英文摘要Scientific understanding and measurement of cultivated ecosystem resilience is crucial for the protection of cultivated land represented by black soil and the sustainable development of cultivated land ecosystem. In this study, we took Qiqihar, a typical black soil region, as the study area and divided the cultivated land ecosystem into two subsystems, black soil ecology and human socioeconomic. And we constructed a "policy background generation process system composition" measurement element screening model (PGSM) to establish the subsystem index systems. Cultivated land ecosystem resilience in 2020 was measured by the Pressure-State-Response (PSR) model and the multiscale fusion model. The results showed that the resilience of the black soil ecological subsystem (54.27) in Qiqihar is higher than that of the socioeconomic subsystem (49.01), and their spatial distribution trends were opposite. The overall resilience of cultivated land ecosystem was moderately low (51.64) but spatially heterogeneous. Cultivated land resource endowment and human activities pressure had the greatest impact on the subsystem. Socioeconomic input was the primary problem in regional resilience. Based on these findings, we made suggestions for cultivated land protection in black soil regions. This study contributes to the scientific and comprehensive measurement of the cultivated land ecosystem resilience and provides reference for sustainable management of black soil systems in China and globally.
