Abstract: Based on combing relevant literature, the evaluation system of sustainable intensive use of cultivated land based on the “stress-state-response” (PSR) model was constructed, and taking Beijing-Tianjin-Hebei region as the research area, the sustainable intensive use of cultivated land use the status quo and changing characteristics were evaluated. The results showed that the sustainable intensification index of cultivated land in Beijing-Tianjin-Hebei regions increased from 2005 to 2015, but showed irregular fluctuations. The distribution of cold and hot spots in the sustainable intensive use of cultivated land showed a pattern of “hot in the central region and cold in the north and south”. The overall coordination of the system showed a stable trend from 2005 to 2015.The preliminary evaluation system of sustainable intensive use of cultivated land and its empirical evidence in Beijing-Tianjin-Hebei region can provide reference for the discussion of sustainable intensive use of cultivated land.
