| 摘 要： | 城市防灾空间是城市的重要组成子系统，本文以地震高发的峨山县城（包括双江镇和小街镇）为研究对象，对县城防灾空间布局的分形特征进行研究，研究选取量化指标-随机聚集维数进行测算，意在对峨山县城城市防灾空间的分形特征进行验证，并对防灾空间布局体系进行分析。研究表明：1.峨山县双江镇和小街镇城市防灾空间布局具有分形结构；2.双江镇和小街镇城市防灾空间呈现二元分异结构；3.双江镇城市防灾空间受地震断裂带影响呈现多中心分形结构；4.小街镇防灾空间布局呈现一元化单中心分形结构。

| Abstract: | Urban spatial arrangement for disaster prevention is one of city’s important subsystems. Samples including Shuangjiang town and xiaojie town for their high frequency of earthquake are chosen here to illustrate the outcome of the research. Fractal characteristics of the disaster prevention layout have been examined. And the research is finished with the estimation of random aggregation which works as a quantitive indicator. The study shows that： 1 Disaster prevention system in Shuangjiang town and xiaojie town has a structure with fractal characteristics, 2 Each one is a kind of binary differentiation respectively, 3 disaster prevention in Shuangjiang town becomes a multi-centered fractal structure because of the seismic faults there, 4 Disaster prevention system in xiaojie town appears a single-centered fractal modes. |
