Abstract:

Revealing the characteristics of regional cultivated land management pattern helps to interpret the characteristics of cultivated land management model from the regional level, which will effectively propose the key points and development direction of regional cultivated land use transformation. This study initiated an evaluation model of cultivated land management coordination degree based on the three elements of “intensive-scale-capacity,” and used the coordination degree function and exploratory spatial data analysis method to reveal the evolution characteristics of the cultivated land management pattern in the county of Hunan Province. The results show that: (1) The coordination level of cultivated land management in Hunan Province was high overall from 1990 to 2014. The spatial pattern was significantly different. For example, the “Changzhutan” hilly area did show a higher intensive index. The Dongting Lake plain area exhibited a higher scale index. The main municipal district and its surrounding county capacity index was relatively high. (2) Due to different geographical locations and socio-economic impacts, there were significant differences in the temporal and spatial agglomeration characteristics of cultivated land management elements in Hunan Province. In the spatial dimension, the coordination degree of cultivated land management changed from “large agglomeration” to “small agglomeration.” In time dimension, the scale index autocorrelation was strong, the distribution was concentrated, and the productivity index was weakly correlated and distributed. (3) From the “input-scale-output” process, the plain area exhibited “high-high-high” signs, the hilly areas exhibited “high-low-low” characteristics, and the mountain areas were characterized by “low-low-low.” Combined with the characteristics of the spatial and temporal evolution of cultivated land management pattern, it is suggested that Hunan counties should adopt an intensive management model based on food crops, with economic crops as the main business model and characteristic crop management model.
