摘要
通过对辽东山区18块样地的调查及数据处理,计算出各样地乔木、灌木、草本的Margalef丰富度指数、Gini均匀度指数和Simpson多样性指数。从调查及分析结果来看,在本研究区域内,海拔高度对调查区域内的物种多样性影响不大,郁闭度、坡向、坡度对物种多样性有一定影响。
The data collected from survey of 18 plots in the mountainous area of eastern Liaoning were processed for calculating various indexes, such as the Margalef richness index of trees, shrubs and herbs, Gini uniformity index and Simpson diversity index. The analysis result shows that altitude has a little effect on the species diversity, and the crown density, aspect, slope has certain influence in the study area.
