Abstract: By referring the research results of various evaluation models, a priority exploitation ranking system was established for sustainable use of the wild ornamental plants in Mt. Shergyla. It consists of 8 coefficients, which are ornamental coefficient, endemic species coefficient, ecotope coefficient, volume coefficient, variance coefficient, endangered coefficient, resistance coefficient, and gained coefficient. By assigning different weights for them, the value of preferential exploitation (Ve) was calculated. Then, with K-means Cluster Analysis in SPSS (Statistical Package for the Social Science), the priority exploitation ranking of the 184 species of wild ornamental plants (belonging to 107 genera and 47 families) was done. And it will guide protection and utilization wild ornamental plants in Mt. Shergyla.
