| 摘 要： | 通过对比分析金佛山4种植被下表土炭屑形态和大小,揭示出森林群落与草本群落表土炭屑存在着较明显的差异.从炭屑形态上来区分:亚高山草甸表土中炭屑较薄,大部分为长方形或长条形,且其纵向边缘平直,横向断口一端相对平直,另一端较参差;森林群落下表土炭屑都较厚,多为近圆形或矩形,边缘参差不齐.炭屑大小上主要表现为:森林群落表土炭屑较小,平均L/W值为1.56±0.05,且L/W值大于3的炭屑不超过10%;亚高山草甸群落表土炭屑L/W值为1.77±0.10,且仍有超过10%的炭屑L/W值大于3.

| Abstract: | A comparative analysis of the morphology and size of the charcoal fragments in the surface soil under four vegetations in the Jinfo Mountains reveal considerable differences between forest communities and herb communities.In morphology,charcoal fragments in the surface soil of subalpine meadow are relatively thin and most are rectangular or like a long bar in shape.Their vertical margins are even and straight while part of the horizontal fracture is even and straight and the other end is uneven and irregula... |
