| 摘 要： | 从土壤养分含量、颗粒组成和腐殖质特征方面研究了呼伦贝尔沙地樟子松天然林土壤肥力变化特征。结果表明,随着沙地樟子松天然林年龄的增加,土壤有机质含量、全氮、全磷和速效磷含量表现出明显的增加趋势,而土壤速效氮含量反而降低,土壤pH值则具有降低的规律。土壤颗粒组成主要集中在20-200 nm之间,平均含量为63.04%-33.49%。沙地樟子松天然林在生长过程中,对土壤腐殖质组成及其含量具有显著影响,并且随着林龄增加,有利于形成良好的土壤腐殖质结构,提高土壤的保肥能力。 |
| 关 键 词： | 呼伦贝尔沙地 天然樟子松林 养分变化 腐殖质特征 |

| Abstract: | The characteristics of change of soil fertility in Pinus sylvestris var.mongolica natural forest in Hulunbeier sandy land has been studied at some aspects such as soil nutrients content,particle composition and humus feature.The results showed: with the increase of age of Pinus sylvestris var.mongolica natural forest,soil organic matter content,total nitrogen content,total phosphate content and available phosphate content have increased,but soil available nitrogen content has decreased,and the soil pH value... |
| Keywords: | Hulunbeier sandy land Pinus sylvestris var mongolica natural forest change of nutrients feature of humus |
