Nitrogen Load from Rural Non-Point Source Pollution in Suburb Area of Shenyang: A Case Study of Damintun Town

Abstract:

The export coefficient method was used to calculate the nitrogen pollution load of Damintun town from 2005 to 2007. As the results show Damintun town's 3 years mean non-point source pollution nitrogen load was 749.6 t•a-1 including crop farming 505.4 t•a-1, livestock-raising 176.5 t•a-1 and inhabitants living 67.7 t•a-1 which account for 67.4%, 23.5% and 9.0% of the total nitrogen load respectively. A field survey was carried out to test the result got from the export coefficient method. Same as the conclusion got from export coefficient model, the nitrate nitrogen concentration distribution map drawn by the field survey data indicated that planting was the main nitrogen load source of Damintun town. To reduce the nitrogen load in Damintun town area rational fertilization is the principal way.
