【摘要】：基于多时相TM影像和GIS空间技术,计算了徐州城市空间形态的分形维数和紧凑度指数,运用象限方位分析和缓冲区分析方法,对研究区城镇建设用地的空间分异特征进行定量分析。结果表明,1983~2013年,徐州城镇建设用地扩展了1.4倍;全市范围内,中心点西南区为建设用地扩展的核心区,而中心城区整体向东南方向移动;城镇扩展强度呈现中心向外围"圈层式"扩展趋势。
[Abstract]:Based on multitemporal TM image and GIS space technology, fractal dimension and compactness index of Xuzhou urban spatial form are calculated, and quadrant azimuth analysis and buffer analysis are used. The spatial differentiation characteristics of urban construction land in the study area are quantitatively analyzed. The results show that the construction land in Xuzhou has been expanded 1.4 times from 1983 to 2013, the central southwest is the core area of the construction land expansion, and the central urban area moves to the southeast as a whole. The intensity of urban expansion shows the trend of "circle layer" expansion from center to periphery.
