英文摘要	A high calcium level is an important ecological factor in karst regions. Studying the adaptation mechanism of karst plants to high-calcium environments can provide a theoretical support for revealing biodiversity maintenance mechanisms and for the comprehensive management of rocky desertification. Based on a field investigation, 59 common epilithic moss species were selected for the determination of the calcium content of the plants and soils. By chemical measurement and biostatistical analysing the calcium contents in the soil and epilithic mosses. It was found that the average calcium content of the epilithic mosses was 19.03 mg/g and the average calcium content of the soil was 14.41 +/- 8.41 g/kg. The effect of soil calcium content on plant calcium content is not significant, indicating that soil is not the main source of calcium in mosses. There were significant differences in the calcium contents of different families and genus. The average calcium content of Pottiaceae was highest in different regions and habitats than that of other families, and the average calcium content of Brachytheciaceae was loweret. Based on the relationship between the calcium content in epilithic mosses and soil to classify the adaptation methods of the epilithic mosses to the high-calcium environment in karst. The strategies of epilithic mosses adapting to high-calcium environment can be categorised into 3 types: 1) Random, in which the calcium content in plants varies widely with the change in the soil calcium content, which does not significantly affect the growth of the plant; 2) High-calcium, in which the calcium content in the plant remains high at different soil calcium levels; and 3) Low-calcium, in which the calcium content in the plant remains low at different soil calcium levels.
