中文摘要：

对江西6个毛竹主产县8个林地的土壤有效Cu、Zn、Fe和Mn含量分布进行研究,结果表明其含量差异变化均较大。0～10,10～30和30～50cm平均有效Cu含量分别为0.70,0.51和0.39mg/kg,排埠、双峰和官山林地有效Cu含量主要分布在0.5～1.0mg/kg,分别占全部样地的77.8%,100%和88.9%;除太平山庄外,10～30cm和30～50cm土层有效Cu含量均低于0.5mg/kg。有效Zn的平均含量分别为2.00,1.34,0.86mg/kg。有效Fe的平均含量分别为19.41,15.93和13.56mg/kg,三爪仑样地0～10cm土壤有效Fe含量在20～25mg/kg,占全部样地的88.9%;10～30cm在15～20mg/kg,占全部样地的55.6%。土壤有效Mn平均含量分别为16.37,12.13和9.20mg/kg,太平山庄样地0～10cm和10～30cm土壤有效Mn含量为15～20mg/kg,均占全部样地的66.7%。方差分析表明,不同样地土壤有效Cu、Zn、Fe和Mn含量均达极显著差异。相关性分析表明：土壤有机质和有效Fe含量之间呈显著正相关,与Cu呈负相关,与10～30cm和30～50cm土壤有效Zn和0～10cm有效Mn呈负相关但不显著。除0～10cm的土壤有效Fe和Zn含量之间不显著外,其它微量元素之间均达显著差异或极显著差异。

英文摘要：

The distribution characteristics of available Cu,Zn,Fe and Mn of soil samples from bamboo forests of 8 sites in 6 main producing bamboo counties in Jiangxi Province were studied.The results showed that the differences of these available microelements in different sites were obvious.The average contents of available Cu in the 0-10 cm,10-30 cm and 30-50 cm layers were 0.70,0.51 and 0.39 mg/kg respectively.The available Cu contents were 0.5-1.0 mg/kg in Paibu,Shuangfeng and Guanshan,accounting for 77.8%,100% and 88.9% respectively.The available Cu contents in the 10-30 cm and 30-50 cm layers except in Taiping Hills were less than 0.5 mg/kg.The average contents of available Zn in the 0-10 cm,10-30 cm and 30-50 cm layers were 2.00,1.34 and 0.86mg/kg respectively.The average contents of available Fe in the 0-10 cm,10-30 cm and 30-50 cm layers were 19.41,15.93 and 13.56 mg/kg respectively.The available Fe content in the 0-10 cm layer in San Zhualun was 20-25 mg/kg and accounted for 88.9% ,15-20 mg/kg in the 10-30 cm and accounted for 55.6% .The average contents of soil available Mn in the 0-10 cm,10-30 cm and 30-50 cm layers were 16.37,12.13 and 9.20 mg/kg respectively.The available Mn contents in the 0-10 cm and 10-30 cm layers in Taiping Hills were 15-20 mg/kg and both accounted for 66.7% .The available soil Cu,Zn,Fe and Mn contents were significantly different among all the forests at the three depths.The correlation analyses showed that there was a significant correlation between soil organic matter （SOM） and available Fe,and a negative correlation between SOM and available Cu.There were no significant differences between soil available Zn in the 10-30 cm and 30-50 cm layers and available Mn in the 0-10 cm,but the correlations were negative.The correlations were significant in different soil layers among these microelements except available Fe and Zn in the 0-10 cm layer.
