Abstract

The black soil of northeast China is one of the most fertile but short-cultivated soil types globally. Currently, black soil-related research has attracted immense interest in soil geography research. This paper compares the degradation characteristics of the black soil quality in northeast China, analyzes the formation mechanism, and proposes a strategy to restore the black soil quality, an important scientific reference for national food security. The black soils in northeast China mainly cover the Liaohe, Songnen, and Sanjiang Plains. The soils have high fertility, but the natural environment and human activities have degraded them after reclamation. The degraded soils have low organic matter, low nutrient contents, damaged soil structure and deteriorated physical properties. The degradation of black soil quality in northeast China can be divided into natural and human factors. The natural factors include climatic aspects, topographic, and soil conditions, while human factors include over-cultivation, predatory management, poor farming systems and planting structure, and urbanization. Strategies for preventing and controlling black soil quality degradation include improved agricultural development planning, changing traditional management methods, and strengthening the monitoring and research on black soil degradation.
