In this research, the author has developed a historical database on land use/cover change of change at various administrative units and introduced a simple model simulating year variations of fractions of five land use/cove categories;forest, agricultural land, grassland, urban and non-agricultural land, and others. This model is named GKSIM (Generalized Kane's Simulation Model) is introduced. First, we describe the background of fine development of GKSIM. GKSIM has been developed to be applicable to developing countries where land use/cover data and related socio-economic data are very much limited in spatial and temporal resolutions. Secondly, we will induce GKSIM mathematically and will show the concept of influential matrices, and will discuss the advantages of GKSIM. GKSIM succeeds to the advantages of both regression models and system dynamics models. Finally, we will show an example of GKSIM application to China, in which the projection of year variations of five la!! nd use fractions in China up to 2050 is carried out.
