【Abstract】 Wuxiaochuan watershed is a tributary of upper Jiulong river in Fujian province, and its aquaculture was selected as a example to estimate nitrogen and phosphorus pollution loads caused by large scale aquaculture. Nitrogen and phosphorus pollution loads of Wuxiaochuan watershed were estimated by three methods respectively, which are ZHU NEI JUN LANG method (Japan), chemical analysis method and material balance method. The results show that Pollution loads estimated by ZHU NEI JUN LANG method is the largest, and pollution loads estimated by material balance method is lager than that of chemical analysis method. Last, some suggests in using the three methods correctly were presented.更多还原
