摘要
依据生态因子对蕨类植物的生态类型进行了划分.蕨类植物的生态类型可划分为5大类:光照生态类型、温度生态类型、水分生态类型、土壤生态类型和生境生态类型.光照生态类型包括阳性蕨类植物、阴性蕨类植物和耐荫蕨类植物3类.温度生态类型包括热带蕨类植物、亚热带蕨类植物、暖温带蕨类植物、温带蕨类植物和寒温带蕨类植物5类.水分生态类型包括旱生蕨类植物、中生蕨类植物、湿生蕨类植物和水生蕨类植物4类.土壤生态类型包括酸性土蕨类植物和钙质土蕨类植物2类.生境生态类型分为土生蕨类植物和附生蕨类植物两大类,附生蕨类植物又分为树上附生和石上附生2类.最终得出结论:蕨类植物生态类型的多样性与生态适应的多样性密切相关,蕨类植物的生态类型能指示生态环境的质量,也能反映植物区系间的地理亲缘关系.文中附有生态类型图片.
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.
