摘　　要：主要讨论华北地区土壤中硫的分布及赋存特征．结果表明华北地区不同省市土壤中硫的含量有差异；土壤中硫的含量与土壤类型及成土母质等有一定关系．土壤中不同形态硫的含量结果表明，尽管该地区土壤中总硫在大部分土壤中含量较高，但植物有效硫的含量相对较低，土壤中的硫主要是以难溶无机硫和有机硫形式存在．The distribution and occurrence of sulfur in soil in Northern China were studied. The results obtained shows a difference in sulfur content among soils from various provinces and cities. There is also a significant correlation between sulfur content and soil type and soil parent material. The amount of available sulfur is much lower than the total sulfur which occurring primarily in insoluble inorganic sulfur or organic sulfur.
