摘　　要：以徐州市区为研究区,在遥感数据、土地利用数据和实地调查资料等多源数据的基础上,构建了基于土地利用方式的城市化水平评价指标较体系,利用格网GIS空间分析技术对徐州市区的城市化水平空间分异进行了定量分析。结果表明:徐州市区的城市化水平呈现空间差异较大,高度城市化区过于集中的特点,其次城市化水平整体存在明显的圈层结构,并在部分轴线上呈现轻微的波动特点。Taking the downtown of xuzhou as research area. Based on the Multl-source data that concluded remote sensing data, the data of land use and the field survey data,. Seting up a system of evaluation about urbanization level, which based on methods of land use. Using the grid GIS spatial analysis technology to quantitative analyze the level space differentiation of Xuzhou＇s urbanization. We can see from the results： the urbanization level of xuzhou city have taken on the characteristics that large space differentiation and highly urbanization area is too centralized. Secondly, urbanization level exists obvious eireling structures and some parts of the axis line took on slight fluctuation.
