【科学60秒】985 城市规划公式 2013.7.15 Is There a Formula for Better Cities? 【科学60秒】985 城市规划公式 For the first time, more people now live in cities than the countryside—a trend of increasing urbanization that is expected to continue. 第一次出现,城市里的人口数量大于郊区的人口数量——传说中的城市化趋势正在加剧。 Based on data from thousands of cities on everything from number of patents generated to road lengths, researchers at the Santa Fe Institute have uncovered the math by which human settlements grow from town to city to metropolis. So, for example, a social network between people within the city grows in a mathematical relationship with the increase in the size and quality of infrastructure, such as roads, power lines and the like. 基于从数千城市中涵盖了如在公路长度方面产生的专利数量等各方面内容的数据显示,SantaFe研究所的研究人员们已经发现了人类定居迁移的数学模式。因此,比如,城市中人们的社交网络数目的增加情况与比如公路,电力线诸如此类的基础设施的质量与尺寸的数学关系。 In essence, the bigger the city, the greater the opportunities—but negatives or costs also rise, such as crime or traffic congestion. To optimize urban function, the research suggests following policies that allow for a denser web of human connections while minimizing the costs imposed by transportation and energy use. 其实,城市越大,机会越大——但负面因素或者花销也在增长,比如说犯罪或者交通堵塞问题。为了优化城市的功能,研究人员们建议下面的一些对策,比如说允许更密的人类关系网可以最小化因交通和能源使用带来的花费。 The real test of these ideas will be how they stack up against data from the burgeoning cities of the developing world. China alone has added hundreds of cities with millions of people in the last few decades—and wants to add yet more. To do it right, city planners will need to brush up on their math. 对这些想法的真实考量将会是他们如何从发展中国家迅速增长的城市中收集数据。仅中国在最近的几十年间就增加了数百座城市和数百万的人口——并且还在增加。为了更准确,城市规划者们将需要不断温习他们的数学知识。
