扎龙湿地芦苇叶片结构与生境关系的研究

The Relationship between microstructure of reed's leaves and Ecological environment of Zhalong Wetland

本文分别对扎龙湿地不同生境芦苇叶片的上、下表皮及横切面结构进行了细致的观察、比较和分析。结果表明:不同生境中的芦苇表现出不同的适应其生境的特征,主要表现在表皮细胞大小、气孔大小、数量、气孔在叶表面的覆盖面积以及表皮毛的有无上。芦苇在进化过程中为适应不同的生境形成了不同的叶片显微结构。

In this paper,upper and lower epidermis of reeds from different ecological environment of Zhalong Wetland was observed,comparatived and analysed respectively.The results showed:there are various characteristics which mainly displayed in the size of epidermis cell,stomata,the density and coverage area of stomata on epidermis in different reed leaves.In process of evolution,different microstructure of reed's leaves were formed to meet different ecological environment.
