| 摘 要： | 目的]研究西藏色季拉山冷杉林土壤养分的空间变异。方法]在冷杉林1hm2样地内用网格法分3层取土样（共18个）,同时在标准木4个方向（共12个）、根区和非根区（共24个）取样,并测定养分含量。结果]冷杉林中土壤有机质含量为A层〉B层〉C层,全效和速效N、P、K含量总和均以B层最高,3层中均以全效K和速效K含量最高;标准木四周西边（下坡）有机质含量最高,全效N、P、K总含量南边最高,且根区总含量高于非根区。结论]色季拉山冷杉林土壤养分含量存在较大差异,林中表层土壤养分含量和标准林木个体附近养分含量均较高,为该区域森林土壤资源的科学管理、植被更新与重建提供参考依据。

| Abstract: | Objective] The research aimed to study the spatial variability of the soil nutrient of Abies georgei forest in Sejila Mountain in Tibet.Method] 18 soil samples were taken by grid method acquiring from 3 layers of the 1hm2 Abies georgei forest plot.The 12 soil samples were taken from four directions around the standard tree,and 24 soil samples were taken from the root zone and non-root zone.The nutrient contents in all soil samples were determined.Result] The rank of the organic matter content was A layer... |
