Study on microstructure of ten plants with different living types and with certain zoology value, economy value and ex- tend apply value of the west alkaline district of Songnen plain with paraffin section method. Ecological adaptation to the west alka- line district of Songnen plain combine to it’s living environment was discussed. Certain gist be offered for selecting of plant species for ecologic reconstruct of the west alkaline district of Songnen plain. The results show that there are evident differences among dif- ferent plant’s leaves and the microstructure adapt to the surroundings. The leaf blades are all typical back-abdomen bifacial type. The upper dpidermis were formed by thick cells which line up densely. There are thick cuticle on the upper epidermis and the lower epi- dermis. Several pickle cells are in the upper epidermis between the two parallel nervation Leymus chinensis of Leymus chinensis, phragmites communis And Puccinella tenuiflora. The pickle cells are easy to lost water under drought condition which can resoult in the leaves to curl to the abdomen. The leaves of Polygonum divaricatum L. and Iris ensata Thunb are carnification. These are all reactions to the drought and alkaline conditions. 1

采用石蜡制片法通过对松嫩平原西部盐碱地区生活型不同且具有一定生态价值、经济价值和推广应用价值的10种优势植物的显微结构特征进行研究,并结合其生存的环境,探讨它们对松嫩平原西部盐碱地区的生态适应特性,为松嫩平原西部盐碱地区生态重建植物种类的选择提供一定的依据。结果表明:不同植物叶片之间具有明显的差异,并且植物叶片的形态解剖结构明显表现出与其生态环境相适应的特征。它们的叶片在结构上均表现出典型的旱生特点:上表皮细胞较厚且排列紧密,上下表皮都具有发达的角质层。羊草(Leymuschinensis)、芦苇(phragmitescommunis)和碱茅(Puccinellatenuiflora)在两条平行叶脉之间的上表皮内,分布着数列泡状细胞,干旱时极易失水而引起叶片向腹面卷曲;碱蓬(SnaedaglaucaBuuge)和马莲(IrisensataThunb)的叶出现了明显的肉质化,这都是对干旱盐碱环境的适应性反应。
