Abstract

Urban and suburban soil phosphorus (P) pools have a great impact on environmental quality. A total of 126 surface soil samples were collected from urban and suburban areas of a typical developing city (Lishui, in the southwest Zhejiang Province). The different P extraction solutions were used to predict P loss potential from the soil. The area of P loss risk index was mapped using the geographic information system (GIS) based on the risk classification. The spatial distribution map obtained clearly showed that the region of high P loss risk was mainly distributed in the old and central urban region and northeast edge of the studied area. A phosphorus loss indicator combined with GIS would be helpful for the city government to best predict and manage P loss in the course of urban sprawl
