It is of great significance to systematically analyze the cultivated land system resilience(CLSR)for the black soil protection and national food security.The CLSR is impacted by planting structure adjustment and cultivated land quality decline,posing major hid-den dangers to food security.It is urgent to evaluate the CLSR at multiple spatio-temporal scales.This study took Liaoning Province in the black soil region of Northeast China as an example.Based on the resilience theory,this study constructed the CLSR evaluation sys-tem from the input-feedback perspective at the provincial-scale and the city-scale,and used the rank-sum ratio comprehensive evalu-ation method(RSR)to analyze the key influencing factors of CLSR in Liaoning Province and its 14 cities from 2000 to 2019.The res-ults showed that:1)the time series changes of CLSR at the provincial-scale and the city-scale in Liaoning Province were similar,both showing an increasing trend.2)The CLSR in Liaoning Province presented a spatial pattern of'high in the west and low in the east'at the city-scale.3)There were seven and six main influencing factors of CLSR at the provincial-scale and the city-scale,respectively.In addition to the net income per capita of rural households,other influencing factors of CLSR were different at the provincial-scale and the city-scale.The feedback factors were dominant at the provincial-scale,and the input factors and feedback factors were dominant at the city-scale.The results could provide a reference for the utilization of black soil and draw on the experience of regional agricultural planning and adjustment.
