Researches on Temporal and Spatial Changes of Suspended Sediment Nutrients and Source Contributions in Xitiaoxi River, China

Abstract:

Xitiaoxi River is the main discharge river of Taihu Lake. It is important to research changes of suspended sediment nutrients and their provenances for the water environment management. This paper analyzes temporal and spatial variations of nutrients in suspended sediments (SS) and establishes the geochemical model to quantify the proportions of SS sources with geochemical parameters in different reaches. The results show that the contents of SS and its nutrients of the downstream are significantly higher than the upstream and midstream. The contents of nutrients in SS in dry season are higher than in wet season. The C/N and IP/OP ratios of SS can effectively reflect the material source types in the different reaches, which are associated with land use types. Woodland is relatively higher contribution to SS in the upstream, arable lands become a major contributor to SS in the midstream, while urban land is the highest contribution to SS in the downstream. Seasonal changes also affect the contributions of land use to SS. Woodland and urban land show more contributions to SS in wet season than in dry season, whereas arable land and bank sediment show the higher proportions for SS source.
