摘要
本文介绍了两种适用于半干旱地区某次配水的优化模型,第1种以作物水分生产函数为基础,以全灌区净灌溉增产值最大为目标函数;第2种以某次灌水全灌区的水费收入最高为目标函数。这两种配水模型用陕西省洛惠渠灌区1989,1990年夏灌的实际用水资料进行了验证。可供各自流引水灌区在渠系水量调配中实际应用。
This paper introduces two kinds of optimal models of water allocation in a certain irrigation suitable to semiarid region. The first model is based on crop water production with the maximum net increased irrigation incomes for the objective function; the second takes the maxium of water fee benefits for a certain irrigation in a whole irrigation area for the objective function. These two water allocation models were verified by the actual water use data of luohuiqu Irrigation system and applied to the irrigation area by gravity for water allocation in canal systems.
