摘要
土壤侵蚀严重地影响了东北黑土区的土壤质量和粮食产量。利用GIS平台结合土壤侵蚀模型,以遥感数据、田间采样数据和农户调查数据为数据源,建立了侵蚀决策方案管理数字化地块图,实现了GIS支持下的土壤侵蚀预警和侵蚀防治信息化决策,可以根据不同地块的侵蚀程度,提供不同的治理措施决策建议,实现了田块尺度水土流失预警及水土保持决策的数字化管理,建立了侵蚀黑土农区水土流失综合治理信息化管理样板。
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 com- prehensive control of soil and water loss in Northeast China.
