Journal ArticleDOI
Runoff characteristics and nutrient loss mechanism from plain farmland under simulated rainfall conditions.
TL;DR: The results showed that the rainfall intensity, the antecedent soil moisture content, and the vegetation cover status were the main factors that affected the surface runoff in the NCP.
Journal ArticleDOI
Spatial and temporal variations in nitrogen and phosphorous nutrients in the Yangtze River Estuary.
TL;DR: Based on spatial interpolation data from 2003 to 2010, combined with almost 30 years of nitrogen and phosphorus pollutant data, this research analyzed the variations in total nitrogen (TN), nitrate nitrogen (NO(3)-N), total phosphorus (TP) and phosphate-P (PO(4)-P) in the Yangtze River Estuary.
Journal ArticleDOI

TL;DR: Results of this study revealed the TGD had affected nutrient loads in the basin, and it had played a role in nutrient reduction after its operation.
Journal ArticleDOI
Uncertainty analysis of total phosphorus spatial-temporal variations in the Yangtze River Estuary using different interpolation methods.
TL;DR: Based on the 4 period sample data of total phosphorus (TP) collected from the Yangtze River Estuary in 2010 and 2011, the uncertainty of spatial-temporal variation was analyzed with interpolation methods of inverse distance weighted (IDW), local polynomial interpolation (LPI), ordinary kriging (OK) and disjunctive kriged (DK).
Journal ArticleDOI
Trend of dissolved inorganic nitrogen at stations downstream from the Three-Gorges Dam of Yangtze River.
TL;DR: The TRAMO/SEATS program, combined with the Hodrick-Prescott (HP) filter, was used to detect trends and potential change points in time series of dissolved inorganic nitrogen (DIN) at three stations along the Yangtze River, revealing that DIN has been increasing at all the stations since the 1990s, although variations exist.
