摘      要：The population dynamic tendency of Adenophora Iobophvlla Hong as an endangered species and Adenophora potaninii Korsh as widespread species. has been predicted by the Leslie matrix. And the comparison and analysis on the age structures between two species have been carried out in this paper. The results demonstrate the A. lobophylla popuations which have the reasonable age struetures perform slowly negative or positive increment at altitude 2300-3400 m. Especially. below altitude 2700 m. there are many populations performing seriously declining tendcncy. Contrary, A potaninii populations could adapt to environment perfectly at the corresponding condition without finding the population which performs the seriously declining tendency. The differences in developing tendency of population between the two species demonstrate that A. Iobopliylla populations have the weaker ability to adapt to the external unfavorable conditions.
