Characteristics and Unit Load of Pollutants at a Paddy Field Area with Large-Scaled Plots
- 발행 : 2001.10.12
초록
Mass balance and unit load of pollutants were investigated at paddy field area during irrigation periods in 1999 and 2000. The amounts of irrigation water during irrigation periods were 3,690mm in 1999 and 3,160mm in 2000. The concentration of surface outflow is not so high as that of irrigation because 44% of irrigation water discharge without entering the paddy plots. The unit loads of pollutants during irrigation periods were estimated 19.2kg/ha for T-N, 0.29kg/ha for T-P and 47.5kg/ha for COD.
