摘　　要：采用定性与定量相结合的研究方法对龙井市城市形态进行研究,基于GIS平台,利用2006,2011年2期龙井市土地利用现状图、城市规划图等资料,直观展现了龙井市城市空间形态变化及城市形态的类型,并采用分形维数和紧凑度指数分析了2006,2011年龙井市城市空间形态的特征。结果表明,龙井市城市空间分形维数由2006年的1.196增加到2011年的1.218,说明城市边界形状变得复杂,城区周界变得不规则。而城市紧凑度指数由0.283降低到0.260,说明城市形态变得离散。因此,为提高城市的紧凑度,应增加城市南部和北部已开发土地的利用效率,以及提高城市东北部与中部的联系程度。Use the method of combining qualitative research and quantitative research to study the Long- j ing City form, based on ArcGis platform, using the 2006,2011 two issue of Longjing land utilization map, city planning maps and other information, intuitive display of the Longjing spatial morphology and the types of city form, and analysis of the characteristics of the 2006,2011 Longjing space form by fractal di- mension and compactness index. The results showed that Longjing City urban spatial fractal dimension in- creased from 1. 196 in 2006 to 1. 218 in 2011, it is explain that the city boundary shape becomes complicat- ed, the city perimeter becomes irregular. And compactness index is reduced from 0. 283 to 0. 260, the city became the discrete form. Therefore,in order to improve the city＇s compactness, should increase the utilization efficiency of the southern and northern city land has been developed, and improve the degree of northeastern and central city.
