【摘要】 针对我国西北地区的重要生态屏障塔里木河流域，面临生态系统退化、水资源短缺和生物多样性减少等突出问题，从生态系统服务功能、生态脆弱性和生物多样性3个主要方面构建了生态保护重要性评价体系，结合区域发展潜力和资源可获得性进行生态保护重要性分级，并对该区域的生态修复优先序进行识别。研究结果表明，塔里木河流域的生态修复区可分为6级。其中，高保护区主要集中在流域的东北部和南部，财政状况较好的区域应加大修复投入，而财政较差的区域则应结合实际情况稳步推进修复工作。研究认为，高保护区应优先投入更多资源进行修复；中、低保护区则需要结合当地财政状况和实际条件，采取逐步推进的方式进行生态修复。更多还原

【Abstract】 The Tarim River Basin is a crucial ecological barrier in northwest China. Scientifically identifying the degradation of ecosystems in this region and conducting priority research on ecological restoration is essential to provide a scientific basis for resource optimization, ecological protection, and sustainable development in the Tarim River Basin. This study constructed an ecological protection importance evaluation system from three key aspects: ecosystem service functions, ecological vulnerability, and biodiversity. The importance of ecological protection was classified based on regional development potential and resource availability, and the priority of ecological restoration in the area was identified. The results show that the ecological restoration areas in the Tarim River Basin can be divided into six levels. The high-priority protection zones are mainly concentrated in the northeastern and southern parts of the basin. Regions with better financial conditions should increase restoration investment, while those with poorer financial conditions should proceed with restoration work steadily according to local circumstances. The study suggests that high-priority protection zones should receive more resources for restoration, while medium-and low-priority zones should gradually implement restoration efforts based on local financial conditions and practical circumstances.更多还原
