By means of statistic analysis on the dynamic state of the enrichment and declination of 59 local
populations in 12 surviving species in Klugieae from China ,the population extinction rate is calculated using the
formula of R ( %/ 20 years) = (1 - Wi/ Wi - 1) ×100. During the period of 120 years from 1870 to 1990 ,the
population extinction rate of species in Klugieae sharply increased while their habitats became severely fragmented. The population extinction rates of species in different groups are correlated with their phylogeny. The
primitive groups have higher population extinction rate than the derivative groups. The endemic groups , especially the endemic genera are inclined to suffer higher extinction than the widely distributed genera.
