不同土地利用方式及开垦时间对岩溶山区土壤养分空间分布的影响
DOI: 10.3724/SP.J.1145.2011.00063, PP. 63-68
Keywords: 岩溶山区,土地利用,开垦时间,土壤养分
Abstract:
采集贵州普定典型岩溶山区7种土地利用方式和3个不同开垦时间（27a、39a、48a）的0~10cm、10~20cm、20~40cm土壤样品，进行室内理化分析.结果显示，林地土壤有机质、全氮、碱解氮累积量较多，玉米黄豆地含量最少.林地土壤0~10cm层有机质、全氮、碱解氮分别比玉米黄豆地高271.0%、317.7%、246.1%.林地和撂荒地对土壤养分循环较为有利.林地开垦为农业用地后，土壤有机质、全氮、碱解氮含量明显下降，全磷、有效磷、全钾含量没有明显变化，有效钾含量增多.开垦39a的0~10cm层土壤有机质、全氮、全磷、有效磷、有效钾含量高于开垦27a和48a土壤的含量，碱解氮低于开垦27a和48a土壤的含量；开垦27a的土壤全钾含量高于开垦39a和48a土壤的含量.开垦时间长或短对土壤养分含量的影响未表现特殊规律性，可能受到其他因素的影响.图2参20
