摘要基于生态演替的生态学原理和Lotka-Volterra模型,提出了四种城市生命周期模型:波动演替型、演替生长型、演替衰退型和快速生长型。以北京为例,运用1978-2014年的数据进行了实证研究。结果显示,北京城市生命演替总体呈上升趋势,且其演替周期为4-9年;北京城市生命最近的演替周期从2012年开始,且处在快速发展类型,需要进行技术、经济、规划、建设和政策等调控,以促进北京城市走向可持续发展。 Based on the ecological principle of ecological succession and Lotka- Voherra model, this essay constructsfour urban life -cycle models： succession fluctuation model, succession growth model, succession recession model and rapidgrowth model. The essay takes Beijing as a case study with its data collected from 1978 to 2014. It finds out that Beijing＇ s succession process reveals an upward trend and the succession cycle of Beijing is four to nine years. Beijing＇ s latest succession cycle starts from 2012 and it is still on a rising stage. In order to avoid the city turning towards a cyclical recession, adjustments and controls on technology, economy, planning, construction and policy are reauired.
