摘要
提出一种全新的灌区设计方法， 即以农业用水量为依据， 以水盐平衡为条件， 考虑全灌区用水的灌溉设计方法。该方法所计算灌区引用水量， 比现状灌区实际用水量减少１０％ ～２０％ ， 且可通过灌区排水达到消除盐碱化的目的。针对典型灌区， 应用新方法进行了全区域的灌溉制度设计， 其成果可用于渠井结合型灌区设计及旧灌区改造。
This paper advances a kind of completely new method for designing irrigation district, that is, this irrigation design method is based on agricultural water use and with the salt water balance as the conditions to take into account water use in the whole irrigation district. The diverted water use calculated by this method in the irrigation district is reduced by 10%～20% in comparison with the existing water use in the irrigation district so as to achieve the objective of eliminating alkali salinization via the drainage in the irrigation district. With an aim at the typical irrigation district the irrigation system for the whole region is designed, whose research achievements can be used in the design of irrigation district of combining canals with wells as well as the improvement of old irrigation district.
