Diagnostic Report on Key Issues of Black Soil Degradation and Agricultural Production

Taking Northeast China as a study area, this study uses multiple remote sensing datasets to systematically assess the vulnerability, resistance, and resilience of grain crop yields under the dual pressures of drought and declining soil quality from 2000 to 2016.The findings help reveal the resilience of grain crop yields under the interactive effects of land quality degradation and climate change, thereby providing scientific support for formulating adaptive ecological restoration strategies and enhancing regional ecosystem services.

Specifically, the main objectives of this study are: To identify the vulnerability of grain crop yields under drought and land quality degradation in Northeast China; To analyze the resistance and recovery of grain crop yields under different disturbances; To explore the impacts of different disturbances on the yields of various types of grain crops.
