人民胜利渠灌区水盐运动规律及评价

Motion Patterns of Water and Salt of Renminshengliqu Irrigated Area and Their Evaluation

系统总结了人民胜利渠灌区40年来水盐动态状况及水盐运动规律,并对灌区的水盐动态现状进行分析。结果表明:目前,无论地下水埋深还是地下水水质,都处在灌区开灌以来的最好时期;0～100cm土层土壤含盐量正在逐年减少,土体处在脱盐阶段。今后只要注意灌区水盐状况的调控和管理,就可避免土壤次生盐碱化的发生。

After summing up the behaviour and motion patterns of water and salt of Renminshengliqu Irrigated Area in 40 years and analysing the behaviour of water and salt of the irrigated area of the present condition, the author considers that at present, whether the depth or the quality of ground water have been all in their best period since starting the irrigation of the irrigated area; the salt content of 0～100 cm layer soil has been reducing year after year and the soil mass is in the stage of desalting.In the future, the secondary salinization can be avoided as long as the water and salt status of wasted area can be controlled and managed.
