Strip harvesting can improve the management of low‐quality forests, but the practice affects forest soil properties and microbial communities. The effects of different strip widths on the physicochemical properties of the forest soil and the bacterial diversity were determined. The design consisted of four strips with the same length and different widths of 6 m (ZM6), 10 m (ZM10), 14 m (ZM14), and 18 m (ZM18) and an unharvested strip (ZM0) as the control. Illumina high‐throughput sequencing was used to determine the sequence information of the soil microbial community structure in the five strips. The dominant bacterial phyla were Proteobacteria and Acidobacteria, while the dominant bacterial genera were AD101, Rhodoplanes, and Bradyrhizobium. The strip width exhibited a highly significant positive correlation with Proteobacteria and Acidobacteria (p < .001). The order of plots based on soil bacterial diversity (Chao1 and the abundance‐based coverage estimator [ACE]) was ZM18 > ZM10 > ZM6 > ZM14 > ZM0, and there was a highly significant positive correlation between the indices and the strip width (p < .001). Strip harvesting significantly affected soil pH, total nitrogen (TN), total potassium (TK), soil respiration (SR), soil temperature (ST), and soil moisture (SM) (p < .05). The results of a principal component analysis (PCA) showed that strip harvesting explained 23% of the bacterial variation. The 10‐m‐wide strip exhibited the most desirable effects because it had relatively rich bacterial diversity and moderate soil fertility.

剥采对大兴安岭森林土壤细菌多样性的影响

条状采伐可以改善对劣质森林的管理，但是这种做法会影响森林的土壤特性和微生物群落。确定了不同条带宽度对森林土壤理化性质和细菌多样性的影响。设计由四个长度相同，宽度不同的条带组成，分别为6 m（ZM6），10 m（ZM10），14 m（ZM14）和18 m（ZM18），一条未收割的条带（ZM0）作为对照。Illumina高通量测序用于确定五个条带中土壤微生物群落结构的序列信息。优势菌门是Proteobacteria和Acidobacteria，而优势菌属是AD101，Rhodoplanes和Bradyrhizobium。条带宽度与变形杆菌和酸性细菌表现出高度显着的正相关（p  <.001）。基于土壤细菌多样性的地块顺序（Chao1和基于丰度的覆盖率估算器[ACE]）为ZM18> ZM10> ZM6> ZM14> ZM0，并且指数与条带宽度之间存在极显着的正相关性（p  <.001）。剥采对土壤的pH，总氮（TN），总钾（TK），土壤呼吸（SR），土壤温度（ST）和土壤水分（SM）有显着影响（p <.05）。主成分分析（PCA）的结果表明，条带收割解释了23％的细菌变异。10米宽的条带显示出最理想的效果，因为它具有相对丰富的细菌多样性和中等的土壤肥力。
