Abstract

Cultivated land intensive use is an important way of keeping agricultural sustainable development in rapid urbanization period. Traditional evaluative methods of cultivated land intensive use could not completely express the regional overall difference and partial spatial heterogeneity. This paper takes Hubei Province as study area, constructs the index system of cultivated land intensive use from three aspects of input intensity, use intensity and output efficiency, and uses K-means algorithm to zone the cultivated land intensive use level. The results show: (1) A good zoning result of cultivated land intensive use by using the characteristic of briefness and high-speed has been made. (2)There is a distinct spatial difference of cultivated land intensive use in Hubei Province. The result is zoned by western low-intensive zone, southern middle-intensive zone, eastern high-intensive zone and central fine-farming zone. The corresponding development strategy is also proposed according to the agricultural productive condition of each zone.
