摘    要:植物物种丰富度随山地海拔梯度的变化格局是生物多样性研究的热点之一.基于种-面积关系的任何模型对群落物种数目所作估计,其精度都依赖于样本的代表性、抽样尺度以及所涉及的分类群.作者以秦岭南坡森林群落样方实测的乔木种数据为例,借鉴群落最小面积(minimum area,MA)的概念及其确定方式,利用稀疏法(rarefacti...

关 键 词:稀疏法  最小表现样方数  物种丰富度  物种密度  秦岭南坡

Abstract:Species richness variation along altitudinal gradients has been among the hot topics in ecology.Models that estimate richness based on species-area relationships are dependent on representativeness,sampling scale and the classification of samples.In this paper,we have derived a new method to estimate minimum plot number(MPN),which is the minimum number of plots required to accurately estimate the species richness of a concerned region.Our approach combines the rarefaction approach that has been widely used ...
Keywords:rarefaction approach  minimum plot number  species richness  species density  the southern slope of Qinling Mountain Range
