| 摘 要： | 对不同程度盐碱生境下羊草群落的生态分布及地上生物量作了研究，得出：影响羊草群落生态分布和生物量的主导因素是土壤含盐量和酸碱度（ｐＨ值），其中土壤含盐量是影响生物量的主要因素，并且以７月份最为显著，盐碱对羊草群落生物量影响还表现在不同盐碱生境下地上生物量季节动态存在差异。

| Abstract: | The study is on ecologica distribution and above-ground biomass of Leymu chinensis community in various salt-alkali habit.The conclusion is that the principal factor affecting ecological distribution and above-ground biomass is the salt content of soil and salt-alkali degree (pH). Salt content of soil is the important factor affecting biomass and the effect July is the most dominant. Subsurface biomass seasonal variation has differance in various salt-alkali habit. This is also the manifestation that salt-alkali affect leymus chinensis commnity biomass. |
