【 摘 要 】

To reveal the characteristics of solid phase TSS (Total suspended substance) distribution and transported flux in urban river, and explore its effect on TN (Total nitrogen) and TP (Total phosphorus) transported fluxes. The TSS concentrations and flux, TN flux and TP flux, river runoff flux were be monitored and calculated systematically in Baoxiang River, the results shows that: (1) the annual TSS quantity transported by Baoxiang River into Dianchi Lake was 578.86t. Urban areas were the major transported areas of TSS, and summer and autumn were the main transported periods. (2) TSS has a certain correlation with TN (R2=0.28, P2=0.34, P
