Social-ecological production landscape resilience (SELPR) is a significant representation of the continuous supply capacity of landscape services. It is a quantitative assessment of the spatial-temporal evolution of SELPR under internal and external disturbances that provides a scientific basis for regional ecological environments and socio-economic development. Taking Mizhi County for the study of the Loess Plateau region, a three-dimensional (social system, ecosystem, and production system) SELPR evaluation framework was constructed. Data integration was performed using the watershed as the evaluation unit. This study quantitatively evaluated the spatial-temporal differentiation of the social-ecological production landscape (SELPs) subsystem's resilience and the total SELPR in the study area and classified the areas from the three-system resilience combination level to achieve regional development trade-offs. The results were as follows: (1) In 2009-2018, the change in the social-ecological production landscapes pattern in Mizhi County showed a significant reduction in agricultural production landscapes, relatively stable social living landscapes, and an increase in ecological landscapes; (2) in 2009-2018, the SELPR increased by 12.38%. The spatial distribution of resilience was significantly different, showing a distribution pattern of high central and low surrounding areas; (3) the county's watershed development zones were divided into five partitions: synergistic promotion areas, ecological restoration areas, social development areas, production optimization areas, and comprehensive remediation areas. The five types of zones have a certain agglomeration effect. In addition, the main obstacle factors affecting the SELPR of each zone are quite different. The key issues and development directions of different types of watersheds are also proposed in this paper.
社会-生态生产景观弹性(SELPR)是景观服务持续供应能力的重要体现。它是对景观服务在内外干扰下的时空演变的定量评估,为区域生态环境和社会经济发展提供了科学依据。以陕北米脂县为例,构建了一个三维(社会系统、生态系统和生产系统)SELPR 评价框架。采用流域作为评价单元进行数据集成。本研究定量评价了研究区社会-生态生产景观(SELPs)子系统弹性和总 SELPR 的时空分异,并从三系统弹性组合水平对区域进行分类,实现了区域发展权衡。结果表明:(1)2009-2018 年,米脂县社会-生态生产景观格局变化表现为农业生产景观明显减少,社会生活景观相对稳定,生态景观增加;(2)2009-2018 年,SELPR 增加了 12.38%。弹性的空间分布差异显著,呈高中心、低周围的分布格局;(3)将县域流域发展带划分为协同促进区、生态修复区、社会发展区、生产优化区和综合整治区等 5 个分区。5 种类型的分区具有一定的集聚效应。此外,影响每个分区 SELPR 的主要障碍因素也大不相同。文中还提出了不同类型流域的关键问题和发展方向。
