摘要/Abstract

摘要： 分形理论是用于研究自然界中没有特征长度而又具有自相似性的图形和图像。它的发展为土壤等复杂体系的定量化研究提供了一种有效工具。以川西米亚罗地区几个不同强度人为干扰下的亚高山人工针叶林为对象,研究了其土壤颗粒和土壤微团聚体分形特征的变化,探讨了利用分形维数来表征人为干扰对亚高山人工针叶林土壤的影响,为研究亚高山针叶林生态系统恢复与重建提供了又一途径。

Abstract: Fractal theory which is used to study the natural figures and images with self-similarity but without characteristic length offers an effective tool to quantitatively investigate the complex systems such as soil.This paper studied the fractal features of soil particles and micro-aggregates under the subalpine coniferous forests with different intensity anthropogenic disturbance in Miyaluo area of West Sichuan,and approached the effects of the disturbance on the forest soils attributed to different fractal dimensions.The study introduced a new way to research the recovery and reestablishment of subalpine coniferous forests.

Key words: Manis pentadactyla, Burrow, Habitat selection, Dawuling Natural Reserve
