According to the investigation on the local situation of aquatic vegetation in Littoral Regions of Gonghu Lake and Meiliang Bay of the Wuxi Taihu Lake, the species of aquatic vegetation, community forms and biomass were acquired. Then a contrast of vegetation distribution characteristic between the two Littoral Regions was analyzed which induced to the analysis of impact factors. In the treatments designed as varying degree oxidation intimidate, the heavy metal cadmium and the ammonia nitrogen single and compound poisons, the COD sewage cultivate, the plant growth opsonin processes, the effect of the intimidate environment on the submerged plant growth and the physiological biochemistry characteristic was analyzed. The effective method to improve the resist adversity of submerged macrophyte was discussed. The results will give a suggestion to the restoration of the submerged macrophyte, the efficiency and reconstruction in Lake Ecosystem.
