摘　　要：生态系统保护与经济的协调发展是城市发展的现实需要,也是高质量发展的必然要求。以成都城市群为例,从“压力-状态”的角度评估成都城市群生态重要性,并基于Tapio脱钩分析探讨生态重要性与经济增长的发展关系。研究结果表明:研究期间(2000年-2020年)成都城市群生态重要性水平偏低;各城市生态重要性水平差异明显,耕地占用和能源消耗是差异的主要因素;整体上看,生态状态水平与经济增长脱钩状态较好,但脱钩程度较低,主要原因是生态重要性增长水平低。在城市规划和发展中应该加强生态环境管理,减少耕地占用和化石能源消耗,减轻生态压力,提高生态重要性水平。The coordinated development of ecosystem protection and economy is a realistic requirement of urban development and an inevitable requirement of the high-quality development.Taking Chengdu urban agglomeration as an example,this research evaluated the ecological importance of Chengdu urban agglomeration from the perspective of the“Pressure-State”,and discussed the development relationship between ecological importance and economic growth based on the Tapio decoupling analysis.The results showed that:the ecological importance level of Chengdu urban agglomeration was low during the study period(2000-2020);There were significant differences in the level of ecological importance among cities,and the main factors were arable land occupation and energy consumption.On the whole,the decoupling state of the ecological state level and economic growth was good,but the degree of decoupling state was low,mainly because of the low growth rate of the ecological importance level.In urban planning and development,ecological environment management should be strengthened,farmland occupation and fossil energy consumption should be reduced,ecological pressure should be reduced,and the level of ecological importance should be increased.
