摘　　要：研究耕地生态安全压力与农业经济发展的关系对于实现农业经济增长和保护耕地生态安全具有重要意义。文中利用Tapio脱钩模型对耕地生态安全压力和农业经济水平的脱钩关系进行测算,结果表明:1)就2010、2015、2020年截面数据来看,全区各盟市耕地生态安全值变化不大,生态安全等级相对较为稳定。2)耕地生态安全压力与农业经济主要呈现出3种脱钩关系:弱脱钩(占50%)、强脱钩(占30%)、强负脱钩(占20%),各盟市的脱钩状态整体向好,符合可持续发展目标。3)全区脱钩系数在2010-2020年期间呈较为明显的空间负相关,但并未出现明显的空间集聚效应。基于脱钩状态,将12个盟市进行分类,为后续有针对性地提出解决措施提供依据,进而促进研究区耕地生态保护和农业经济的协调发展。It is of great significance to study the relationship between the ecological security level and pressure of cultivated land and agricultural economic development for realizing agricultural economic growth and guaranteeing the cultivated land ecological security.Tapio decoupling model was used to measure and study the decoupling relationship between cultivated land ecological security pressure and agricultural economic level,and the spatial correlation analysis of the decoupling state was carried out with Moreland index.Research results are as follows:1) According to the cross-section data of 2010,2015 and 2020,the cultivated land ecological security value of the leagues and cities in the whole region has changed little,and the ecological security level is relatively stable.2) There are three decoupling relationships between cultivated land ecological security pressure and agricultural economy:weak decoupling(accounting for 50%),strong decoupling(accounting for 30%),and strong negative decoupling(accounting for 20%).The decoupling status of all leagues and cities is generally good,which is in line with sustainable development goals.3)The decoupling coefficient of the whole region shows a relatively obvious spatial negative correlation during 2010-2020,and no obvious spatial agglomeration effect appeared.Based on the decoupling status,the 12 leagues and cities are classified to provide as policy basis for subsequent countermeasures,thereby promoting the ecological protection of cultivated land and the sustainable development of agricultural economy in the study area.
