Drawing from the United Nations Sustainable Development Goals (SDGs), this study offers a framework for optimizing rail transit routes, balancing economic benefits with environmental preservation. Using the Bivariate Choropleth-Multi-Criteria Decision Analysis (BC-MCDA) model, we categorize global regions into economic benefit, environmental conservation, high-conflict, and low-conflict zones. Specifically, 7.42% are identified as economic benefit zones, suitable for rail transit expansion with minimal environmental impact. Meanwhile, 16.14% are environmental conservation zones, requiring preservation and 76% are low-conflict zones, where maintaining existing land use is advised. Only 0.62% are high-conflict zones, demanding careful planning. Addressing how to utilize land more effectively and sustainably in transportation development to foster economic growth while avoiding harm to biodiversity and ecosystems, this study provides actionable insights. It advances sustainable transportation planning by integrating environmental and economic considerations, offering practical guidance for aligning infrastructure projects with global sustainability goals.
本研究借鉴联合国可持续发展目标（SDGs），提供了一个优化轨道交通线路的框架，在经济效益与环境保护之间取得平衡。我们使用双变量分级统计图 - 多标准决策分析（BC - MCDA）模型，将全球区域划分为经济效益区、环境保护区、高冲突区和低冲突区。具体而言，7.42%被确定为经济效益区，适合在对环境影响最小的情况下扩展轨道交通。同时，16.14%为环境保护区，需要加以保护，76%为低冲突区，建议维持现有土地用途。只有0.62%是高冲突区，需要谨慎规划。本研究探讨了如何在交通发展中更有效、可持续地利用土地，以促进经济增长，同时避免对生物多样性和生态系统造成损害，提供了可付诸行动的见解。它通过整合环境和经济因素推进可持续交通规划，为使基础设施项目与全球可持续发展目标保持一致提供了实际指导。
