摘要
本文研究了海河流域各类植物硫元素含量特征及与土壤硫素的关系。结果表明：海河流域植物全硫含量平均值为０．２３２％，为正常含量的下限值，与我国南、北方一些地区比较属中等水平，其中栽培植物略高于野生植物。植物硫含量范围差别悬殊，最大值可为最小值的２６倍，以沿大城市的水系和地区的植物含硫量高。海河流域的土壤全硫含量平均值为０．０４３％（指耕地和天然植被的土壤），为正常土壤含量的中上水平，植物硫元素含量与土壤硫含量和有机质含量呈正相关趋势。
tudies the content feature of sulphur in various kinds of plants in Haihe River basin,and its relationship with the sulphur content in soil.It has been found that the content of to-tal sulphur in plants in Haihe River basin is 0.232 percent which is the lowest limit of thenormal content.This is a medium level compared to that in some areas in North or in South.The content of total sulphur in cultivated plants is slightly higher than in wild plants. The content of total sulphur in soil in the Haihe river basin is 0.043 percent on average.It is slightly higher than the average level of the normal soil content.The contents of sulphurin both plant and soil tend to have a positive correlation to soil organic matter.
