摘 要：正According to the statistical data of Pteridophyte, this paper discussed the species, families and genera source and the distribution of Pteridophyte in east Kunlun Mts. of the Qinghai-Xizang （Tibet） Plateau. The ecological condition of Pteridophyte in this region has also been preliminarily studied. The author thought that the flora of Pteridophyte in east Kunlun Mts. and the adjacent area is young with poor species, simple ecological forms, and small scope of distribution. It converged wide temperate and anti-cold terrestrial species which came from the surrounding floras. This flora is a border distributive district of Pteridophyte in China. Among the ecological factors, low temperature is the key factor restricting the growth, development and the formation of the ecological characteristics and the distributive patterns of Pteridophyte in the region.
