| 摘 要： | 利用西藏色季拉山东西坡急尖长苞冷杉林15个样方的数据,对该林分物种多样性及土壤营养元素含量进行了分析,结果表明,两坡土壤pH值呈酸性,西坡不同海拔的土壤pH值变化大于东坡,土壤有机质、全氮、碱解氮等含量也大于东坡,东西坡有效钙含量均远远大于其它有效元素含量,但两坡有效钙平均值有较大的差异.对西坡多样性指数H′具有较大影响的因子是土壤有效铁的含量,而对东坡均匀度指数E具有较大影响的因子是土壤有机质的含量. |

| Abstract: | Research was conducted on the characteristic of the soil element and the relation with species diversity in the Abies georgei var.smithii forest on the eastern and western slope of Sejila Mountain in Tibet.The results indicate that the soil on the both slopes is acid.The change of the pH value of soil on the western slope is bigger than that on the eastern slope at difference altitude.The organic matter and total N,available N content in the soil on the western slope is higher than that on the eastern slope.The available Ca content of both slopes is higher than that of other available elements,but the average value of the available Ca of two slopes has a bigger difference.On the western slope the greater factor influencing the species diversity index is the content of available Fe.While on the eastern slope the factor influencing the evenness indices is the content of the organic matter. |
