摘要
为了改善畦灌的灌水效果,以汾东灌区北长寿的灌水试验为背景,基于Win SRFR软件模拟灌水质量的可靠性,以畦田长度L、单宽流量q和灌水时间t为灌水技术参数变量,分析其对灌水效果的影响,并通过Matlab进行了多元回归分析,建立了包括灌水效率Ea、储水效率Es和灌水均匀度Du在内的多目标优化模型。针对该模型存在的模糊性,将模型的目标函数模糊化,对该模型的优化求解进行了研究。根据模糊求解所获得的最优技术参数组合,利用Win SRFR软件模拟,对优化结果进行了分析。结果表明,该优化组合可以有效改善畦灌灌水效果,其优化求解方法可以合理优化灌水技术参数。
In order to improve the irrigation effect of border irrigation, using the irrigation experiment in Beichangshou of the eastern Fen river irrigation district as the background, based on the effectiveness of the Win- SRFR software for irrigation performance simulation, border length （L）, unit discharge （q） and the cutoff time（t） were used as irrigation technical parameters variables to analyze their influence on irrigation effect. The multiple regression analysis by Matlab was carried out to establish the multi-objective optimization model, including irri- gation application efficiency, distribution uniformity and storage efficiency. In view of the fuzziness existing in the model, the model of objective functions were made fuzzy, the optimization of the model solution was investi- gated. According to the fuzzy solution obtained by the optimal combination of technical parameters, using Win- SRFR software simulation, the optimization goal and simulation results were analyzed. Results showed that the optimum combination could improve the effect of border irrigation. Therefore, solving method is reasonable to optimize the irrigation technical parameters.
