森林物种多样性保育价值评价方法改进——以将乐林场栲树次生林为例

Improvement of Evaluation Method of Forest Species Diversity Conservation Value——A Case Study of Jiangle County

在前人研究的基础上,增加龄组、起源2个影响因子,对基于Shannon-Wiener指数的森林物种多样性保育值评价方法进行改进,并以2012年将乐林场栲树次生林的调查数据为例,采用改进后评价方法进行保育价值测算,结果表明,增加龄组、起源评价因子更能科学的反映森林物种多样性保育价值。

The conservation value of forest species diversity is one of the hot issues in forestry science,and how to set a reasonable unit price is one of the important indicators to correctly assess the forest health.Based on the fact that the forest species diversity in different age-groups and origins varies,an improvement was made on the Shannon-Wiener index based evaluation method by adding two factors：age-group and origin.Applying the sublot survey data of castanopsis fargesii secondary forest in 2012 in Jiangle Forest Farm,a verification of the improved method was made.The results demonstrated that the improved method could more scientifically reflect the forest diversity conservation value.
