Abstract:

The change of the cultivated land use intensive degree is related to the food security and social and economic sustainable development. In this paper, by using the multivariate statistical analysis methods of stepwise regression and pathcoefficient analysis and so on, we carried out a study of the driving mechanism of the change of the cultivated land use intensive degree in Hubei Province from 1990 to 2008. The results showed that: the intensity degree change of cultivated land use increased steadily. The prices of agricultural products,cultivated land quality and the fiscal policy to support agriculture were the main factors to influence the cultivated land use intensive degree. The above three factors were not only the direct cause to influencing the cultivated land use intensive degree, but also the indirect cause of other factors, which also had an influence on the cultivated land use intensive degree. Under the market economy condition, the farmers' cultivated land use behaviors had showed a marketization trend. Consequently, we should enhance the agricultural prices  gradually, ensure the quality of land consolidation implementation, improve the quality of cultivated land, and intensify the policy efforts to support the agriculture, in order to improve the famers’ agriculture production enthusiasm and the cultivated land use intensive degrees, and promote the farmers’ income and ensure the national food security.〖HJ1〗〖HJ〗
