艾比湖湿地植物群落特征与土壤环境关系研究

Analysis of Relationship between Plant Community Characteristic and Soil Environment in Wetland of Ebinur Lake

结合野外调查和室内实验的数据,对艾比湖湿地植物群落多样性指数与土壤环境的关系进行研究。结果表明:研究区的42种植物,分属16科36属,多数为典型荒漠植被,归属于16个植物群落类型。各群落的组成简单,多样性指数值都较低,且不存在较大差异。土壤中的有机质含量都很贫乏,土壤偏碱性,多为盐渍土。除物种丰富度与pH值呈显著相关外,多样性指数与土壤因子之间无相关性。

The field investigation and laboratory data were used to study the relationships between the diversity index of plant community and the soil environment in wetland of the Ebinur Lake. The results showed that the major 42 plant species in the Ebinur Lake belonged to 36 genera, 16 families, in which most were typical desert vegetation and were classified into 16 groups. The composition of various communities was simple, the diversity index of plant community was low and the difference among different plant communities was small. The soil was lack of organic matter and most soils were saline soil and showed meta - alkalescence. Except the species abundance showed obvious relationship with the pH- value, the diversity indices had no relation with the soil factors.
