本文研究了干草原向荒漠草原过渡地带7种禾本科牧草的生物学特性、生活型、根系类型、生态分布、生态特征及其叶片解剖结构。结果表明,其中有4种C_3植物,3种C_4植物,并各自有其旱生形态和结构特征。
In this paper, the biological characteristics, life forms, root system types, ecological distributions, ecological characteristics and leaf anatomical structures of seven grass species in the transitional steppe to desert steppe were studied. The results showed that there were 4 kinds of C 3 plants and 3 kinds of C 4 plants, and each had its own morphological and structural characteristics of xerophyte.
