Estimating Agricultural Non-Point Source Pollution in the Upper Huairou Reservoir Using the Export Coefficient Model

Abstract:

Quantifying agricultural non-point pollution load accurately and understanding contribution of the pollution sources clearly is the base how to control non-point source pollution effectively. Pollution loads from agricultural non-point source in the upper Lianghuai basin of Huairou Reservoir, including Huaisha River and Huaijiu River basin, were estimated according to export coefficient modeling. The results show that total nitrogen and total phosphorus loads in Lianghuai basin respectively are 322.52 t and 35.769 t in 2011.The total nitrogen and total phosphorus load intensities in Huaisha River basin are higher than that in Huaijiu River basin. Farmland planting including orchard and cropland, livestock and poultry breeding and rural domestic waste make a greater contribution to total nitrogen and total phosphorus loads. The study can provide scientific basis for further understanding characteristics of the nitrogen and phosphorus loads and agricultural structure adjustment.
