Abstract:

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.

Key words: submerged plants, water environment, two way indicator species analysis(TWINSPAN), detrended canonical correspondence analysis(DCCA), Beijing wetland
