摘　　要：采集了宁夏灵武郝家桥镇四个剖面的土壤样品进行分析,研究该地区农田土壤全盐及分盐的空间分布特点。结果表明:电导法、烘干残渣法、离子求和法所得结果相关性较好;该地区农田土壤在不同地点,不同层次间变化显著,并且土壤盐分随深度增加而下降;不同地点同一层次间土壤盐分含量不一致;该采样区水溶性盐以硫酸盐为主。4 farmland soil profiles are analyzed at HaoJiaQiao town of Ningxia. The analyzing items include total salinity and salinity spatial distribution characteristic in this area. The results show that the mutuality between electric conductance meth- od and dry residue method is better. Soil salinity varies prominently among different places and different layers in this are- a. And Soil salinity decreases with deepness increasing. The content of sulphate is obviously high in sampling area.
