摘要：【目的】通过监测油松种群和群落动态,为华北地区人工林质量提升和生物多样性研究提供基础数据支持。【方法】以北京百花山自然保护区油松林为研究对象,选择50年生人工林建立5.2hm2动态监测样地,参考中国森林生物多样性监测网络的统一标准,对样地内胸径≥1cm的所有木本植物进行了挂牌、调查和统计,分析样地内木本植物的物种区系、径级组成及空间分布格局。【结果】样地内胸径≥1cm的木本植物共计9242株,其中活立木7145株,隶属15科22属23种。其中,66.66%的科和63.64%的属具有温带植物区系的特点。有5个物种的重要值>5%,分别为油松、槲树、黑桦、土庄绣线菊和华北落叶松,其重要值总和95.44%,稀有种和偶见种分别有8种和10种。优势种的种群空间分布格局以聚集分布为主。【结论】百花山油松人工林动态监测样地物种多样性较高,油松自疏过程为其他先锋树种提供生态位,导致群落优势种群空间分布呈聚集模式。本研究为后续开展油松人工林质量精准提升和多样性维持机制研究提供本底数据支撑。
[Objective]By monitoring the dynamics of Pinus tabuliformis populations and their associated communities,we aim to provide foundational data that will support improvements in plantation quality and advance biodiversity research across North China.[Method]This paper focuses on P.tabuliformis forest in the Beijing Baihua Mountain Nature Reserve,where a 5.2 ha dynamic monitoring plot was established in a 50-year-old plantation.All woody plants with DBH≥1 cm in the plot were tagged,surveyed,and inventoried following the standards of China Forest Biodiversity Monitoring Network.The study analyzed the floristic compositions,diameter class structures,and spatial distribution patterns of woody plant species in the plot.[Result]A total of 9242 individuals with DBH≥1 cm were recorded in the plot,including 7145 living trees which belong to 15 families,22 genera and 23 species.The floristic composition of these species exhibited typical characteristics of temperate flora,with 66.66%of the families and 63.64%of the genera possessing temperate components.Five species had importance values>5%,namely P.tabuliformis,Quercus dentata,Betula davurica,Spiraea ouensanensis,and Larix gmelinii var.principis-rupprechtii,which took account for 95.44%of the overall importance values.The number of rare and accidental species was 8 and 10,respectively.The spatial distribution patterns of dominant species were primarily aggregated.[Conclusion]Species diversity is relatively high for P.tabuliformis plantation dynamic plot in the Baihua Mountain.The self-thinning process of P.tabuliformis provides niches for other pioneer tree species,which resulting in spatial aggregated patterns of dominant populations in the community.This study provides baseline data for future research on precision improvement in quality and the mechanisms that sustain biodiversity in P.tabuliformis plantations.
