摘要
对海南岛霸王岭林区沿海拔梯度自然分布的热带落叶季雨林、热带低地雨林、热带山地雨林、热带山地常绿林4种热带森林类型林地土壤的养分含量进行了比较分析。结果表明:海南霸王岭林区此4种热带森林类型林地土壤的有机质、氮、磷、钾含量差异显著;其土壤养分的有效性较差,土壤养分的总含量位于全国平均水平的中上等级,高于海南全岛土壤养分的平均水平,说明海南岛的原始热带林能较好地保持林地土壤肥力。
The soil nutrient contents of four natural forests namely tropical deciduous monsoon forest, tropical low-land rain forest, tropical montane rain forest and tropical mountain evergreen forest distributed at areas of different altitudes in Bawangling of Hainan island, were compared and analyzed. The results showed that there were signifi- cant differences among 4 types of studied forests on the contents of organic matter, nitrogen, phosphorus and potas-sium. The soils of 4 forests shared the common characteristics of low nutrient availability. The total contents of nu-trients were higher than the average soil nutrient level of China, also higher than the average soil nutrient level of Hainan island, which suggested the natural forests in Hainan island had the promising capability of soil nutrient maintaining.
