摘　　要：内蒙野丁香(Leptodermis ordosica H.C.Fu et E.W.Ma)的各器官内薄壁细胞均含草酸钙针晶,是对其生长地土壤高含钙量的有效适应;叶表皮细胞的胞质粘稠,则增加了其保水能力;此外,茎中发达的木栓层是良好的隔热材料,可以抵挡高温对它的伤害。结果表明内蒙野丁香具明显的旱化结构特征,是对荒漠区山地干旱环境条件的协同适应。鉴于此种的观赏园艺特性,可以尝试在内蒙古中西部地区的城市绿化中加以利用。The ceils of Leptodermis ordosica H.C. Fu et E. W. Ma all have calcium oxalate which is effectively adapted the soil＇s more calcium. Moreover, the leaf epidermis cells have ropy cytoplasm that can improve its ability of water keeping. Furthermore, thick phellem can oppose injure from high temperature. That all indicate that Leptoderrnis ordosica has the structures traits of xerophytes that is the coadaptation of thirsty environment. For its ornamental gardening characters, we can try to use it at middle and west parts in Inner Mongolia.
