神头二电厂灰场植物群落分析研究

Study of the plant community round discharging coal-dust field in Shentou second power plant

火电厂贮灰场常位于电厂附近平原地带 ,占地面积大 ,贮留时间长。以山西省神头二电厂马邑贮灰场为例 ,采用等级聚合分类分析、群落多样性与环境因子的方差分析和相关分析等方法 ,系统研究了灰场环境对植物群落类型、分布、多样性的影响。结果表明 :灰场区植物分为 4个群落 ,以强耐盐碱的碱蓬群落为优势群落 ,群落分布和多样性受灰场的影响较小 ,但随着土壤盐渍化程度的加重 ,植物群落多样性。

The discharging coal dust field of a firepower plant often lies in plain district,whose area is large and remain period is long.Cluster Analysis,ANOVA and Correlation Analysis were used to research the influence of Mayi discharging coal dust field to the community type,distribution,and diversity in Shentou second power plant in Shanxi Province.The results show that the herbaceous vegetation is divided into four communities and salt resistance halophyte (Form. Suaeda glauca ) is prevailing in the area.The pollution of discharging coal dust field to the distribution and the diversity of herbaceous plant community is light.However,community diversity and evenness will decrease with the increase of the salt content in soil.
