凤城通远堡国有林场次生杂木林草本多样性的研究

Herb Diversity of Secondary Miscellaneous Forest in Tongyuanpu State-owned Forest Farm in Fengcheng City

利用凤城通远堡国有林场北山的标准地,依据6、7和8月3次不同时间的调查资料研究了次生杂木林内的草本植物生物多样性,通过对重要值、香农威纳多样性指数、优势度和均匀度等的分析,解释了该林分的草本植物的月变化规律。试验结果表明,不同月份植物多样性变化有明显的不同,不同月份生物多样性总体趋势呈从低到高方向变化。

Using sample plot in northern mountains of Tongyuanpu state-owned forest farm in Fengcheng City ,ac-cording to survey data at different time for three times in June ,July August ,the herb biodiversity of secondary miscellaneous forest was studied ;through important value ,Shannon Wiener diversity index ,dominance evenness , the monthly variation in the herbs of this stand was explained .Result shows that changes in plant diversity in dif-ferent months are significantly different ;the overall trend of biodiversity in different months shows a change direc-tion from low to high .
