摘要: 应用方差/均值比检验、波松分布的X2检验及负二项分布的X2检验3种方法,对比不同的取样样方,研究了椴树阔叶红松林群落主要树种的分布格局,并根据1hm2样地的定位图进行检验.研究结果表明,乔木树种的合适取样样方为5m×5m,其中红松、椴树、水曲柳、山槐、白牛子属于聚集型分布,蒙古栎、春榆属于随机分布.

Abstract: In this paper,variance/mean test,χ2 test of Poisson distribution and χ2 test of negative binomial distribution are used simultaneously to detect the distribution patterns of main tree species in Tilia broadleaf Korean pine forest sampled by two methods, and the results are tested by location drawing with sample size of 1 hm2. The results show that sampling with a size of 5 m×5 m is fit for arboreous trees. Pinus koraiensis,Tilia amurensis,Fraxinus mandshurica,Maackia amurensis and Acer mandshurica belong to an aggregate distribution,and Quercus mongolica and Ulmus propinqua to a stochastic one.
