| 摘 要： | 分析测定了河北省农田主要类型耕层土壤中的Ni含量及土壤中Ni含量的剖面变化,结果表明,河北省农田土壤中Ni的平均含量为26.48mg/kg,含量范围为8.62～94.77mg/kg,土壤中Ni含量水平在20～30mg/kg范围内分布频率最高。土壤中Ni的含量总体变化趋势是由北向南、由西向东呈逐渐增加趋势。主要类型土壤中Ni的平均含量水平高低为棕壤土>潮土>褐土>栗钙土;4种类型土壤中Ni含量的剖面变化表现为下层略高于表层,但含量差异不显著。农田土壤中Ni含量的变化与土壤pH值、全盐量及有机质的含量变化相关性不显著。

| Abstract: | Ni contents in the soil tillage layers and in the soil profiles of four main soil types in Hebei province were determined.The results showed that the content of Ni ranged from 8.62 to 94.77 mg/kg,with a mean content of 26.48 mg/kg,and the highest frequency of Ni content ranged from 20 to 30 mg/kg.There was an increasing tendency of Ni content from north to south and from west to east.The order of mean Ni content of four main soil types was:Brown soil>Fluvo-aquic soil>Cinnamon soil>Chestnut soil.Ni contents of the subsoils were higher than those of the topsoils within the four soil types,but the differences were not significant.There was no significant correlation between Ni content and soil pH value,soil total salt content and soil organic matter content. |
