| 摘 要： | 自然保护已成为人类面临的重大问题之一，而自然保护的基本内容是保护生物多样性。羊草草原是松嫩平原上具有一定耐盐碱性的重要草场资源，由于过度放牧而导致让盐碱化加重，出现了植物种类组成各异的群落。盐碱化与植物多样性的关系如何，是本文研究的宗旨。本文从物种的丰富度、均匀性和多样性三个测度水平来探讨分析了物种分布格局随盐碱化梯度的变化趋势。

| Abstract: | Nature conservation has become a serious problem for human beings. And the core of nature conservation is to protect biodiversity. Leymus chinensis is an important grass resource in Songnen Pingyuan which is saline-alkali tolerant to some extent. Excessive grazing has aggravated salinization of leymus chinesis, and communities composed of different plants have emerged. The aim of this article is to investigate the relationship between salinization and plant diversity. The tendency of species distribution pattern that varies in relation to the degree of salinization is analyzed from three angles, namely, species richness, homogeneity and diversity |
