Other Abstract

 In order to clarify characteristic of riparian zone in Three Gorges Reservoir Region, we chose five typical tributaries and two sections in Yangtze River, 42 deposited sediment samples were collected from the riparian zone and control zone for analyzing grain diameter distribution, nutrient elements of TOC, TN, TP and K and the sediment source of Yangtze River and its tributaries in Three Gorges Reservoir Region. The results indicated that particle size distribution of sediments in Yangtze River riparian zone was coarser than tributaries’, silt clay in main stream showed obvious enrichment state, enrichment rate was up to 1.57.Both upper Yangtze River and its tributaries, 137cs activity in the upper elevation (170 m) was higher than the low elevation (160 m), deposition process and the sediment source were discrepancy due to the difference of water residence time. Nutrient elements of deposited sediments in Yangtze River riparian zone showed no obvious enrichment, on the other contrary, the nutrient elements showed obvious enrichment of deposited sediments in tributaries riparian zone, especially TP, enrichment ratio was up to 2.43.
