Abstract:

This paper was based on the study of the physiological and ecological characters of main species within family of Ulmaceae, and the analysis of the soil type and climatic conditions in Mt. Lanya. The suitability of tree species there were also studied. The results showed that Pteroceltis tatarinowii, Zelkova schneideriana, Ulmus chenmoui, U.gaussenii, etc. in family Ulmaceae were the best species for limestone mountains in the eastern of Anhui Prvovince, because their physiological characters and succession suitability are adaptable to the high calcium and lacking water habitat.

Key words: Limestone moutain, Ulmaceae, Physiological and ecological character
