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 soil quality and grain yield in the black soil region of Northeast China. Based on the GIS platform and the soil erosion model, the digitalized plots for the management of erosion decision-making were established using remote sensing data, field sampling data and household survey data as data sources. The GIS-enabled digitalization of soil erosion warning and erosion control information decision- According to the degree of erosion in different plots, different decision-making suggestions on governance measures can be provided to realize the early warning of soil and water loss on the scale of plots and the digital management of water and soil conservation decision-making, and establish an information management model of soil and water erosion comprehensive control in black soil erosion area.
