中文摘要：

本文通过对中国知网数据库中的论文进行题名检索,从而获取对不同城市进行研究或关注的论文数量,并通过论文的数量对中国地级及其以上的城市规模分布进行研究.研究发现基于文献数量的中国城市规模分布基本符合捷夫法则.具体结论如下：其一,由于对上海和北京进行研究的文献数量相差较小,中国城市文献规模分布呈现出较低的首位度,而习惯意义上的“北上广”处在两个完全不同的等级体系.其二,Zipf 维数q整体水平小于1,表明学者对城市的研究较为分散.其三,Zipf 维数q 从2000 年到2012 年整体上呈现出不断下降的趋势,表明学者对城市的研究呈现逐步分散的过程.其四,中国地级及其以上城市文献规模的等级体系整体上呈现出从金字塔式向纺锥形结构演变,中等文献规模的城市在数量上占据多数.

英文摘要：

This paper gets the article amount on urban through searching thename of city in articles’title in CNKI database（www.cnki.net）. Whether or noturban hierarchical system based on amount of articles comfort’s to Zipf’s lawis studied. The basic conclusion is that China＇s urban literature hierarchysystem is in line with Zipf’s law. There are four conclusions in detail inthis paper. First, China’s urban hierarchical system presents a lower degreeof primate city because the gap of papers’number on Shanghai and Beijing isvery small. The three cities “Beijing Shanghai and Guangzhou”are in two completelydifferent hierarchies. Second, the q of Zipf is small and it suggeststhat the urban study dispersed over different size cities. Third, the q ofZipf from 2000 to 2012 as a whole presents the declining trend and it suggeststhat the dispersion degree of scholars’studies on urban is higher and higher.Fourth, the hierarchical of China＇s urban literature presents from pyramid tospinning cone structure evolution, and the number of medium-sized cities isincreasing.
