Land Use and Land Cover Change Based on Remote Sensing and GIS in Changping, Beijing, China and Lake Velence Watershed, Hungary

Because of the rapid economy development and the enormous society evolution, large scale changes of land use and land cover had occurred in areas of Beijing and Hungary in the past two decades. This paper focused on monitoring on LUCC(land use and land cover change) in Changping, Beijing, China and Lake Velence watershed area in Szekesfehervar, Hungary based on multi-temporal, multi-spatial and multi-source remotely sensed images and Geographic Information System( GIS). The study results showed that the characteristics and intensity index of LUCC were obviously different in two countries study areas. In changping, the types of land cover and land use had largely change from 1992 to 2006. The urban land increased sharply when the agricultural land decreased rapidly and waters areas mostly lost. It showed the typical urbanization characteristic. Whereas, the cultivated land increased and the forest lost mostly in Lake Velence watershed area from 1990 to 2004, and the urban land only increased slowly. The comparison study on contemporaneous land use and land cover change of two countries also illuminated that the land use and land cover change was mainly drived by the economy development and the nationmal land policy.
