摘　　要：于太岳山某油松林区开展试验,根据不同森林经营模式选取目标树经营模式(S)、综合抚育经营模式(T)、无干扰经营(CK)样地,分析了不同森林经营模式对太岳山林区油松天然公益林的影响。结果表明:S经营模式油松天然公益林Shannon-Wiener多样性指数、Simpson优势度指数、Pielous均匀度指数、Margalef丰富度指数较CK模式,分别是其1.46倍、1.49倍、1.06倍、1.31倍;S经营模式下的油松天然公益林林下更新幼苗地径和树高较CK处理,分别是其1.24倍和1.33倍;S经营模式下的油松公益林健康小班个数显著高于其他两种模式(P<0.05);不健康的油松公益林小班个数显著少于其他两种模式(P<0.05);S经营模式下的速效氮、速效磷、速效钾含量较CK处理,分别是其1.32倍、1.48倍和1.15倍。不同森林经营模式对太岳山林区油松天然公益林产生不同程度的影响,经各经营模式对比,以目标树经营模式下的太岳山林区油松天然公益林林下物种较为丰富、林下更新优势更明显,营林效果较好。研究结果可为太岳山林区油松天然公益林可持续发展提供参考和借鉴。The experiment was carried out in a Pinus tabulaeformis Carrière forest area in Taiyue Mountain,and the target tree management model(S),comprehensive tending model(T)and non-interference management model(CK)were selected according to different forest management models to analyze the effects of different forest management models on the natural commercial forest of Pinus tabulaeformis Carrière.Shannon-Wiener diversity index,Simpson dominance index,Pielous evenness index and Margalef richness index of S management mode were 1.46 times,1.49 times,1.06 times and 1.31 times,respectively,compared with CK mode.Compared with CK treatment,the ground diameter and tree height of the regeneration seedlings under S management mode were 1.24 times and 1.33 times,respectively.The number of healthy small classes in the S-management mode was significantly higher than that in the other two modes(P<0.05).The number of small classes in unhealthy Pinus tabulaeformis Carrière was significantly lower than that in the other two modes(P<0.05).Compared with CK treatment,the content of available nitrogen,available phosphorus and available potassium in S management mode was 1.32 times,1.48 times and 1.15 times,respectively.Different forest management models have different degrees of impact on the natural public service forest of Pinus tabulaeformis Carrière in Taiyue Mountain forest area.By comparing the management models,the understory species of Pinus tabulaeformis Carrière natural public service forest in Taiyue Mountain forest area is more abundant;the advantage of understory regeneration is more obvious,and the forest management effect is better.The research results can provide a reference for the sustainable development of the natural commercial forest of Pinus tabulaeformis Carrière in Taiyue Mountain.
