摘要
根据干旱地区实测的田间土壤含盐量、地下水埋深和矿化度以及灌溉量 ,分析了土壤盐分的时间动态变化及空间分布特征 ,确定了土壤盐分与地下水矿化度的线性正相关关系 ,建立了土壤盐分与地下水埋深和矿化度的统计模型。
The temporal dynamic changes and spatial distribution characteristics of soil salt content are analyzed according to the field soil contents, groundwater buried depth, and quantity of irrigation water observed in the arid areas. The linear correlation between soil salt content and groundwater mineralization degree is determined, and the statistical model for the relation between soil salt content and groundwater buried depth, and groundwater mineralization degree is established.
