The article compares changes in arable land use between two regions with different economic development levels: Jiangzhou County and Wujiang City. The researchers found that as Wujiang City experienced rapid economic growth, the area of arable land decreased significantly. In contrast, Jiangzhou County saw an increase in arable land area over the years. The quality of arable land in Wujiang initially improved but has been declining recently, while the quality of farmland in Jiangzhou remained relatively poor. The study predicts that Jiangzhou County will face increasing pressure on arable land due to economic development, highlighting the need for measures to protect farmland and ensure food security.
