| Abstract: | According to different elevation,we set located monitoring sample plots in vegetation construction experiment and demonstration area of Three gorges reservoir fluctuation zone in Wushan section to observe the ecological adapation and the formation machanism of Cyperus rotundus on morphological tiaits,population density and biomass to flooding-drying habatate changes.The results showed that,plant heignt,leaf length of Cyperus rotundus in the shallow water area(altitude 155-170 m) was significantly higher tha... |
