摘要
基于奇乾山地樟子松群落的野外调查,分析了奇乾樟子松群落特征、种群空间分布格局以及物种多样性分布规律。结果表明:(1)奇乾山地樟子松林密度分别为830株/hm2、780株/hm2、580株/hm2。樟子松群落直径分布为单峰和多峰分布,树高分布为单峰山状和多峰山状分布2种形式;(2)奇乾山地樟子松3块样地种群分布格局均为聚集分布;(3)奇乾山地樟子松群落丰富度指数为:草本层>乔木层>灌木层,多样性指数规律:草本层>灌木层>乔木层,均匀度指数无明显规律。
Based on field investigation of Pinus sylvestris var. mongolica in Qiqian, the community structure, distri- bution patterns and species diversity of Pinus sylvestris var. mongolica community have been analyzed. The results showed： （1） The density of Pinus sylvestris var. mongolica forest are 830 stocks/hm2, 780 stocks/hm2, 580 stocks/hm2. The diameter distribution is in unimodal and muhimodal distribution, the height distribution is in uni- modal mountain and multi -peak shape distribution. （2） The distribution patterns of three sample plots in Qiqian are aggregated distribution. （3） The richness index of Pinus sylvestris var. mongolica community is herb layer 〉 ar- bor layer 〉 shrub layer, the diversity index of Pinus sylvestris var. mongolica community is herb layer 〉 shrub layer 〉 arbor laver, and the law of evenness index isn＇ t obvious.
