Abstract:Soil erosion has seriously affected black soil quality and food production in Northeast China. Based on GIS and RUSLE, a digital land-block map for decision making and management of soil erosion is made and the early warning and information decision making for erosion control with support of GIS is accomplished, by using remote sensing images, field sampling and farmer survey as data sources. Through this system, different control measures and suggestions can be provided according to erosion degrees in different land types, and digital management can be implemented for early warning of soil and water loss and decision making of soil and water conservation at field scale. In this way, information management model is established for comprehensive control of soil and water loss in Northeast China.
