Abstract:

To clarify the marginalization of farmland in Guangdong which is a developed area and its main influencing factors, using three major diagnostic indicators of “unit cost net income index”, “agricultural land use intensity index” and “agricultural crop planting area index”, we summarized the marginalization characteristics of farmland in Guangdong from 2000 to 2015, selected 19 factors affecting the marginalization characteristics of farmland, and explored the core influencing factors of farmland marginalization by geo-detector method. The results showed that: there were 3 obvious farmland marginalization in Guangdong from 2000 to 2015, appeared in 2001-2002, 2005-2006 and 2010-2013, respectively, and the third marginalization lasted for the longest time and was the most serious; the level of social and economic development and structural indicators and the indicators of changes in the structure of rural household resource elements had a great impact on the marginalization of farmland, among them, the proportion of tertiary industry value, the fixed assets investment of rural farmers, and the total planting area of grain had a strong explanatory power to the marginalization of farmland, q was 0.8067, 0.8055, 0.7916, respectively. Any interaction between the two factors can enhance the explanatory power of the marginalization of farmland.
