从城市规模分布的位序-规模法则出发，推导出城市等级体系的二倍数法则。

This paper demonstrates the equivalent relation between the 2n rule of hierarchy of cities and the rank-size rule of city size distribution.

从前人的成果，即以人口表示的城市位序-规模法则和以建成区面积表示的位序-规模法则出发，演绎出城市的用地规模和人口数量呈异速增长。

We start at the rank-size rule by urban population and the rank-size rule by urban built-up area, and derive a mathematical relationship that the land use size of a city and its population.
