| 滨海城市社区的空间形态及其海岸线表现出一定程度的复杂性，发展量化描述方法对于其可发展研究有重要的理论与应用价值。本研究基于分形理论，以滨海城市厦门的高浦社区为研究对象，利用计盒法对该滨海社区空间形态和边界进行复杂性分析和分形维计算，研究社区空间形态复杂性演变规律。结果表明：作为典型海湾渔村的高浦社区空间形态具有分数维，呈现分形结构特性。自1989年至今，该社区空间形态的分形维数呈现增长态势；社区边界的分形维数呈现下降态势。社区空间形态的分形维数与社区建筑占地面积、建筑总面积、建筑密度、容积率都表现出相关性。这表明滨海社区在快速城市化进程中，社区规模急剧扩张可能会导致空间形态和边界复杂性的显著变化。 |

| Abstract: |
| Urban spatial form shows a certain degrees of complexity, and developing its quantitative description method is both theoretically and practically important for urban community construction in the coastal areas. Based on the fractal theory, this paper analyzes the spatial form of a typical fishery village by the sea, Gaopu community in Xiamen, by boxcounting method and calculates the fractal dimension to study the complexity evolution of community spatial form. The results mdicate that the spatial form of the community has fractal dimension characterized by its fractal structures. Since 1989 the fractal dimension of community spatial form increases but fractal dimension of the community boundary decreases. The estimated fractal dimension of community spatial distribution has statistical correlations with the total community building area, total construction area, building density, and volume ratio. The results indicate that community expansion may have led to significant changes in community spatial form and the boundary complexity due to 30year rapid urbanization in coastal areas. |
