Facing to the reduction of the water diversion from the yellow river for hetao irrigation district inner mongolia autonomy, and giving attentin to agriculture production and improvement of salinization, this paper researches optimization model of district water - saving irrigation water management. the paper also quests for the optimization model of crop irrigation system and the optimization irrigation strategy aiming at the short of water for agriculture. in order to save water and use water high efficiently, this paper researches the change regulation of irrigation system of spring - wheat that is the important crop in the irrigation districted establishes the multidimensional dynamic model of irrigation rules of spring - wheat. lt also makes the simulation model of salt leaching of fall irrigation rules during non - growing period, and sorts the elements influencing water - saving of irrigation system
在內蒙古河套灌區的引黃水量減少又要兼顧灌區的農業生產和土壤鹽漬化向良性發展的形勢之下，本文針對灌區內區域灌溉水管理的現狀，對灌區內區域節水灌溉水管理優化模型進行了研究。研究針對農業水資源短缺的現狀，在節水灌溉條件下，對作物的灌溉制度進行優化模型探索，尋求最優灌溉策略。全文圍繞節水與高效用水，綜合應用了系統分析、灌溉排水及節水灌溉的原理和知識，研究了灌域內主要作物春小麥的灌溉制度的變化規律，建立了春小麥灌水制度的多維動態優化模型；建立了非生育期的秋澆制度的鹽分淋洗模擬模型；對節水灌溉水管理的影響因素的重要性進行了排序研究。 -
