摘  要：
乔木层是侧柏人工林生态系统的重要组成部分,其质量优劣决定了生态系统的稳定性。以鲁中山地3处样地的23个典型侧柏人工林为研究对象,通过野外调查和室内分析,采用因子分析法研究了侧柏林乔木层的综合质量,并探讨了影响乔木层质量的主要因子。结果表明,不同样地侧柏乔木层质量存在较大差异,以原山林场2号、燕子山林场5号、原山林场3号、黑峪林场5号和黑峪林场7号等5个样地侧柏林乔木层质量较好;而燕子山林场6号、1号和黑峪林场2号相对较差。相比之下,位于原山林场的侧柏林乔木层整体质量较好,各林分间变异最小,整体更为稳定。在14个评价指标中,树高、胸径、材积、年均生物量、冠幅、冠层高、叶面指数和密度等8个指标分别与乔木层质量综合分值之间存在显著性相关;随着林分密度的增加,侧柏林乔木层质量显著降低。

摘  要：
Arbor layer is an important part of Platycladus orientalis plantation ecosystem, whose quality determines the stability of ecosystem. In this paper, 23 typical Platycladus orientalis plantations in three sample plots in the central mountainous regions of Shandong province were studied. Through field investigation and indoor analysis, the comprehensive quality of the arbor layer of Platycladus orientalis planatations was studied by factor analysis, and the main factors affecting the quality of the arbor layer were discussed. The results showed that the quality of arbor layer of Platycladus orientalis was quite different among different sites. The arbor layer quality of five plantations, i.e. Yuanshan Forest Farm No.2, Yanzishan Forest Farm No.5, Yuanshan Forest Farm No.3,Heiyu Forest Farm No.5 and Heiyu Forest Farm No.7, was better than the others. However, the arbor layer quality of Yanzishan Forest Farm No.6, No.1 and Heiyu Forest Farm No.2 was the worse. In contrast, the overall quality of arbor layer in Yuanshan forest farm is better than the other two, the variation among the stands is the smallest, and the whole is more stable. Among the 14 evaluation indexes, 8 indexes, such as tree height, DBH, volume, annual biomass, crown width, canopy height, leaf index and stand density, were significantly correlated with the comprehensive scores of arbor layer quality. With the increase of forest density, the quality of arbor layer decreased significantly.
