黑龙江省松嫩平原黑土耕地遥感辨识与空间分异特征研究
Study on Remote Sensing Identification and Macro-Spatial Differentiation of Black Soil Cultivated Land in Songnen Plain of Heilongjiang Province

采用遥感与地理信息技术，对黑龙江省松嫩平原黑土耕地分布进行了调查研究，全面阐释了黑土耕地在行政单元、高程分带、坡度分级、土壤类型等层面的空间分布特征，说明了耕地在上述指标不同阈值水平上的分布变化，取得了黑土耕地分布的现势性信息，为指导耕地保护与水土流失防治提供技术支撑。
Using remote sensing and geographic information technology, the black soil cultivated land dis-tribution in the Songnen Plain of Heilongjiang Province was investigated and researched, and the spatial distribution characteristics of black soil cultivated land at the administrative unit, elevation zone, slope classification, and soil type topics were fully explained, reflecting the changes in the distribution of the above indicators at different threshold levels have obtained the current in-formation on the distribution of cultivated land in black soil and provide technical support for guiding the protection of cultivated land and the prevention and control of soil and water loss.
