| 摘 要： | 根据海南省五指山1954年和2003年不同时间土壤样品的分析结果,对半个世纪以来海南省五指山土壤的交换性H 、交换性Al3 和全N等化学性质变化进行了研究。结果表明,五指山土壤的交换性H 和交换性Al3 在半个世纪以来有明显的升高趋势,而全N和有机质有明显的下降趋势。通过进一步的方差分析发现,半个世纪以来全N和有机质的差异已达到极显著水平,而交换性H 和交换性Al3 则差异不显著。

| Abstract: | Such changes of chemical properties as exchangeable hydrogen?exchangeable aluminum and total nitrogen of soil of Wuzhi Mountain of Hainan Province in the last half century were researched according to analyzed results of the soil samples of different time in 1954 and 2003 in this paper. The results indicated that exchangeable hydrogen and exchangeable aluminum of the soil of Wuzhi Mountain increased obviously in the last half century, and the total nitrogen and organic matters decreased obviously. According to furthered analysis of variance, the difference between the total nitrogen and organic matters had already appeared extremely remarkable level in the last half century, but the difference of exchangeable hydrogen and exchangeable aluminum have not appeared remarkable level. |
