    摘要:

    面对西安都市圈发展过程中出现的生态空间碎片化问题,生态功能完善的需求及区域高质量一体化的发展目标,通过分析西安都市圈生态空间景观格局,提取其结构特征进而构建区域生态网络。利用形态学空间格局等方法提取西安都市圈生态空间结构特征,通过植被覆盖演变分析并识别潜在的具有生态功能的用地,通过设计转化阻力指标体系获得区域生态网络的构建基础。提出网络整合、廊道桥接、网络织补、生态修复4种生态网络整合策略。通过分析生态空间结构发现都市圈的生态斑块、廊道等不同类型生态功能区的分布特点,针对都市圈尺度提出多中心生态网络的规划模式,针对重要生态单元提出“核心—廊道—缓冲区”的规划模式,基于不同的整合策略调整生态用地布局及空间结构,以提高生态网络的连通性与稳定性,构建都市圈生态网络。聚焦生态空间结构演变机制分析、生态网络构建技术路径及模式探索,提出西安都市圈的生态空间结构,为生态空间规划提供新思路和新方法,这对于推动中国都市圈发展迈向更高水平具有积极意义。

    Abstract:

    Faced with the issue of fragmentation in the development of the ecological space, the demand for enhanced ecological functionality, and the goal of achieving high-quality regional integration of the Xi’an metropolitan area. This study analyzes the ecological spatial pattern of the research area to extract its structural characteristics and construct a regional ecological network. This study primarily employs the Morphological Spatial Pattern Analysis (MSPA) method to conduct research based on extracting ecological structural features. It further examines the evolution of vegetation cover dynamics for identified potential space with ecological functions. It employs a resistance index system to establish the foundation for constructing the regional ecological network. The research proposes four strategies for ecological network integration: network consolidation, corridor bridging, network patching, and ecological restoration. Analyzing spatial and resource structures identifies ecological patches and corridors’ types and distribution characteristics. At the regional scale, a multi-center ecological network model is proposed. At the mesoscale, a “core-corridor-buffer zone” model is suggested. Adjusting the layout and spatial structure of ecological space based on different integration strategies to enhance the connectivity and stability of the ecological network, thereby constructing a metropolitan ecological network. Finally, this study’s main conclusion focuses on analyzing the ecological space structural evolution mechanism, the technical pathways for ecological network construction, and model exploration. It presents the ecological space structure of the Xi’an metropolitan area, offering new ideas and methods for ecological space planning. These research findings have significant theoretical and practical implications for advancing the development of urban regions to a higher level.
