人民胜利渠灌区在二十世纪五六十年代曾发生过严重的盐渍化问题，目前盐渍化由明转暗，利用ArcGIS软件，通过分析灌区中部地下水埋深与矿化度的丰枯水期分布特征及二者之间的响应关系，以期为了解灌区盐渍化风险和地下水位调控提供依据。结果表明，研究区枯水期浅层地下水埋深平均为4.42 m，矿化度平均为1.55 g/L；随着灌溉和降水入渗，丰水期浅层地下水埋深总体明显减小，平均值为3.77 m，矿化度总体也略有减小，平均值为1.38 g/L。从空间上看，灌区浅层地下水埋深自西北、西南向东南呈递增趋势；矿化度在灌区西北和东南较高，中间部分相应较低。从整个灌区来看，浅层地下水埋深与矿化度的空间分布趋势不一致。但从时间变化规律来看，矿化度随地下水埋深增大呈增加趋势，反之亦然。对灌区地下水埋深变化与矿化度变化之间的回归分析表明，二者具有一定的线性相关关系；地下水位每下降1 m，矿化度升高0.148 g/L，因此，从盐渍化风险来看，地下水水位控制应引起重视。
In the 1950s and 1960s, People’s Victory Canal irrigation district had experienced serious salinization problems. At present, salinization turned from light to dark. By using ArcGIS software, by analyzing the distribution of groundwater depth and salinity in the middle part of the irrigation area, Characteristics and the relationship between the two, with a view to providing information for understanding the risk of salinization and regulation of groundwater level in irrigation area. The results show that the average depth of shallow groundwater in dry season is 4.42 m and the average salinity is 1.55 g / L. With irrigation and precipitation infiltration, the depth of shallow groundwater in flood season decreases obviously, with an average of 3.77 m, overall salinity also decreased slightly, with an average of 1.38 g / L. From the perspective of space, the groundwater depth of shallow groundwater in irrigation area shows an increasing trend from northwest and southwest to southeast. The salinity is higher in the northwest and southeast of the irrigation area, while the middle part is correspondingly lower. From the perspective of the entire irrigation area, the spatial distribution of shallow groundwater depth and salinity is inconsistent. However, according to the law of time variation, the degree of salinity increases with the increase of groundwater depth, and vice versa. Regression analysis between the change of groundwater depth and the degree of salinity shows that there is a certain linear relationship between the groundwater level and groundwater level. When the groundwater level decreases by 1 m and the salinity increases by 0.148 g / L, Risk, groundwater level control should pay attention.
