| Abstract: | With the aid of remote sensing and GIS technology,landscape patterns of various types of land use and their tempo-spatial distribution was studied through landscape pattern gradient analysis.Results show that during the years of 2002-2006,the overall landscape pattern of the city changed significantly,with urban land increased by 22.10%,while farm land decreased by 14.96%.Spatially,the present landscape features a gradient of urban area-rural-urban fringe-countryside,and temporally in time,the entire transe... |
