Assessment of phosphorus loss risk from soil - a case study from Yuqiao reservoir local watershed in north China

Sammendrag

The Yuqiao reservoir located in Tianjin, north China, is the drinking water source for nearly six million people in Tianjin central city. Over the past decade, water quality of the reservoir has become poor due to increasing eutrophication trend. A case study of Yuqiao reservoir local watershed has been conducted in order to study the spatial distribution and level of risk of P loss. In this case, a simplified indicator tool was used for the assessment of P loss, which was classified into two groups: source and transportation schemes
