Abstract:
Land use transition is a new integrated approach of land-use and land-cover change (LUCC) study. Land use transition is also one of the major research contents of Global Land Project (GLP), a joint research agenda of the International Geosphere-Biosphere Programme (IGBP) and the International Human Dimensions Programme on Global Environmental Change (IHDP) to improve the understanding of land system dynamics. This paper develops a research frame for cultivated-land transition and land consolidation and reclamation in China, after reviewing the research on land use transition, the theories and models of land-change science, cultivated-land change and land consolidation and reclamation. The frame may include: (1) analyzing the spatial pattern of cultivated-land change in China; (2) understanding the influential factors of cultivated-land transition trajectory; (3) putting forward the theoretical hypothesis on cultivated-land transition; (4) modeling the spatio-temporal changes of cultivated land in China and defining the regional types of cultivated-land transition and the phases where they are in; and (5) providing theoretical and scientific basis for land consolidation and reclamation, an important way to conserve cultivated land in China.
