摘要
通过对银北灌区作物生长季节地下水埋深、矿化度和田间土壤全盐含量测定,分析了地下水的动态变化及春、秋季土壤盐分的分布特征,确定土壤盐分与地下水矿化度之间呈线性正相关,与地下水埋深呈对数负相关,并建立了相关方程。
Through measuring the groundwater buried depth, groundwater mineralization degree and total salt content in field soil during growing season of crops, the groundwater dynamic changes and the spatial distribution characteristics of soil salt content in Spring and Autumn were analyzed. The linear correlation between soil salt content and groundwater mineralization degree and the Logarithm relationship between soil salt content and groundwater buried depth were determined, and the dependent equation was established.
