Abstract:: Export coefficient mode was used to analyze the spatio-temporal changes of the non-point source (NPS) phosphorous pollution based on GIS&RS. The result indicates that the TP load caused by land use increased from 100.98 t in 1986, to 123.57 t in 1995, to 144.36 t in 2010; as far as spatial distribution of the TP load is concerned, the high phosphorous load mainly distributes in the flat River Valley, because there are many farm lands distributed in that region. As for land-use type, different land uses have different contributions to the total non point source pollution load, the TP from farm-land increased year by year, the contribution rate, is 89.5% in 1986, 91.35% in 1995 and 92.02% in 2010, the load of the forest-land and the grass-land had a little change, but the contribution rate decreases gradually, the residential load increases by a large margin, however, the contribution rate is very little. In the term of the sub-basin, the higher the proportion of the farm-land is, the more the TP load increases, the high TP load of the sub-basin expands from the eastern and central region to the whole watershed.
