Plant species diversity of fragmented forests and their values for conservation and restoration

Abstract

Abstract: Forest fragmentation is the most important single factor leading to biodiversity loss.Besides fragment size,plant species diversity is also affected by edge e ffects,instantaneous sampling effects,relaxation effect,rescue effect by long -distance dispersal,and matrix etc.The paper reviewed the changes in species c omposition,abundance,characteristics of the fragmented forest.Many fragme nts deserve conserva tion,but proper evaluation and criteria are needed.Forest fragments also play ro les in determining the aims of ecological restoration and serving as seed source s for restoration.Several methods were proposed for the conservation a nd management of fragmented forest.

Key words: Chinese fir stand, Clear cutting land, Control burning land, Soil fertility
