[ Objective] Characteristics of ancient tea plant resources in Wenshan prefecture were studied to provide reference for protection and utilization of these ancient tea plant resources. [ Method] In this paper, the ancient tea plant resources in Wenshan area were investigated by visiting, literature and field investigation. [ Result ] The ancient tea plant resources in Wenshan prefecture maintained rich genetic resources. According to the investigation and statistical analysis, 43 spots and 8 583 ancient tea plants were found, about 5 species and 2 varieties of Sect. Then were recorded in this area. The average tree height, base around, branch height and crown of ancient tea plant was 6.89 m, 1.35 m, 0.63 m and 29.25 m^2 , respectively and its average variation coefficient was 52.11%. Among these ancient tea plants, 64. 86 % were growing well, 26.00 % were growing generally, 6.57 % were growing badly, and 2.00 % and 0.57 % were growing dying and deadly. In general, the comprehensive utilization of the ancient tea plant resources was low, which restricted the protection and utilization of the ancient tea plant resources. [ Conclusion] The present situation of ancient tea plant resources were basically mastered, and the ancient tea plant resources archives was established, which would provide basis for the protection and utilization of ancient tea resources in Wenshan prefecture.
