【目的】

明晰林龄、密度与细根、土壤养分的关系，为大青山区油松人工林的科学经营与管理提供理论依据。

【方法】

设置8种不同林龄、密度（幼龄林中密度、幼龄林高密度、中龄林低密度、中龄林中密度、中龄林高密度、成熟林低密度、成熟林中密度、成熟林高密度）的油松Pinus tabulaeformis人工林样地24块。采用根钻法，分2层（0～20、20～30 cm）采集细根样品及土壤样品，揭示不同林龄、密度下细根生物量、形态特征及其与土壤养分的关系。

【结果】

细根生物量、根长密度、根表面积密度皆集中在0～20 cm土层。在幼龄林随着密度的增加，细根表现出增长的趋势；在中龄林至成熟林，随着密度增加，细根表现为先增后降的趋势；细根总生物量、根长密度、根表面积密度皆在中龄林中密度达到最大值，分别为411.60 g/m²、830.87 m/m²、224.05 m²/m³。土壤有机质、全氮、全碳、碱解氮、速效磷含量与细根生物量、根长密度、根表面积密度呈正相关，而与细根比根长、比表面积呈负相关。

【结论】

对大青山油松人工林进行科学经营管理时，结合林龄与密度的协同影响，幼龄林阶段宜采用高密度种植模式，中龄林及成熟林阶段宜采用中密度种植模式，更有利于促进林木生长发育。

【Objective】

The fine root biomass and morphological characteristics of Pinus tabulaeformis plantation with different forest age and density in Daqing mountain of Hohhot City, Inner Mongolia were studied, and the relationship between forest age and density and fine roots and soil nutrients was clarified, so as to provide a theoretical basis for the scientific management of Pinus tabulaeformis plantation in Daqing mountain area.

【Method】

Twenty-four plots of Pinus tabuliformis plantations were established, comprising eight treatment types with different stand age classes and densities: young stands with medium density, young stands with high density, middle-aged stands with low density, middle-aged stands with medium density, middle-aged stands with high density, mature stands with low density, mature stands with medium density, and mature stands with high density. The root coring method was employed to collect fine root and soil samples from two depth layers (0-20 cm and 20-30 cm), investigating fine root biomass, morphological characteristics, and their relationships with soil nutrients under different stand ages and densities.

【Result】

The fine root biomass, root length density and root surface area density were concentrated in the 0-20 cm layer. In young forests, with the increase of density, fine roots showed an increasing trend. From middle-aged forest to mature forest, the fine roots showed a trend of increasing first and then decreasing with the increase of density. The total biomass, root length density and root surface area density of fine roots reached the maximum of 411.60 g/m², 830.87 m/m² and 224.05 m²/m³ at medium density in middle-aged forest. Soil organic matter, total nitrogen, total carbon, available nitrogen and available phosphorus content were positively correlated with fine root biomass, root length density and root surface area density, but negatively correlated with fine root specific root length and specific surface area.

【Conclusion】

In the scientific management of Pinus tabulaeformis plantation in Daqing mountain, combined with the synergistic effect of forest age and density, high-density planting mode should be adopted in the young forest stage, and medium-density planting mode should be adopted in the middle-aged forest and mature forest stage, which is more conducive to promoting the growth and development of trees.
