Based on the field survey and 4 series of remote sensing data of soil and water loss, the temporal and spatial change of soil and water loss in Zhejiang Province was analyzed. The results showed that: total area of soil and water loss decreased after 1987, but area of ≥ strong erosion grade increased and new man-made soil and water loss accelerated; 9 of the total 11 regions in Zhejiang showed the same changing tendency as the whole province. Soil and water loss distributed in 83 of the total 90 counties in Zhejiang. Due to the special natural, social and economic situations, soil and water loss scattered in the wide regions of hills and mountains in Zhejiang, although the absolute loss amount was low but the relative loss amount was enormous, so the potential fatalness is very high.
