    Abstract:

    [Objective] The multi-functional intensity and coordination of cultivated land in Hu’nan Province were analyzed to provide a reference for improving the multi-functional management level of cultivated land. [Methods] The multi-functional intensity and coordination of cultivated land in each county of Hu’nan Province in 2018 were calculated by using the entire-array-polygon diagram method and the systematic clustering method. [Results] ① The multi-functional comprehensive intensity of cultivated land in each county of Hu’nan Province weakened from the northwest to the central, and to the southeast areas, while the multi-functional coordination increased first, and then weakened from the west to the centre, and to the east of Hu’nan Province. ② Based on the individual functional intensity of each unit, the multi-functional development mode of cultivated land in each county of Hu’nan Province showed five types of development mode: multi-functional weak coordination mode, multi-function coordination mode, multi-functional strong coordination mode, ecological priority development mode, and social-led development mode. Spatially, from the west to the central and east areas of Hu’nan Province, cultivated land multi-functional development model changed from ecological priority development model to multi-functional weak coordination, multi-functional coordination transformation, and finally into cultivated land multi-functional weak coordinated development mode. [Conclusion] The results of the study are in line with the agricultural strategic pattern of “one circle, one district, two zones” implemented in Hu’nan Province, and can reflect the multi-functional spatial condition of cultivated land in Hu’nan Province objectively.
