[Objective] erstand the genetic diversity of Gleditsia sinensis.[Method] 215 G. sinensis samples were analyzed using AFLP (amplified fragment length polymorphism) approach.[Result] The results showed that total of 1 782 loci of G. sinensis genome were examined for molecular variation in which 1 389 loci were polymorphism, accounting for 77.94%. The average Shannon's and Nei's index were 0.256 and 0.168, respectively. At the species level, the total genetic diversity (Ht) was 0.127, suggesting a lower genetic diversity in G. sinensis populations. The gene flow and average genetic distance were 0.059 and 1.483, respectively. It is suggested that there were some genetic differentiations among the ten populations. The UPGMA cluster analysis showed that the G. sinensis populations were divided four types. The variance within population was the main part of the genetic variation of the species according to the AMOVA and Gst analysis.[Conclusion] In combination with on-site investigation, it is conclude that the pre
