ABSTRACT- In this paper, we propose a new system for understanding the biodiversity in different conservation areas. It includes three aspects: the capacity, the connectivity and the quality. The capacity refers to the numbers of biodiversity, including absolute and relative richness of the vegetation types N_v and D_v=(N_v-1)/lnA, species numbers S and d_Gl=(S-1)/lnA, and germ plasm resources within a nature reserve, and also the potential biological living space offered by nature resource. It means the total biological resources in a nature reserve. The connectivity refers to the flux of biodiversity, including similarity and connected status of the vegetation types SI_Li=2z/(x+y) and species numbers SI_C=2z/(x+y) among different nature reserves. The quality refers to the stability of biodiversity, including Relative species richness index RS_Li=d/d_max , Relative vegetation richness index RV_Li=D_v/D_maxv, Fastness to invasion species f_Li=1- S_i /S_t, weighted values, representativeness and vulnerability of special vegetations, special species, CITES species and rare species as the protected targets.

Key words: Biodiversity, Capacity, Connectivity, Quality
