Abstract:

Black soil resources are the cornerstone of the comprehensive grain production capacity in northeast China. From the perspective of food security, on the basis of theoretical analysis, the ecological footprint model based on carbon footprint and yield factor correction was adopted, combined with the ecosystem service value, to quantify the ecological compensation standard of cultivated land and the urgency of some cities in black soil region in northeast China from 2011 to 2018. It is shown that the study area is the ecological surplus area of the cultivated land under food security, and 54.1% of the grain output carried by cultivated land is supplied to the ecological deficit areas in China. The compensation standards in 2018 should be Harbin 1.95 billion yuan, Suihua 2.36 billion yuan, Daqing 1.095 billion yuan, Changchun 1.305 billion yuan, Siping 2.595 billion yuan, Tieling 919 million yuan. By considering the economic development level of each city, Siping City and Suihua City have the highest priority in ecological compensation.

Key words: food security, ecological footprint, compensation standard, black soil region in northeast China
