the size of urban population

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.

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。

With the growing urban population, the increasing size of cities, cities have become increasingly heavy traffic loads, cities can use the public space is increasingly small.

随着城市人口的不断增长，城市规模的不断扩大，城市的交通负荷变得越来越重，城市中可以利用的公共空间也越来越少。

Study of population size hierarchy is the groundwork of the city planning. It is important to the population forecast of cities and urban system planning.

城市规模分布研究是城市规划中的一项基础性研究工作，对准确预测城市人口规模以及合理确定城镇体系结构具有非常重要的意义。
