Abstract:
By using the model of coordinated development degree and introducing multiple difference factor, the method of calculating the level of intensive utilization of cultivated land was improved. The internal coordination and intensive utilization degree of cultivated land in Henan Province were analyzed vertically and horizontally. The results show that the competition or cooperation relationship between the subsystem of cultivated land intensive use will lead to the reduction or enhancement of the intensive use levels of cultivated land. In the four subsystems of cultivated land intensive use, the subsystem of input intensity has been lower than the other three subsystems. Otherwise, it restricts the internal coordination degree of cultivated land intensive use and the overall level of intensive use of cultivated land. In the cross-sectional study of four years, there is no obvious spatial distribution of cultivated land intensive use in the 18 regions. During the research period, the intensive utilization of cultivated land in some areas has declined dramatically, which mainly are caused by the decline of subsystem score and the competition between the four subsystems. With the relative backwardness of agricultural income and the increase of rural migrant workers, local governments should actively introduce relevant policies to improve farmers' input intensity.
