摘　　要：探究生态治理背景下内陆河流域社区恢复力演变规律及其影响因素,对于流域生态保护与社会经济高质量发展具有重要意义。选取石羊河流域为典型研究区,在识别社区恢复力演变的基础上,探究社区恢复力内部影响因素及外部生态治理影响路径,进而揭示社区恢复力影响机制。结果表明:(1)生态治理背景下石羊河流域社区恢复力迅速增长且时空异质性明显,其中,生态维度空间格局集聚度高且优势性强,但增长缓慢,经济及社会维度时空异质性大,且增长迅速;(2)石羊河流域社区恢复力内部影响因素中,经济维度具有主导影响,社会维度影响减弱,而生态维度影响最小且变化趋势不大;(3)外部生态治理影响中,退耕还林及关井压田在三个时期对社区恢复力均起到制约作用,农业技术培训早期制约社区恢复力提升,后期制约作用消失,多重生态治理要素组合影响在2000年表现为农业结构调整及资源调控路径,2010年表现为农业结构调整路径、生活水资源主导调控路径、生态水资源主导调控路径,2020年表现为农业结构调整及资源配置路径、农业结构调整及技术支持路径、生产水资源主导配置路径。总体来说,研究为社区恢复力内外部影响因素综合研究提供了思路,也为内陆河流域未来乡村社区恢复力建设提供了实践参考。Analyzing the development and influencing factors of community resilience in the inland river basin against the background of ecological governance is crucial.In this study,we identified the evolution of community resilience in the Shiyang River Basin,analyzed the internal influencing variables and external ecological governance impacting paths of community resilience,and finally disclosed the influencing mechanism of community resilience.The results showed that:(1)The community resilience in Shiyang River Basin rapidly increased under ecological governance,and presented the significant temporal and spatial heterogeneity.The ecological dimension has been increasing slowly and the spatial pattern had high concentration and strong dominance.The economic and social dimensions developed rapidly,with obvious spatial and temporal heterogeneity.(2)Among the internal influencing variables of community resilience in the Shiyang River Basin,the economic dimension had the strongest influence,followed by the social dimension and the ecological dimension.(3)In terms of the externally ecological governance,the measures of converting farmland to forest,closing wells,and suppressing farmland limited the resilience of communities in three periods.The early implementation of the agricultural technology training also limited the improvement of community resilience,but its adverse effect faded in later periods.The influence of the combination of the multiple ecological governance factors showed the agricultural structure adjustment path and resource regulation path in 2000,followed by the agricultural structure adjustment path,domestic water resources regulation path,and ecological water resources regulation path in 2010,and the agricultural structure adjustment path,technical support path,and production water resource allocation path in 2020.In general,this paper provides ideas for the comprehensive study of the internal and external influencing factors of community resilience,and also provides practical reference for the future ru
