Abstract: The subject of the paper is to study the effect of the different river habitat on biological  diversity of microalgae in order to reveal the status of algae indicators in the evaluation of river  ecosystem health. The study is conducted to compare planktonic algae and epilithic algae in  Shendinghe rive (SR) and Qihe river (QR) of Danjiangkou reservoir in August 2010. The trophic  status is evaluated by saprobic system. There are 193 species (varieties) belonging to 98 genera and  7 phylums of planktonic algae and 61 species (varieties) belonging to 36 genera and 3 phylums of  epilithic algae in the samples of SR. There exist 165 species (varieties) belonging to 82 genera and  7 phylums of planktonic algae and 48 species (varieties) belonging to 10 genera and 4 phylums of  epilithic algae in the samples of QR. 15 genera instructions 21 species (varieties) of saprobic  indicators are identified in the monitored rivers. The number of oligonucleotide indicators in QR is  higher than that in SR, and the number of eutrophication indicators in QR is lower than that in SR.  The water quality of QR is Biologically superior to that of SR.
