RS and GIS Image Based Analysis of Urban Greenspace Landscape of Xuzhou City

The green space landscape pattern in the urban area of Xuzhou City was studied based on remote sensing image and supported by RS and GIS technology, and the gradient differences in the landscape pattern between the urban and suburban areas were analyzed by Gradient Analysis Method. The results showed that public greenspaces and other greenspaces were the main types of greenspaces in the urban area of Xuzhou City. The urban greenspaces were severely fragmented because of the impact of urbanization and human planning. The patch types of greenspace were usually simple in the shape, which was not beneficial to establishing and maintaining the biodiversity in the urban area. There were differences in the landscape indexes along the plot gradient, the landscape diversity and landscape fragmentation level in the suburban area were generally lower than those of in the urban area. The study on patch shape of the greenspaces showed that the patch shape in the urban center tended to be more regular than that of in the suburban fringe.
