The relationship between α diversity of plant community with different sampling scales and environmental factors were studied in this paper.

The niche breadth of main species in different synusia of a 76-year-old Chinese fir community in Ancaoxia,Fujian,China,were studied by different sampling scale based on the data collected from sample plots with an area of 2 400 m~2.

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.

We also tested whether the richness effects was the result of two types of mechanisms operating, "sampling effect" and "niche complementarity".

The physical models, especially, the continuum mechanics models, for size effects are discussed, together with related numerical methods.

However the know-how in traditional stamping process can not be directly used in Micro/Meso stamping field because of so-called size effects.

A concise review for the research advances of the macroscopic/ microscopic theories of linkage on size effects of solids is presented in the paper.
