生态脆弱区乡村人居环境系统韧性特征及影响因素分析
CHARACTERISTICS AND INFLUENCING FACTORS OF RURAL HUMAN SET-TLEMENT SYSTEMS IN ECOLOGICALLY FRAGILE AREAS
摘要
Abstract
To reveal the evolutionary characteristics of internal pressure,state and response of the resilience of rural human settlement systems in ecologically fragile areas under the combined action of multiple external pressures,as well as the spatiotemporal heterogeneity and action mechanism of its influencing factors,this research constructed a measurement index system for the resilience of rural human settlement systems in ecologically fragile areas.Taking the county-level regions of the Loess Plateau in Northern Shaanxi as the research object,it evaluated and analyzed the spatiotemporal evolution of system resilience and its internal pressure,state and response from 2006 to 2021.Furthermore,it adopted the Tobit model and Geographically and Temporally Weighted Regression(GTWR)model to explore the evolutionary process of spatiotemporal heterogeneity and the corresponding action mechanism of the factors influencing resilience.The results showed that:(1)From 2006 to 2021,the resilience of rural human settlement systems on the Loess Plateau in Northern Shaanxi increased from 9.196 to 10.814 with a slow growth rate;the external representation of its spatial distribution pattern became increasingly distinct,forming an overall pattern of high in the northwest and low in the southeast.There were significant spatiotemporal differences in the resilience of rural human settlement systems on the Loess Plateau in Northern Shaanxi as well as its internal pressure,state and response subsystems.(2)The annual pressure and state indices of each internal subsystem were consistent with the spatial pattern of system resilience,and their levels were both higher than that of the response index.The pressure and state indices of each subsystem rose slowly with fluctuations or remained stable,while the response index stayed at a persistently low level.All subsystems were confronted with constant pressure threats and insufficient response capacity,resulting in a slow improvement of the overall state of the systems.(3)Eight indicators across three dimensions(ecological quality,economic development,spatial pattern)significantly influenced the rural human settlement system resilience in the Northern Shaanxi Loess Plateau,including ecological level,regional economic level,and six spatial pattern-related indicators(living/ecological space fragmentation degree,living space agglomeration degree,living/ecological/production space morphology index).Living space fragmentation degree had the highest contribution,with all spatial pattern factors contributing relatively highly.Notably,the positive impacts of ecological quality and spatial pattern continued to strengthen,while economic development's contribution declined.(4)The system resilience is jointly driven by economic development,ecological quality,and spatial pattern:ecological quality improvement is the primary basic condition,regional economic development the internal driving force,and spatial pattern optimization the key path.These three synergistically promote the cyclic evolution of system resilience.In summary,by revealing the spatiotemporal heterogeneity and influencing factors of the resilience of rural human settlement systems on the Loess Plateau in Northern Shaanxi,this study provides guidance for regional resilience improvement and sustainable development,and lays a solid foundation for subsequent research on the interaction of subsystems,improvement of index systems and spatial planning paths.关键词
