摘要
The release of pollutants in Agricultural Runoff (AR) from a plastic canopy (PC) region in eastern Dianchi Catchment of China was investigated. The daily variation coefficients of water quantity in 2002 and 2003 were 15.9 and 7.6 respectively. From May 2002 to September 2003, local farmland had discharge of 2.9-3.21 m(2) d(1). Pollutant loads from research area to Dianchi Lake from October to April were 10.7 kgTN d(1), 2.91 kgNH(3)-N d(1) and 0.18 kgTP d(1). Dissolved Total Phosphorus (DTP) was the major form of TP. PCs changed the pollutant release mode of farmland, and farmland discharge mainly entered groundwater.
