Multi-functional Intensity and Coordination Degree of Cultivated Land in Hu'nan Province Based on Method of Entire Array Polygon Diagram
[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.
