| 摘 要： | Sediment samples at different depths were collected from a large shallow lake named Wuliangsuhai in China, in order to determine the response of sediment characteristics to trophic state change. The lake changed from natural state to eutrophication in the late 1970s, creating a Transitional Sediment Layer （TSL） that can be visually used to separate sediments derived from multi-biology and macrophytes. Sediment characteristics were enumerated as a means of corroborating extant eutrophication data from sediment record. Inferences about the timing and trajectory of eutrophication were made using sediment characteristics-based reconstruction. Water content, electrical conductivity, pH, organic matter, nutrient （total nitrogen and total phosphorus） and metals （As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn and V） were measured in about 20 different layers of 63-71 cm deep columns of the sediment.
