城市生态系统多元协同理论与评估机制:以降碳减污扩绿增长协同度为例
Muti-dimension synergistic theory and assessment of urban ecological system:Case of synergy among carbon reduction,pollution reduction,greening and economic growth
摘要
Abstract
The future development of cities needed to focus on the interactions and response changes of multiple elements of the urban system,among which,synergistic effect,as a key point of the virtuous cycle of urban metabolism,guarantees the stability and risk-resistance of the urban system.This study aimed to construct a multi-element synergy analysis framework for cities from the perspective of synergy theory,exploring the synergistic relationship and internal law between carbon reduction,pollution reduction,ecological greening and economic growth of Chinese cities in the two major systems of natural environment and economic and social systems.This study established synergy models to evaluate the synergistic relationship in terms of quantity and efficiency.From 2000 to 2020,the quantity synergy between ecological greening and pollution reduction in Chinese cities continued to rise,and the quantity synergy between carbon reduction and pollution reduction,and between carbon reduction and economic growth remained stable.Chinese cities showed complex performance in efficiency synergy,among them,efficiency synergy between carbon reduction and economic growth in some cities have moved toward a weak synergy level since 2016.By the end of the time series,18.95％of China's cities reached strong level of multi-element quantity synergy,and 26.42％change into multi-element efficiency synergy.There was a non-linear relationship between urban ecological elements and multi-element comprehensive synergy,and the comprehensive synergy threshold increased with the urbanization rate.The level of multi-element synergy in Chinese cities was from weak to strong level in quantity,and from non-synergy to synergy in efficiency in the past 20 years.But most cities still needed to improve the level of multi-element synergy.Finally,this study put forward the development path of urban multi-element synergy to provide theoretical reference for urban synergistic governance.关键词
