The indices of specific pollution sensitivity index(IPS)and standardized biological diatom index (IBD)are applied on Ruppia maritime with good living form to evaluate water ecological quality based on epiphytic diatom community.There are 36 diatom species belonging to 9 families and 13 genera with the dominant species of Cocconeis placentula var.euglypta,Cymbella tropica,Achnanthidium minutissimum, Nitzschia amphibian and Gomphonema minutum.The results show IPS and IBD vary from 10.3 to 13.6 and from 14 to 14.7,respectively,indicating the good water ecological quality of R.maritime.There are more than 70%, 60%,80%,70%,70%and 80%,respectively,of diatom ecotype of autotrophic and heterotrophic nitrogen uptake metabolism,high and moderate oxygen requirement,circumneutral and alkaliphilous pH,fresh brackish salinity, β-mesosaprobous and α-mesosaprobous saprobity,and eutrophic state.The results indicate the good water ecological quality of R.maritime is pH 7.0-8.0,Cl concentration 0.1-0.5 g·L-1,relatively low N contents,low organic pollutions,enough oxygen and moderate nutrient concentrations.IPS and IBD can comprehensively indicate the above environment requirements for R.maritime.
