不同施肥制度下水稻灌区面源污染排放的数值模拟
Simulation of Different Fertilizer Application Regimes Impact on Agricultural Non-point Source Pollution in Rice Irrigation District
摘要
Abstract
This paper takes Yangshudang small watershed in Zhanghe Irrigation System as the study area,using the improved SWAT distributed hydrological model to simulate the nitrogen and phosphorus pollution in this area. Daily runoff data from 2005 to 2009 and daily data of nitrogen and phosphorus pollution in 2009 in the study area were used to calibrate and validate correlative parameters. Then different fertilizer application regimes were simulated and analyzed in order to provide basis for making fertilizer management decisions in rice irrigation area which can increase fertilizer use efficiency and reduce pollution.关键词
