Abstract: Using the income reduction method and ecological factor equivalent method, taking Hukou County, Jiujiang City, Jiangxi Province, in the Middle and Lower Yangtze Valley Plain as an example, and comprehensively using the statistical data and land use data of Hukou County, the study calculated the spatiotemporal changes of the asset value of cultivated land resources in Hukou County in 2010 and 2020. The results showed that from 2010 to 2020, the economic value of cultivated land resources in Hukou County showed a decreasing trend, decreasing by 61.73%;the economic value of cultivated land resources in Shuangzhong Town, which was closer to the county seat, had decreased significantly, while the economic value of cultivated land resources in towns (farms) that were relatively far from the county seat had decreased less.From 2010 to 2020, the social value of cultivated land resources in Hukou County showed a significant upward trend, with a growth rate of 252.64%;among them, from 2010 to 2020, the social stability value of arable land resources in Hukou County showed a decreasing trend, while the social security value of arable land resources showed an increasing trend. The overall ecological value of cultivated land resources showed an increasing trend from 2010 to 2020, but the changes were relatively small. The soil conservation value from 2010 to 2020 was an important part of the ecological value of cultivated land resources in Hukou County, followed by waste treatment and the maintenance of biodiversity;except for Shuangzhong Town, Nanbei Port Aquatic Farm, and Maying Town, where the ecological value of cultivated land resources was decreasing, the ecological value of cultivated land resources in other towns (farms) was increasing. The asset value of cultivated land resources in 2010 was 5.418 billion yuan, reaching 11.998 billion yuan in 2020, with a growth rate of 121.45%. The significant increase in social value of cultivated land resources was the main reason for the increase in asset value of cultivated land resources.
