摘要:
分别用Boltzmann统计热力学熵、Shannon信息熵、联合熵分析了秦岭南坡火地塘林区几个样地的熵值。结果表明，在无过度人为干扰情况下，熵值随海拔升高而递减。熵值不仅可作为物种多样性、丰富度的评价指标，而且可以说明系统的稳定性及演替方向。
Abstract:
The development and evolution of the concept of entropy were reviewed.The entropies of biodiversity of several sampling plots in Huoditang Forest Farm were calculated by using Boltzmann entropy,Shannon entropy and joint entropy.The results showed that without over disturbance of human beings, entropies of biodiversity decreased along with the increase of altitude.Within the same community moreover,the entropy of herbage layer was the highest,then shrub and tree layer,indicating that the entropies of biodiversity not only decreased along with the increase of altitude,but also decreased in the order of herbage,shrub and tree layer within the same community.It was concluded from the results that entropy can be used not only the index for the assessment of biodiversity and biorichness,but also for the assessment of biostability and evolution direction.
