摘　　要：开敞空间是古镇空间的重要组成部分,文章基于古镇边界形态量化分类结果,分别选取团状古镇、指状古镇、带状古镇为研究对象,运用计盒维数法,分析其开敞空间分维值和分形秩序。研究结果表明:古镇开敞空间分形秩序特征具备层级连续,面积递减;层级数量指数式迭代增长;古镇空间自相似性高,形状边界与自然环境紧密相关等特点。古镇总体分维值较高,是良好的分形体,则它们的分形秩序特征具备一定参考性,基于此,提出古镇开敞空间分形秩序优化建议。The open space feature is an important part of the spatial feature of ancient towns.Based on the quantitative classification of ancient towns'boundary morphology,this study selects the cluster ancient towns,finger ancient towns and belt ancient towns as the research objects,and uses the box-counting dimension method to analyze their open space fractal dimension value and fractal order,the results show that the fractal order of the open space of the ancient town has the characteristics of continuous hierarchy and decreasing area;the number of levels increases exponentially;ancient towns have high spatial self-similarity,shape boundaries are closely related to the natural environment and other characteristics.The overall fractal dimension value of ancient towns is high,and they are good fractal bodies,so their fractal order characteristics have certain reference value.Based on this,this paper puts forward suggestions for optimizing the fractal order of the open space of ancient towns.
