摘要
绿色空间与城市发展不断耦合作用,构成复杂的生态—社会系统,影响着城市的适应水平。近年来,在极端气候、公共卫生等不确定事件频发的背景下,如何评估系统适应水平成为研究热点,也就必须探索绿色空间与城市发展的耦合特征及影响因素。引入适应性循环理论,阐释绿色空间与城市发展的耦合过程,及其对城市适应能力的影响;建立绿色空间服务水平与城市发展水平的评价体系,构建耦合度模型。本文以成都市为实证对象进行定量测算,归纳出成都在1949—2018年的绿色空间与城市发展耦合变化特征及系统适应水平变化规律,分析耦合特征的形成机制,最后提出相应调控策略和建议。研究结论以期为我国其他城市科学评估系统的适应水平提供参考。
The continuous coupling between green space and urban development constitutes a complex ecological-social coupling system,which affects the adaptation level of the city.As an important natural space in the city,the service level of green space is constrained by urban development,and at the same time affects the level of urban development.On the spatial and temporal scales,it is the interactive coercion with the development of urban material space.The coupled system has the characteristics of a complex adaptive system.Individuals in the system can communicate with the environment and other individuals,continuously perform evolutionary learning,and change their own structure and behavior according to the learned experience.In recent years,extreme climates such as heavy rain,drought,public health and other uncertain events have frequently occurred,and the impact on the urban coupling system has become increasingly obvious.Therefore,how to evaluate the adaptation level of the system has become a research hotspot.Traditional researches mostly describe the static state of the system qualitatively,which ignores the dynamics and complexity of the system.This paper introduces adaptive cycle theory to explain the coupling process of green space and urban development,and its impact on the adaptability of urban coupling systems;compared with traditional systems theory,adaptive cycle theory does not pursue absolute final results,but more pay attention to the process of system evolution.The system state is no longer seen as static and unique,but as dynamic and transformable.In addition,it can link the coupling degree of the internal subsystems of the system with the adaptability of the system.Therefore,the adaptability level of the coupled system can be judged by analyzing the function relationship of the subsystems.In order to quantitatively measure the coupling degree between the green space service level and the urban development level,it established an evaluation system and corresponding indicators.The green space service
