The plant community characters of endangered plant Calophaca sinica habitats were studied using TWINSPAN classification. The habitats were all dominated by C. sinica and fell into 14 associations. The C. sinica community were affected by both natural and anthropogenic factors. Adequate sunlight and less human interference contributed to higher species abundance and evenness in the communities. Meanwhile, the regression analysis showed significant correlations between 6 out of 9 pairs of soil factors. Zinc content was correlated to 8 species diversity indexes, while the potassium and phosphate contents were correlated to 6 diversityindexes.
