中文摘要： 分形理论是非线性科学三大前沿之一，对认知自然界及人类社会自相似现象有突出意义，其普适与哲学价值已得到广泛共识。黄土高原独特沟壑地貌的自相似性（分形特征）已得到相关研究充分论证，生成于该地貌的城镇空间布局也具有明显的自相似特征，数千年来形成了相对稳态与和谐的人地关系。随着陕北能源产业和城镇化急速发展，水土流失等生态问题不断加剧，陕北沟壑地貌这一地域关键性生态因子与城镇空间发展间的矛盾日益突出，对已有人地关系带来极大冲击。本研究借助分形理论，突破在单一分形体系内独立研究的方法，对陕北能源富集区具有分形特征的地貌与城镇空间进行耦合关联性研究，通过分形维数计算与比较分析，科学认知两者间自相似组织的内在规律，建立分形数理模型，并从整体与个体不同层次进行城镇空间形态适宜性模式研究，探索与地貌环境相适应的陕北城镇空间发展现实途径，拓展人居环境科学理论研究视野，并对其他生态敏感地区城镇空间研究提供借鉴。

英文摘要： Fractal theory is one of the three forefronts of Nonlinear Science, it has an outstanding significance about understanding the self-similarity of nature and human society. Its universal and philosophical values have reached a broad consensus. The self-similarity (fractal characteristics) of the unique gully landform of Loess Plateau has been demonstrated adequately. Urban spatial distribution rooted in the landform also has an obvious feature of self-similarity, to forms a relatively stable and harmonious relationship between man- environment over the past thousands of years. With the rapid development of energy industries and urbanization in northern Shaanxi, the soil erosion and other ecological problems are getting intensified. The contradiction between loess gully landforms, which is a regional and critical ecological factor, and urban spatial development become sharper. It brings a tremendous impact on existing relationship between man- environment. With the help of fractal theory, this research will break through the way of independent research on a single fractal system, and make a coupled correlation study between the topography,which in northern Shaanxi Energy-rich region with fractal characters, and the urban spatial form. In this project the fractal mathematical models will be set up and suitability
