【摘要】 针对丘陵山区集雨灌溉灌水定额小等特点,利用模糊数学方法,在田间试验的基础上建立了波涌沟灌的多目标模糊优化模型,并求得各灌水技术要素的优化组合:供水时间15 m in、停水时间15 m in和入沟流量1 L/s。采用该组合技术要素实际灌水试验证明:试验所得各灌水质量指标与模糊优化结果吻合较好,灌溉质量综合效果较好。研究结果为波涌沟灌技术要素的制定提供了多目标模糊优化组合方法,为广大丘陵山区小定额波涌沟灌技术要素的选择提供了多目标模糊优化模型及优化组合方案。更多还原

【Abstract】 In view of the small quota of irrigation by collected water, multi-objective fuzzy optimization model was established based on field experiment data and fuzzy modeling techniques.A combination of parameters for optimization of irrigation was gained by the solution of this model,i.e.in cycle of 15 minutes water supplying,15 minutes stopping and 1 L/s water flow rate of entering into furrow.It was shown that the irrigation quality indexes predicted by this model were close to those measured in the field experiment and that the comprehensive irrigation quality effect produced by these parameters was satisfactory.The results of this paper provide an effective irrigation plan for the surge irrigation area with small quota of irrigation water.Also,this paper provides an effective method for determination of technical parameters of surge irrigation.更多还原
