摘要：Understanding the formation process and pattern of production–living–ecological spaces (PLES) is crucial for sustainable land-use management and adaptive city governance. However, previous studies have neglected the symbiotic relationships between land-use functions (LUFs) in identifying and optimizing PLES. To address this gap, this paper proposes a technical framework for assessing PLES from a LUF symbiosis perspective. A case study was conducted in Xiangyang City, China, to identify PLES and analyze its urban–rural differentiation using the symbiosis degree model and landscape pattern indices. Our findings revealed that the symbiotic relationships between LUFs varied. There were 25 combination types of PLES in Xiangyang City, with significantly varied area proportions and spatial distribution. The landscape types and fragmentation of PLES increased along with the gradient change from the old urban area to the rural area. Furthermore, we proposed a PLES optimization strategy involving LUFs symbiosis and the urban–rural gradient. Our study enriches the dimensions of PLES assessment and supports better-coordinated planning and the protection of PLES.摘要中译：了解生产-生活-生态空间的形成过程和模式对可持续土地利用管理和适应性城市治理至关重要。然而，以往的研究忽略了土地利用功能(LUFs)之间的共生关系。为了解决这一难题，本文提出了一个从LUF共生角度评估PLES的技术框架。以襄阳为例，利用共生度模型和景观格局指数对城市生态系统进行识别，并分析其城乡差异。我们的研究结果表明，LUF之间的共生关系各不相同。襄阳地区有25种不同类型的生态系统，其面积比例和空间分布差异显著。从旧城区到农村，景观类型和破碎化程度随梯度变化而增加。在此基础上，提出了一种考虑LUFs共生和城乡梯度的PLES优化策略。该研究丰富了生态环境评估的维度，为更好地协调规划和保护生态环境提供了支持。
