Aquatic macroinvertebrate community structure was studied in four maior streams of Masan City during the period of 1977-1979. Macroinvertebrates were collected at 18 stations over 4 major streams and quantitative data were examined by abundance, dominance indices, similality indices, diversity indices, etc. In whole streams, macroinvertebrates were composed of 37 species, 36 genera.. 30 families, 13 orders, 6 classes in 4 phyla, Among them chironomids and annelid: were most abundantly. Dominance indices showed most higly at Kyobang stream(0.98) and most lowly at Hoewon stream (0.81). Species diversity indices showed most highly at Hoewon stream (0.94) and most lowly at Kyobang stream (0.71). According to species diversity indices, all the streams studied was determined polysaprobic area.
