摘　　要：分析北京西卓家营湿地12个水环境因子(含盐量、溶解氧浓度、pH值、浊度、总氮浓度、总磷浓度、化学需氧量、Cl-浓度、SO42-浓度、氧化还原电位、水深和水温)与沉水植物群落组的关系。运用双向分类矩阵,将13种沉水植物分为8个类群。通过对环境因子和沉水植物群落样方进行DCCA排序,得出第1排序轴主要反映Cl-浓度,而第2排序轴反映溶解氧浓度和水深。Relationships between submerged plants community and 12 hydro-environmental indicators such as salinity,dissolved oxygen concentration,pH value,turbidity,total nitrogen concentration,total phosphorus concentration,chemical oxygen demand,Cl-concentration,SO42-concentration,redox potential,water depth and water temperature in Xizhuojiaying wetland were analyzed.The 13 species of submerged plants were classified into 8 groups by using two way indicator species analysis(TWINSPAN).According to the comprehensive analysis on environmental factors and DCCA ranking axis,the first ordination axis mainly reflected Cl-concentration,while the second ordination axis reflected the dissolved oxygen concentration and water depth.
