Research on the status of decoupling between ecological security pressure of cultivated land and agricultural economic level in Inner Mongolia
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.
