网络结构空间格局相似度分析——以1938～2014年北京市骨干交通网络为例
发布时间：2018-11-22 12:10
【摘要】：某个区域在不同时间序列、不同尺度序列以及不同区域的格局之间通常存在一定程度的相似性,包括位置、形状、大小等空间特征,也包括非空间特征等。提出了一种"流水模型"空间格局相似性评价方法,引入了空间格局相似度系数和综合空间格局相似度系数。该方法兼顾整体与局部的格局特征,以某一时刻水流覆盖区域代替景观指数值对格局的描述,一定程度上降低了景观指数"一值多形"的不确定性,避免了空间相关性对统计学方法结果的干扰。以1938~2014年的北京市骨干交通网络结构数据为例,探讨了不同年度交通网络的相似程度,揭示了历年交通网络格局的变化趋势和格局的变化过程。
[Abstract]:There is a certain degree of similarity between different time series, different scale sequences and different regional patterns, including spatial features such as position, shape, size and non-spatial features. In this paper, a method for evaluating spatial pattern similarity of "flowing water model" is proposed, and spatial pattern similarity coefficient and synthetic spatial pattern similarity coefficient are introduced. This method takes into account the characteristics of the whole and local patterns, and replaces the landscape index values to describe the pattern by the water flow coverage area at a certain time, thus reducing the uncertainty of the landscape index "one value polymorphic" to a certain extent. The interference of spatial correlation to the results of statistical method is avoided. Taking the data of backbone traffic network in Beijing from 1938 to 2014 as an example, this paper discusses the similarity of traffic network in different years, and reveals the changing trend and process of traffic network pattern in the past years.
