充分融入了节水灌溉专家、学者的意见，应用Microsoft公司的Visual Basic语言开发而成。该系统采用Visual Basic作为系统开发平台，利用Visual Basic软件界面友好、功能强大、稳定性好的优点，同时，充分发挥Matlab软件的优化求解功能、AutoCAD的绘图功能、Excel的计算功能以及Word的文字处理功能，实现了多系统联合调度的智能系统，从而使喷灌工程的规划设计更加规范化和科学化。在该系统的帮助下，用户通过简单的人机对话，即可完成规划设计全过程，同时，系统可自动生成设计说明书、规划布置图、设备及概算表，大大提高了工作效率。 此外，本文尝试以人工神经网络的Hopfield模型对喷灌管网进行优化计算，取得了良好的效果。更多还原

【Abstract】 Because of the customary planning and designing of sprinkler irrigation spending too much time and calculating difficultly, the thesis pose building the Decision Support System of the planning and designing of sprinkler irrigation. This system is on the basis of "The Standard of Sprinkler Irrigation" .It has summarized the practice of water-saving irrigation in Jiangsu recently and has listened to many experts and scholars of water-saving irrigation. This system is built by Visual Basic. With friendly surface and powerful function of Visual Basic, optimization function of Matlab, automation-drawing function of AutoCAD, calculation function of Excel and word-dealing function of Word, it realizes the wisdom system of many software. With the help of this system, the user can complete the planning and designing of sprinkler irrigation easily. And the system can give a planning and designing drawing, a sheet of equipment and budgetary estimate. The user will work more efficiently with it.In addition, the thesis poses that the pipeline of sprinkler irrigation can be optimized by using the Hopfield Model of Artificial Neural Networks. And it has achieved good results in this way.更多还原
