摘要

生态复原力评估已成为城市可持续治理的关键环节。本研究引入了一个新的评估框架，为政策制定和实际应用提供依据。它以景观格局的结构和功能维度为基础，整合了复原力的脆弱性、敏感性和自组织性，指出了生态复原力的理想方向。根据景观多样性、景观干扰、源-汇斑块距离、栖息地质量、最小累积阻力和景观恢复六项指数，编制了生态复原力综合指数。该框架尤其适用于位于生态敏感地区的城市。因此，中国南昌市被选为案例研究对象。利用 1 平方公里的六边形网格，该框架被应用于绘制南昌市 2000 年至 2020 年的时空变化图，并分析生态恢复力的各种自然和人为驱动力。研究结果证实了城市生态复原力分析框架的可行性和价值。研究结果证实了城市生态复原力分析框架的可行性和价值，并强调了该框架在揭示空间动态过程和生态复原力促成因素方面的优势，使其成为可持续城市规划和精细化管理决策的宝贵实用工具。

The evolution of urban ecological resilience: An evaluation framework based on vulnerability, sensitivity and self-organization

Ecological resilience assessment has become a key link in urban sustainable governance. This study introduces a new evaluation framework to inform policy-making and practical applications. Based on the structural and functional dimensions of landscape patterns, it integrates the vulnerability, sensitivity and self-organization of resilience to point to desirable directions of ecological resilience. A composite ecological resilience index is compiled based on six indices of landscape diversity, landscape disturbance, source-sink patch distance, habitat quality, minimum cumulative resistance, and landscape restoration. The framework is particularly applicable to cities located in ecologically sensitive areas. Hence, Nanchang City, China was selected as a case study. Using 1km² hexagonal grids, the framework is applied to map spatiotemporal changes and to analyze various natural and anthropogenic driving forces of ecological resilience in Nanchang from 2000 to 2020. Research findings confirm the feasibility and value of the urban ecological resilience analysis framework. They also highlight the advantages of the framework in revealing spatially dynamic processes and ecological resilience contributing factors, making it a valuable and practical tool for sustainable urban planning and refined management decision-making.

The journal welcomes cross-cutting, multi-disciplinary research in various areas, including: 1. Smart cities and resilient environments; 2. Alternative/clean energy sources, energy distribution, distributed energy generation, and energy demand reduction/management; 3. Monitoring and improving air quality in built environment and cities (e.g., healthy built environment and air quality management); 4. Energy efficient, low/zero carbon, and green buildings/communities; 5. Climate change mitigation and adaptation in urban environments; 6. Green infrastructure and BMPs; 7. Environmental Footprint accounting and management; 8. Urban agriculture and forestry; 9. ICT, smart grid and intelligent infrastructure; 10. Urban design/planning, regulations, legislation, certification, economics, and policy; 11. Social aspects, impacts and resiliency of cities; 12. Behavior monitoring, analysis and change within urban communities; 13. Health monitoring and improvement; 14. Nexus issues related to sustainable cities and societies; 15. Smart city governance; 16. Decision Support Systems for trade-off and uncertainty analysis for improved management of cities and society; 17. Big data, machine learning, and artificial intelligence applications and case studies; 18. Critical infrastructure protection, including security, privacy, forensics, and reliability issues of cyber-physical systems. 19. Water footprint reduction and urban water distribution, harvesting, treatment, reuse and management; 20. Waste reduction and recycling; 21. Wastewater collection, treatment and recycling; 22. Smart, clean and healthy transportation systems and infrastructure;
