| 520 | 3 | |a A quantitative understanding of riverine phosphorus (P) export in response to changes in anthropogenic P inputs (NAPI), land use and climate is critical for developing effective watershed P control measures. This study indicated that annual riverine TP export for the six catchments of the Yongan River watershed in eastern China increased 4.1-30.3-fold over the 1980-2010 period. Increased riverine TP export resulted from a 61-85% increase in NAPI and a 2.6-14.6-fold increase in riverine export fraction of NAPI due to 36-43, 30-125, and 65-76% increases in developed land area (D%), drained agricultural land area (DA%), and storm events, respectively. For the 31-year cumulative record, 1.6-14% of NAPI was exported by rivers, 40-64% was stored in the upper 20cm of agricultural soils, and 30-55% was retained in other landscape positions. An empirical model that incorporates annual NAPI, precipitation, D%, and DA% accounted for 94% of the variation in annual riverine TP fluxes across the six catchments and 31years. The model estimated that NAPI and legacy P contributed 42-92% and 8-58% of annual riverine TP flux, respectively. The model forecasts an 8-18% increase in riverine TP flux by 2030 due to a 4% increase in precipitation with no changes in NAPI and land use compared to the 2000-2010 baseline condition. Enhanced export of NAPI and legacy P by changes in land use and climate will delay the decrease in riverine P flux in response to NAPI reductions and should be considered in developing and assessing watershed P management strategies. | |
