Using RS and GIS technique to monitor China urbanization development

Rapidly urbanization can cause many serious social, environmental and ecological problems, so it is important to monitor urbanization in spatial distribution and dynamic change using RS and GIS technique. We use the 1:100000 resource and environmental dynamic vector database of China to acquire the 1KM grid urban land change data collection for decade from end of 80´s to 2000 which captures all of the high resolution urban land use information by calculating area percentage for urban land use category within every 1KM grid cell. Based on this data, we analyzed the spatial relationship between the urban development and population, social economy, and nature environment status. In the result, some developing features and trends of Chinese urbanization were brought forward.
