Other Abstract



 In order to analysis spatial variation characteristic of grain diameter, nutrient elements s and heavy metal pollution with deposition sediment in tributaries bay of Three Gorges reservoir, we selected 9 typical tributaries bay, 54 deposition sediment samples were collected from the riparian zone for analyzing grain diameter distribution, capacity, organic matter, nutrient elements of TN, TP and K, heavy metal elements of Cr, Cu, Ni, Pb, and Zn. The results indicated that particle size distribution from Wujiang River in Fuling to the Modao stream in Yunyang present a trend of fluctuation, at different altitude in sand and clay content presented a moderate variation, silt has small variation.The index of geoaccumulation indicated that sediment in the riparian zone of three Gorges Reservoir tributaries bay, only Zn element in Zhenxi river, Longdong river and Long river, Pb element in the Modao Stream belonged to no-moderate pollution levels, and other elements in the tributaries were all no pollution level.
