摘要：Temporal changes in extracellular enzymes were studied by fluorometric assay of the pre- and post-dredging sediments of Taihu Lake. After dredging, most of the assayed enzymes were depressed significantly except for lipase and sulfatase. Sediment dredging had a profound impact on the hydrolytic activities, which was a reflection of the functional composition of the microbial community of the lake sediments. The activities of the assayed enzymes did not significantly correlate with abiotic factors such as pH, redox potential, or total phosphorus, but their activities were significantly correlated with total organic carbon and total nitrogen except for three carbohydrases.
