基于宁夏第五次土壤盐渍化调查数据，以宁夏沙坡头灌区为对象，分析高位灌区对低位灌区土壤盐渍化的影响，系统阐述地下水埋深、矿化度与土壤盐渍化的关系，得出：①南山台子扬水灌区对低位灌区的影响范围为350～550m，由高位灌区前沿向低位灌区延伸，土壤盐渍化程度由重变轻；②根据地下水埋深与土壤盐化模型分析结果，春灌前地下水埋深越小，土壤盐分积累越快，含盐量越大；③地下水矿化度的大小影响土壤盐渍化的程度，矿化度越大，土壤盐渍化程度越重。

Based on the data of soil salinization investigation in Ningxia Province and taking Shapotou irrigation area as an object,the paper ana-lyzed the influence of salinization of higher elevation irrigation area to the lower elevation irrigation area and discussed the relationship between sa-linity,depth of groundwater and soil salinization. The conclusions are that a)the Nanshantaizi pumping irrigation area impacts the low irrigation ar-ea,the range is 350 ~ 550 m,from high to low irrigation area extending direction,the soil salinization from heavy to light. b)As the result of model,before the spring irrigation,the shallower the groundwater depth is,the faster the soil salt accumulation and higher the salt content will be. c)The groundwater salinity affects the degree of soil salinization. The higher the salinity is,the more serious soil salinization will be.
