| Abstract: | As one of the important research fields in the land use or in the LUCC,the expansion of the urban land use is one of the significant indexes to evaluate the urbanization level of a city.Based on the related multi-temporal and multi-source spatial data,this paper conducts a research on the expansion modes and spatial-temporal variations of the urban land use in Mianyang City,one of the science cities in Southwest China.It analyzes the expansion speed coefficient,the expansion intensity index,the compactness,... |
