【摘要】：以陕北米脂沟壑区为研究案例,依据城镇空间形态结构的演变规律,结合陕北黄土高原丘陵沟壑区独特的沟壑空间体系,探讨该地区城乡空间动态发展的不同路径.在以人居空间高效分布与自然环境保护综合效益最大化为目标的分形理论指导下,通过比较不同城乡空间发展路径的总体差异及各自的阶段性特征,包括城乡规模、空间形态、分形维数等指标的变化趋势,总结米脂城乡总体用地形态扩展的适宜途径,引导人居环境朝着更为合理、优化的方向发展.研究结论有效地指导了米脂城镇化进程中的城乡协同建设与生态保护,提升了土地资源的综合效益,有助于改善粗放利用空间的传统模式.
[Abstract]:Based on the evolvement law of urban spatial structure and the unique gully space system of hilly region of Loess Plateau in northern Shaanxi Province, the different paths of urban and rural spatial dynamic development are discussed in this paper. Under the guidance of fractal theory which aims to maximize the comprehensive benefits of human settlements and the protection of natural environment, this paper compares the overall differences of different urban and rural spatial development paths and their stage characteristics, including the scale of urban and rural areas and spatial forms. The change trend of fractal dimension and other indexes are summarized, and the suitable ways to expand the overall land use form in Meizhi city and countryside are summarized to guide the development of human settlement environment towards a more reasonable and optimized direction. The conclusion of the study can effectively guide the urban-rural coordinated construction and ecological protection in the process of rice fat urbanization, promote the comprehensive benefit of land resources, and help to improve the traditional mode of extensive utilization of space.
