【摘要】：某個(gè)區(qū)域在不同時(shí)間序列、不同尺度序列以及不同區(qū)域的格局之間通常存在一定程度的相似性,包括位置、形狀、大小等空間特征,也包括非空間特征等。提出了一種"流水模型"空間格局相似性評(píng)價(jià)方法,引入了空間格局相似度系數(shù)和綜合空間格局相似度系數(shù)。該方法兼顧整體與局部的格局特征,以某一時(shí)刻水流覆蓋區(qū)域代替景觀指數(shù)值對(duì)格局的描述,一定程度上降低了景觀指數(shù)"一值多形"的不確定性,避免了空間相關(guān)性對(duì)統(tǒng)計(jì)學(xué)方法結(jié)果的干擾。以1938~2014年的北京市骨干交通網(wǎng)絡(luò)結(jié)構(gòu)數(shù)據(jù)為例,探討了不同年度交通網(wǎng)絡(luò)的相似程度,揭示了歷年交通網(wǎng)絡(luò)格局的變化趨勢(shì)和格局的變化過(guò)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.
