Abstract:: In order to fully understand the relationship between ecological security pressure of cultivated lands and the development of its agricultural economy in Heilongjiang Province,we adopted the improved ecological footprint model to measure the ecological security levels of cultivated lands in Heilongjiang Province,to describe its spatiotemporal dynamic change characteristics from 2009 to 2018 and to summarize general rules. On the basis of that,decoupling model was also used to evaluate the decoupling relationship between ecological security pressure of cultivated lands and the development of its agricultural economy. The results show that:(1)from the perspective of time,ecological security degree of cultivated lands in Heilongjiang Province transitioned from ecological surplus to ecological balance and finally transformed to the critical overloaded status,so cultivated lands did not have sound ecological status;(2)from the perspective of space,the distribution of cultivated lands' ecological security in Heilongjiang Province was obviously unbalanced,which showed the spatial distribution of ecological deficit to ecological balance from the south to the north;(3)the decoupling state between ecological security pressure of cultivated lands and the development of agricultural economy was greatly influenced by agricultural production modes; in general,it gradually shifted from weak decoupling to strong decoupling and their coordination gradually increased; however,some areas also had unstable development. These research results can provide data and theory support for ecological protection of regional farmlands and the realization of the sustainable development of agricultural economy.
