Research on temporal and spatial variation information of urban land: A case study of Taiyuan City

The temporal and spatial variation information of the land use illustrates a city's development tendency. In this paper, we obtained three land use maps by interpreting and classifying the remote sensing images of different periods in Taiyuan. Then, the area of different land use types was calculated by vector conversion module in ENVI software. Furthermore, we carried out the fusion of attribute information and obtained the corresponding land use conversion matrix by ArcGIS software. Finally, the analysis of land transfer speed and influence factors was conducted by applying the dynamic degree model of land type. The results can provide reliable references to make decisions for the local urban development.
