Abstract:
In the report, 20 Rural settlement in Northern Hainan were used as the research samples, based on three landscape ecology patch shape index, the ratio of perimeter to inner area (SI1), the ratio of shape perimeter to the perimeter of a ellipse with equal aspect ratio, equal area with the shape (SI2), and the landscape fractal dimension (SI3), the figure-ground diagram method was used for the quantitative research. The results showed that fractal dimension (SI3) was used for the preliminary analysis of the boundary shape settlement, and then, combined with aspect ratio of the external rectangular (arc) and shape index (SI2), the further analysis were performed, which can be more comprehensive for the understanding of the complexity and fragmentation of the graphics, and which can be applied for the analysis of the morphological characteristics of rural settlements in northern Hainan.
