Abstract :
In this paper, using export coefficient model and RS and GIS techniques, the NPS pollution load of Drainage Basin of Dahuofang Reservoir in the year 2000 was estimated, and its spatial distribution was simulated. Results indicates that the total nitrogen load is 3.90X103 tons, and that of total phosphorus is 1.57X102 tons, in which cropland, Qingyuan County and Xinbin County are important contributories. Analysis on the intensity load of NPS pollution shows that Xinbin County is the highest NPS pollution load areas, and these areas should be paid more attention in the future.
