【 摘 要 】

Lake Tempe was mostly covered by water hyacinth (Eichhorniacrassipes). Aufwuch community which live surround the aquatic plant has an important role in the food chain, as intermediate component between primary producerand higher secondary producer. This study was conducted in Lake Tempe, in order to analyse the association of aufwuch community towards aquatic plants and water quality. Sampling was carried out at five observation stations with three inundation zones. There were found 38 genera of from five classes, Cyanophyceae (5), Chlorophyceae (11), Bacillarophyceae (8), Euglenophyceae (2), and Chrysophyceae (1) as microphyto-aufwuch with density ranged from 16 544 840-203139505 ind/m3; 33 genera from four groups, Crustacea (10), Protozoa (8), Rotifer (14), Insect (1) of microzoo-aufwuch with density ranged from 138 969-351 834 ind/m3; and 15 genera from four groups, Gastropod (4), Insect (5), Crustacea (5), Larvae (1) as microzoo-aufwuch. The temperature of waters was ranged as 30,4-36 °C, depth 40-145 cm, Secchi depth 15.0-60.7 cm, pH 5.2-9.2, DO 2.9-16.9 mg/L, ammonium 0.005-0.013 mg/L, ammonia 0.0002-0.2912 mg/L, nitrate 0.5828-0.9113 mg/L, nitrite 0.004-0.0127 mg/L, and orthophosphate 0.0429-0.1325 mg/L.There were three groups of aufwuch in Lake Tempe, the microphyto-aufwuch, microzoo-aufwuch, and macrozoo-aufwuch, with appropriate water quality conditions for aufwuch life.
