Results show that A. glauca and P. angelicoides had a higher （50%） frequency at Chipkoan, Garpak and Phagati forest, R. emodi had a higher （60%） frequency at Rishikund, Suki and Himtoli, and A. benthamii had a higher （70%） frequency at Suki and Khambdhar The densities of A. glauca （0.6 plants·m -2 ） and P. angelicoides （0.5 plants·m -2 ） were higher at Chipkoan and Garpak sites than at other micro-sites, while densities of R. emodi （0.8 plants·m -2 ） and A. benthamii （1.0 plants·m -2 ） were higher at Suki and Khambdhar sites. A. glauca had highest total basal covers （TBC） （1.2 cm 2 ·m -2 ） at Chipkoan, P. angelicoides had highest TBC （0.92 cm 2 ·m -2） at Lati kharak site, A. benthamii had the highest TBC （6.48 cm 2 ·m -2 ） atKhambdhar, and R. emodi had highest TBC （4.53 cm 2 ·m -2 ） at Rishikund. For the four studied species, A. glauca showed a contagious distribution, P. angelicoides and R. emodi showed the random and A. benthamii showed the regular type of distribution.展开更多
