摘要:
以抗震设防烈度9度的小城镇——云南省东川城区为研究对象,选取Zipf分形模型和差异度指数模型对城市避震空间的等级规模结构进行评价。研究证明了东川城区的避震空间的等级规模具有分形特征,并且呈现出由单分形到双分形的变化,说明了分形理论在小城镇城市避震防灾空间等级规模结构的评价中应用的可行性,也说明了城市避震防灾空间布局的复杂性和多元性。最后,根据东川城区防灾空间等级规模的特征,提出相应的发展建议。
Abstract:
The seismic fortification level 9 of a small town-Dongguan is studied as the research object, and Zipf fractal model and the Difference index performs is selected to evaluate the scale structure of urban disaster-prevention space. The study shows that the hierarchical structure urban disaster-prevention space in Dongchuan has the fractal characteristics, which assume from single fractal to double fractal, and indicate practicablity of the fractal theory applied on the hierarchical structure of small towns urban disaster-prevention space. It also illustrates the complexity and diversity of the distribution of urban disaster-prevention space suspension. Finally, the relevant development suggestions are put forward according to the feature of grading scale structure of space in Dongchuan.
