摘　　要：乔木层盖度是森林群落的主要数量特征之一。在Matlab6.5的计算环境下,为获得森林群落乔木层盖度的数值提供方便可靠的计算方法。结果表明,与传统的目测估计法相比,该文提供的方法可以在很大程度上避免由于研究者的主观因素造成的估计值差异。Tree layer coverage is one of the primary numerical characteristics of forest community. However, the coverage of the same forest community often varied more or less between different researchers because of subjective estimation. With Matlab 6.5,a new method was introduced to efficiently compute the tree layer coverage of forest community. Compared with traditional method of measuring by sight,this method can provide more stable result between different researchers,avoiding uncontrollable subjective factors.
