摘要
根据精细灌溉的要求,采用零惯量模型和土壤入渗理论,开发建立了可进行畦灌水流运动模拟、灌水质量评价、灌水技术参数优化、利用灌溉试验资料率定糙率和入渗参数等功能的畦灌决策计算机服务系统,该系统可为灌区技术人员确定畦灌技术参数、指导灌水实践提供决策服务,也可作为科研人员研究节水灌溉的一种技术工具。
According to requirement of fine irrigation and based on zero-inertia equation ot water ttow over surface as well infiltration theory of water into soil,the article developed a decision serving system for border irrigation with fuctions of stimulaion of water flow over surface,evaluation of irrigation quality, optimization of irrigation parameters,calibration of maning roughness as well calibration of infiltration parameters using irrigation data. The system is a useful tool for manager to determin parameters in border irrigation and for researcher to study water-saving irrigation techniques.
