ABSTRACT
In order to reveal the spatial distribution characteristics of agricultural production, social security, and ecological security functions of cultivated land at the county-level of the Zuoyoujiang area of Guangxi, this paper analyzes the multi-functional spatial status of cultivated land in the Zuoyoujiang area of Guangxi. By constructing a multi-functional evaluation system of cultivated land, this paper analyzes the relationship of multi-functional cultivated land in 32 counties of the Zuoyoujiang area of Guangxi and uses the grey correlation analysis method and R/S analysis method to reveal the influence of each index on the multifunctional system of cultivated land and the future trend of the multifunctional index of cultivated land. The results show that from 2005 to 2020, the overall function of the cultivated land in the Zuoyoujiang area of Guangxi has been enhanced; from 2005 to 2020, the average value of the multi-functional comprehensive index of the cultivated land in the Zuoyoujiang area of Guangxi is in a state of “high at the edge and low in the middle”; the impact of each indicator on the overall function of cultivated land in the Zuojiang River in Guangxi is mainly due to the transition from the population, cultivated land resource endowment and factor input in 2005 to the level of economic development and urbanization in 2020; by calculating the Hurst value with the R/S analysis method, it can be seen that most counties have persistent characteristics, and only a few regions have anti-persistence characteristics.
