Abstract:A comparative study on annual production of macrozoobenthos community was carried out in a typical algal lake-Lake Houhu and a typical macrophytic lake-Lake Biandantang.The results showed that the annual production of macrozoobenthos community in Lake Biandantang (38.926 g/(m2·a)) was a bit lower than that of Lake Houhu(47.505 g/(m2·a)).The eutrophication of Lake Houhu, slightly higher than that of Lake Biandantang, which was much fitter for the growth of pollution-prone species of oligochaetes, resulted in more oligochaete production.Algal lakes bearing preferable situations for the existence of omnivorous gastropods like B.aeruginosa attained higher gastropod production.Large chironomids usually present weed-free, higher entrophication water body, which match the conditions of Lake Houhu, so Lake Houhu liad larger production of chironomid.Nevertheless, the proportions of macrozoobenthic production contributed by chironomids, oligochaetes and gastropods remained fairly stable, which were 14%-15%, 7%-8%, 77%-79%, respectively.
