Stand variables affecting understorey plant species diversity in natural forests

Abstract

Abstract: This paper studied stand variables affecting understory plant species diversity of three typical forest types in over-cutting forest region,northeastern China.The results of stepwise regression showed that management related stand variables affecting understory plant species diversity include tree stems per hectare,canopy closure and tree species diversity.They all can be adjusted through management practice.Therefore,it is necessary to control stand density and enrich tree species diversity by cutting and tree species mixing for maintaining and increasing understory plant species diversity.

Key words: Ecosecurity, Scale, Urban area, Regional ecosecurity pattern, Construction
