摘要：

The evaluation and early warning of the ecological security of cultivated land are crucial to food security and social stability in the post-epidemic era. In this study, we construct a cultivated ecological security assessment index system based on the pressure-state-response (PSR) model in the main grain-producing areas of China. The entropy method and the multi-factor comprehensive weighting method are used to evaluate the ecological security of the cultivated land in the study area from 2007 to 2018. We propose an integrated model that combi...
