A method, trophic state-comprehensive index based on researches on the ponds ecosystem health had been proposed to assess the ecosystem health of 3 kinds of ponds under different water purification methods, the conventional water self-purification, using of immobilized bio-film structure of artificial substrates, and the using of floating bed vegetation (the Ipomoea aquatica). Firstly, 4 indices including Chla, SD, TP and TN were chosen to calculate the trophic status index (TSI). Secondly, nondimensionalizated indicators such as phy
