摘要
以灌水均匀度、灌水效率为评价指标,利用SRFR406模型对5个改水成数、31个畦长及13个单宽流量进行灌水质量评价,研究畦灌的技术要素非劣解。结果表明,在实际灌水过程中,参照非劣解集,可随着畦长、可供流量等条件的变化灵活调整其他灌水技术要素,以满足灌水质量的要求,而优化灌水技术方案只能选择灌水技术要素的最优解。可见,在应用上,畦灌技术要素的非劣解优于最优解。
Irrigation uniformity and irrigation efficiency were used as the evaluating indexes to study noninferior solution of border irrigation technical parameters by using SRFR406 model to evaluate irrigation performances for 5 inflow cutoffs, 31 border length and 13 unit width inflows. The results showed that irrigation technical parameters could be adjusted flexibly to change border length and available inflow to meet the requirements of the irrigation quality referring to non-inferior solution, and the optimal solution could only be selected in optimization program of irrigation in the actual irrigation process. Therefore, the non-inferior solution is better than the optimal solution of border irrigation technical parameters.
