| 摘 要： | 在野外调查取样和室内实验分析的基础上，对人工林与天然林的土壤养分进行比较分析，结果表明人工林土壤表层的有机质、全氮、全磷、全钾含量都明显低于天然林，反映了人工林对养分的旺盛需求和消耗，并且人工林还会造成土壤阳离子交换量的降低和土壤容重的增大。提出变炼山全垦为块状整地、轮栽并适当休闲养地、提高人工林生物多样性、建立复杂的人工林群落等措施，以实现桉树人工林土壤养分平衡与生态系统的良性循环。

| Abstract: | By field work and laboratory experiments,the differences of some soil properties between eucalypt plantation and natural forest were examined.The results showed that contents of soil organic matter,total nitrogen,total phosphorus and total potassium in surface soils of plantations were significantly lower than those of natural forests,indicated that large part of soil nutrients had been consumed by the plants in plantation.In addition,soil bulk density increased and the soil cation exchange capacity reduced... |
