| The ophemeropterans such as Epeorus pellucidus, Uracanthella rufa and Drunella uculea were dominated in station 1. It was generally showed the stable aquatic communities with low dominance index values throughout the year in station 2. The first dominant species in station 3 were all mayflies with the average DI value of 0.38. The first dominant species of Uracanthella rufa known as relatively tolerant species in station 4. A crustacean species Gammarus spp. have frequently occurred as the 1st or 2nd dominant species in station 5. Limnodrilus socialis, and Chironomus spp. were dominated in stations 6 and 7 Station 1, 2 and 3 were classified as oligosaprobic status according to their average diversity index values ranging from 3.46 to 3.52. Station 7 showed $alpha$-mesosaprobic water condition with the overall average diversity value of 1.26. In general, the equitability and species richness values in the same sampling areas had close relations with their diversity values. The dendrogram drawn by dissimilarity values among 7 sampling sites indicates that the macrobenthic communities were divided into 3 groups£º stations 1, 2, 3 and 4£» stations 6 and 7£» and station 5 alone. |
