摘要:

从取水、输水、配水、排水系统的角度，构建了人民胜利渠灌区多水源循环转化模型，定量模拟分析了人民胜利渠灌区系统多年平均下的多水源循环转化关系。结果表明，从农田灌排系统角度，构建灌区多水源循环转化模型是可行的，能够较好地模拟灌区系统多水源循环转化过程；人民胜利渠灌区水资源的转化主要集中在输水和配水系统中，水资源转化量分别约为1.76亿和9.66亿m3，取水系统和排水系统水资源转化量较小，分别为0.01亿和0.13亿m3。输水系统中水资源转化以渗漏为主，渠系渗漏量约占总引黄水量的44%，这增加了引黄输水渠道沿线农田遭受渍害和土壤次生盐碱化的风险；配水系统中农田渗漏量约占水资源转化量的28%，这可能与部分地区仍采用落后的灌溉方式有关。

Abstract:

According to irrigation-drainage systems, the multi-water cycle and transformation model were established in accordance with the local specifications in the People's Victory Canal Irrigation District in this study. The average annual transforming relationships of multi-water resources were then simulated in the system of water intake, conveyance, distribution and drainage, successively. The results showed that the established model was feasible and could simulate the processes of multi-water cycle and transformation well. Water transformation mainly occurred in the water conveyance and distribution system, with 176 million and 966 million m3 water resources for transformation respectively. While only 1 million and 13 million m3 water resources were transferred in the water intake and drainage system respectively. It was found that leakage was the main way of water transformation in the water intake system, which could increase the risk of soil secondary salinization and waterlogging damage along the conveyance channels. Due to the backward irrigation modes, the farmland leakage accounted for 28% of water transformation in the water distribution system.
