摘要
松嫩平原黑土区是我省重要的粮食生产基地。采用遥感与地理信息技术,对2000年至2019年度黑龙江省松嫩平原黑土耕地消长与迁移变化特征进行了调查研究,对该时间跨度内耕地面积变化量、变化途径与变化水平进行了全面剖析,为指导黑土耕地保护与水土流失防治提供技术支撑。
The black soil area of the Songnen Plain is an important food production base in our province. Using remote sensing and geographic information technology, the characteristics of black soil cultivated land in Heilongjiang Province from 2000 to 2019 were investigated. The change volume of cul-tivated land area, change path and change level were comprehensively analyzed, which provided technical support for guiding the protection of black soil arable land and the prevention and control of soil erosion.
