摘　　要：草原生态修复是退化草原可持续利用与高质量发展的重要途径。科学的草原生态修复效果评估可为判断生态修复措施优劣和制定后续生态修复方案提供重要依据,但目前相关研究主要局限于对单一指标或几项指标(如生物量、植被盖度等)修复前后效果的比较,综合评价草原生态修复效果的研究相对较少。针对该问题,本研究采用因子分析法综合评价内蒙古陈巴尔虎旗退化草原的8种修复方式和9个草原生态修复效果评价指标,筛选具有代表性的群落评价指标和适宜的修复方式。结果表明:植被盖度、地上生物量和群落物种丰富度3个指标可作为评价修复效果的代表性指标,围栏+切根+施肥+管护是该区域的最佳生态修复方式。本研究使用的综合定量评估方法具有合理性和科学性,研究方法和结果为内蒙古退化草原及类似条件下的退化草原修复效果评估和修复管理提供了科学依据。Grassland restoration is a critical pathway toward achieving sustainable utilization and highquality development goals for degraded ecosystems.While scientific evaluation of restoration outcomes provides essential evidence for optimizing rehabilitation strategies,current methodologies predominantly focus on pre-and post-restoration changes in individual or limited indicators(e.g.,biomass,vegetation coverage),with insufficient attention to comprehensive multi-indicator assessments.To address this issue,this study used factor analysis to comprehensively evaluate eight restoration approaches and nine ecological restoration effect assessment indicators for degraded grasslands in Chen Barag Banner,Inner Mongolia,aiming to identify representative community assessment indicators and suitable restoration approaches.The findings demonstrated that:(1)Three critical indicators-vegetation coverage,aboveground biomass,and community species richness-were identified as representative metrics for restoration evaluation.(2)The integrated approach combining fencing with root pruning,fertilization,and sustained management practices demonstrated superior restoration effectiveness.Our comprehensive quantitative assessment methodology exhibited both scientific rigor and practical applicability.These findings provide an evidence-based framework for evaluating and managing grassland restoration initiatives in Inner Mongolia′s degraded steppes and comparable ecoregions.
