| 摘 要： | 通过自然茶园土壤采样和室内实验分析，探讨浙江、江苏和安徽13个茶园土壤镍的污染状况、形态分布规律以及不同形态镍的含量与土壤镍总量和土壤理化性质的关系。结果表明：部分茶园土壤受到不同程度的镍污染；茶园土壤镍的形态分布有一定差异，按镍的含量多少排序,一般为残渣态＞交换态＞铁锰氧化物结合态＞有机结合态＞碳酸盐结合态；除了交换态以外的所有其他形态的镍含量均随土壤镍含量的增加而显著增加；碳酸盐结合态、铁锰氧化物结合态和残渣态镍含量随土壤pH的升高呈显著增加趋势，而交换态镍则呈减少趋势，但不显著；随土壤有机质含量的增加，铁锰氧化物结合态镍显著减少，而其他形态增加或减少的趋势均不显著；碳酸盐结合态、有机结合态和残渣态的镍含量均随阳离子交换量的增加显著增加；随粘粒含量的增加所有形态中的镍呈增加趋势，但除了残渣态外增加趋势均不显著。

| Abstract: | The pollution situation and fractionation of nickel in tea garden soils as well as the relationships between nickel fraction and total content of nickel and soil properties were studied by collecting the natural tea garden soils from 13 tea gardens located in main tea areas of China.The results showed that: some of the tea garden soils were polluted with nickel to some extent;the distribution of chemical fractions of nickel in the tea garden soils was residual>exchangeable>Fe-Mn oxides>organic>carbonate;the contents of the others except for exchangeable increased significantly with increases of the total contents of nickel in the soils;carbonate,Fe-Mn oxides and residual increased significantly with the rising of soil pH,however,the exchangeable decreased but not significantly;only Fe-Mn oxides decreased obviously with the organic content,the others increased or decreased but not significantly;carbonate,organic and residual were all increasing significantly with cation exchangeable capacity increased;all of the fractions increased with the clay content but only residual was significant. |
