An Analysis On The Changes And Their Driving Forces Of Cultivated Land Use In Hubei

The researches on regional land use change and its driving forces, especially for that of regional cultivated land use is the material basis for mankind's survival, its dynamic characteristics and the driving mechanism have become an important part of the research on Land use and Land cover change and has vital significance for mastering land use change rule and forecasting land use change tendency. Hubei Province is the one of seven provinces abundant in land resources and climate resources in China, its cultivated land changes are related to the sustainable development of not only the province but also the whole country. Thus, it is necessary to attach importance to the process and the driving forces of cultivated land change in this area for promoting the sustainable use of cultivated land in Hubei and guaranteeing the food security of Hubei and China.Taking cultivated land in Hubei as the research object and the county or city as the statistical unit, the dynamic process, the tendency forecast and the actuated mechanism of cultivated land use in Hubei are analyzed by applicating many kinds of mathematical method on the base of a series of statistical data.From the content, this article first summarized the present situations and the research significance for the land use change, the theoretical basis, the main technique and content of the regional LUCC.After introducing the regional nature, social economy condition and present situation of cultivated land use change on the base of historical statistical data of Hubei, the distributed characteristics and the change rules of farming resources' quantity and quality of Hubei are discussed from macroscopic to microscopic, from horizontal to vertical analysis, and the tendency forecast are also discussed.These analyses reveal the dynamic change characteristics of land use in Hubei.As land use changes are mainly affected by population, economy, science and technology, and other policy factors, the author established the equation that reveals the socio-economic driving forces of cultivated land use change by using the principal component and the regression analyses, and finally, carried on the synthetic quantitative analysis on driving factors by combining regional indicators of physical factors and then analyzed the space district of the driving forces in this foundation.
