Abstract: The pteridophyte ecological types have been divided based on ecological factors which influence the growth and distribution of pteridophyte in this paper.Pteridophyte ecological types include five types:light ecological types,temperature ecological types,water ecological types,soil ecological types and habitat ecological types.The light ecological types include heliophytes,sciopytes and tolerophytes;the temperature ecological types include megatherm,submegatherm,warm-mesotherm,mesotherm,microtherm;the water ecological types include xerophytes,mesophytes,hyrophytes,hydrophytes;the soil ecological types include acidophytes and calciphytes;the habitat ecological types include terraphytes and epiphytes.Eventually we draw the following conclusions:The diversity of pteridophyte ecological types is closely related with those of ecological adaptability,it also can indicates the environment quality with those of the pteridophyte ecological types,also reflect the floristic affinis between pteridoflora. The pictures of ecological types are provided in this paper.
