In order to study the differences in al.ae species and their biomass in water bodies in a region, three reservoirs and two l.kes at the center of Guanzhong Pl.in were chosen to identify al.ae functional.groups, measure biomass, and assess water qual.ty, from January2013 to December 2014. The water bodies represented different trophic l.vel.： one ol.gotrophic, three mesotrophic, and one eutrophic. Based on the Reynol.s’ functional.groups, they had 10 groups in common—B, P, D, X1, M, MP, F, S1, J, and G, but the al.ae biomasses and proportions were different. In the ol.gotrophic reservoir, functional.group B reached a peak biomass of 576 × 104 l.1, which accounted for 31.27%. In the eutrophic l.ke,functional.group D reached a peak biomass of 3227 × 104 l.1, which accounted for onl.13.38%. When sampl.s col.ected from other water bodies with simil.r trophic l.vel. were compared, we found differences in the al.ae species functional.groups. The potential.reasons for the differences in al.ae functional.group characteristics in the different water bodies in the region were water temperature and nutritional.states.
