Sustainable development is a hot topic of global concern and sustainable human settlements (HS) are crucial to people's happiness. Thus, strengthening the construction of HS will help enrich human settlements geography with theories of HS interactions, clarify the existing problems of the Chengdu-Chongqing urban agglomeration (CC), promote the harmonization of the human-land relationship, and realize the SDGs. The results were as follows. (1) the quality of HS exhibited an upward trend with diminishing disparities in PLE functions. (2) A spatial layout featuring the high quality of HS in the east and west and low quality in the central areas was identified, with Chengdu and Chongqing serving as two high-value core areas. (3) The evolution of the quality of HS levels to achieve a leapfrog shift was challenging and the spatial spillover effect and phenomenon of "club convergence" were evident. (4) Living function was a primary obstacle at the criterion layer and indicators within production function became major obstacle factors at the element layer. These findings have enriched the research scope of human settlements geography from the scale of urban agglomerations, and provided scientific decisions for the SDGs.
可持续发展是全球关注的热点话题，可持续人类住区对人们的幸福至关重要。因此，加强人类住区建设将有助于用人类住区相互作用理论丰富人类住区地理学，厘清成渝城市群（CC）存在的问题，促进人地关系协调，实现可持续发展目标。结果如下：（1）人类住区质量呈上升趋势，PLE功能差异缩小。（2） 确定了一种空间布局，即东西部人类住区质量高，中部地区质量低，成都和重庆为两个高值核心区。（3） 人类住区质量水平实现跨越式转变具有挑战性，空间溢出效应和“俱乐部趋同”现象明显。（4） 生活功能是准则层的主要障碍，生产功能内的指标成为要素层的主要障碍因素。这些发现从城市群尺度上丰富了人类住区地理学的研究范围，为可持续发展目标提供了科学决策依据。
