黑龙江省松嫩平原黑土耕地水土流失遥感监测与防治策略

Remote Sensing Monitoring and Control Strategy of Soil and Water Loss in Black Soil Cultivated Land in Songnen Plain of Heilongjiang Province

摘要: 依托全国2018年水土流失动态监测项目实践，采取遥感与GIS空间分析技术，通过对水土流失驱动因子地形、植被、土壤、气象等因子的矢量叠加，利用水土流失模型分析和人工判读修正方式开展松嫩平原黑土耕地水土流失强度、类型界定，查清黑土耕地水土流失类型、面积及分布特点，提出相应防治策略，为黑土地保护与生态农业建设提供科学依据。

Abstract: Based on the practice of the national soil and water loss dynamic monitoring project in 2018, re-mote sensing and GIS spatial analysis technology are adopted to develop the Songnen Plain through vector superposition of driving factors of soil and water loss, such as topography, vegetation, soil, meteorology, etc., using the analysis of soil and water loss model and manual interpretation and modification. In order to provide scientific basis for the protection of black land and the construction of ecological agriculture, we should define the intensity and type of soil and water loss, find out the types, areas and distribution points of soil and water loss, and put forward the corresponding prevention and control strategies.
