| 平原湖区作为典型的水陆交互敏感带，面临社会经济转型和水网生态约束的双重干扰，其乡村人地共生系统普遍陷入互害共生的治理困境。针对现有研究对平原湖区水网约束下聚落与耕地子系统互动关系与博弈阈值解析不足的局限，本研究以洞庭湖区为典型案例，构建乡村人地共生评价模型，基于Lotka-Volterra模型量化子系统的受力系数与共生度，划分出互利共生、互害共生、聚落偏利、耕地偏利四类共生模式，并系统识别影响人地共生系统的协同发展的障碍因素。研究发现：时序维度上，2000—2020年湖区乡村聚落与耕地子系统发展呈现结构性错配特征；共生模式以耕地偏利模式与互害共生模式为主导，揭示水网约束下资源竞争与系统损耗并存的人地共生模式。障碍因子解析表明，空间约束与结构失衡是抑制系统协同的核心瓶颈。综上，洞庭湖区应立足水网本底，优化空间结构和系统功能，促进乡村人地共生系统协调。 |

| As a typical water-land interaction-sensitive zone, the plain lake area is subject to dual disturbances from socio-economic transformation and ecological constraints imposed by dense water networks. Consequently, rural human-land symbiotic systems in these regions are often trapped in a dilemma of mutually detrimental interactions. To address this issue, and in view of the current research gap concerning the interaction mechanisms and threshold dynamics between rural settlements and arable land subsystems under hydrological constraints, this study selected the Dongting Lake region as a representative case. In this context, a rural human-land symbiosis evaluation model was constructed, in which the Lotka-Volterra model was employed to quantify subsystem force coefficients and symbiotic degrees. Based on this model, four types of symbiotic patterns：mutually beneficial symbiosis, mutually detrimental symbiosis, settlement-biased symbiosis, and arable land - biased symbiosis，were identified, and the key barriers to the coordinated development of the human-land system were systematically examined. The research findings were as follows：temporally, from 2000 to 2020, the development of rural settlement and arable land subsystems in the lake region exhibited a structural mismatch. The dominant symbiotic types were arable land-biased and mutually detrimental symbiosis, revealing a rural human-land symbiotic pattern characterized by the coexistence of resource competition and system depletion and under water network constraints. Obstacle factor analysis showed that spatial constraints and structural imbalance were the core bottlenecks hindering system coordination. In conclusion, this study deepens the understanding of the dynamic mechanisms in traditional human-land relationship research and offers a new analytical perspective for resolving the coordination challenges among multiple subsystems in plain lake regions. In summary, the Dongting Lake region should build upon its water network foundation to optimize spatial structure and system functions, thereby promoting the coordinated development of the rural human-land symbiotic system. |
