摘　　要：基于RS与GIS,结合遥感航片影像对徐州市绿地景观格局进行分析,用梯度分析法研究其城市中心与城市边缘的景观格局梯度差异。结果表明:徐州市区以公园绿地和其他绿地类型为主,由于受城市化进程以及人为规划的影响,城市绿地破碎化程度严重,绿地斑块类型的形状总体比较简单,不利于城市生物多样性的维护和建立;不同景观指数沿样带梯度表现出差异性,城市边缘区的景观多样性和破碎度总体低于城市中心,对城市边缘区与城市中心区的斑块形状研究说明,在一定范围内城市中心区斑块形状更趋于规则。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 reg- ular than that of in the suburban fringe.
