Abstract: This paper examined the spatial variation of sediment yield in Northeast China, a large area with complex geology, climate, land use history, and extensive sediment monitoring. In order to develop regional sediment yield scale relations, and to then use them to interpolate the spatial pattern of sediment yield, the area was divided into ten sub-regions of first class and fifteen sub-areas of second class. And 200 stations were used to study the scale effects of sediment yield. Three regional trends were identified: (1) a decreasing trend, with sub-regions usually located on the upper reach of river basins, such as Nenjiang sub-region on the upper reach of the Songhuajiang River basin and Xiliaohe sub-region on the upper reach of the Liaohe River basin; (2) a flat trend, with sub-regions such as the Second Songhuajiang River basin and the lower reach of Songhuajiang river basin; (3) an increasing trend, with sub-regions usually locate on the lower reach of river basins, such as lower reach of the Liaohe River basin. Using these developed relations, areally-adjusted sediment yield maps were created over the entire Northeast China with universal Kriging interpolation.
