| 油松作为吕梁山生态脆弱区分布最广、面积最大的主要造林树种之一,对区域水土保持、水源涵养和生态系统稳定具有重要作用。为科学评估山西省吕梁山生态脆弱区油松人工林退化修复成效,在系统分析该区域立地条件、油松分布格局与生态功能重要性的基础上,基于油松生长规律及退化修复目标,从林分结构、生态功能、土壤质量和修复成效4个维度构建包含22项具体指标的油松人工林退化修复核查指标体系,采用层次分析法确定各指标权重,并通过实地调查、遥感监测与实验室分析相结合的方法,在吕梁山生态脆弱区选取3个典型修复区域(离石区,轻度退化;中阳县,中度退化;交口县,重度退化)共15块样地进行核查应用。结果表明,该指标体系综合评分与修复实际成效高度契合,H1~H5样地、H6~H10样地、H11~H15样地综合修复等级分别为“良好”(82.30分)、“中等”(71.50分)、“一般”(63.80分);林分郁闭度、植被覆盖度、土壤有机质含量、幼苗成活率等核心指标权重占比达59.3%,是影响修复成效的关键因素。本研究构建的指标体系可为吕梁山及同类生态脆弱区油松人工林退化修复核查提供标准化工具,为优化修复技术方案、提升生态治理成效提供科学依据。 |

| Pinus tabuliformis, as one of the most widely planted tree species with the largest area in the ecologically fragile zone of the Lüliang Mountains, plays an important role in regional soil and water conservation, water source conservation and ecosystem stability. To scientifically evaluate the restoration effectiveness of degraded P.tabuliformis plantations in the Lüliang Mountains of Shanxi Province, this study systematically analyzed site conditions, spatial distribution and ecological functions of P.tabuliformis stands. According to tree growth characteristics and restoration objectives, a verification index system with 22 indicators was established from four dimensions: stand structure, ecological function, soil quality and restoration performance. The analytic hierarchy process (AHP) was used to calculate indicator weights. Combined with field surveys, remote sensing monitoring and laboratory tests, the index system was verified in 15 sample plots across three typical restoration regions: Lishi District (lightly degraded), Zhongyang County (moderately degraded) and Jiaokou County (severely degraded). The results showed that the comprehensive evaluation scores were highly consistent with the actual restoration effects. Plots H1-H5 were rated as good with an average score of 82.30, plots H6-H10 as moderate with 71.50, and plots H11-H15 as fair with 63.80. Key indicators including stand canopy density, vegetation coverage, soil organic matter content and seedling survival rate accounted for 59.3% of the total weight, which were the primary factors controlling restoration outcomes. The established index system can serve as a standardized tool for verifying the restoration of degraded P.tabuliformis plantations in the Lüliang Mountains and similar ecologically fragile regions, and provide support for optimizing restoration techniques and improving ecological management. |
