摘要:

生态系统服务功能与生态系统敏感性是衡量生态系统质量及实现高质量生态文明建设的重要依据。川藏铁路沿途跨越多个自然地理单元,生态环境保护是铁路规划、建设及运行过程中面临的关键问题。以川藏铁路西藏昌都段为研究对象,采取资料分析与野外调查结合的手段,运用生态评价模型对研究区的生态系统服务和生态脆弱性进行分析,并基于研究结果对铁路途经区域的生态保护重要性进行评价。结果表明,当前昌都境内川藏铁路涉及的生态保护极重要区、重要区和一般重要区占比分别为42.19%、52.69% 和5.12%。评价结果有助于在铁路规划、建设及运营过程中对工程活动进行合理布局,有针对性地降低对生态系统的负面影响,达到社会经济效益和生态效益双赢的目的。

关键词: 川藏铁路, 生态系统服务功能, 生态脆弱性, 生态系统保护重要性

Abstract:

The Sichuan-Tibet railway extends across many geographical units, which is of great ecological protection significance. Effective protection of the ecological environment along the railway is a key issue during the process of railway planning, construction, and operation. In this study, the Changdu section of the Sichuan-Tibet railway is studied. The ecosystem service function and sensitivity are important in measuring the quality of ecosystem and establishing high-quality ecological conservation protocols. This study integrated data analysis and field investigation, and evaluated the ecosystem service and ecological vulnerability of the research area through ecological evaluation modelling, and evaluated the importance of the ecological protection along the railway line based on the research results. The results show that the percentage of the most important, important, and generally important ecological protection areas along the Changdu section is 42.19%, 52.69% and 5.12%, respectively. The evaluation results can assist engineering activity planning during the railway design, construction, and operation, and reduce the negative impact on the ecosystem in a targeted way, and achieve a win-win scenario for the social, economic, and ecological benefits.

Key words: Sichuan-Tibet railway, ecosystem service function, ecological vulnerability, importance of ecosystem protection
