杉木老龄林群落的种-多度关系研究
|
摘要
以杉木老龄林群落为研究对象,结合对数级数和对数正态分布模型,建立3 600 m2的大样地分析杉木老龄林群落的种-多度关系。结果表明:样方的平均物种数和个体数分别为6.86种和35.75株,各样方的物种数及个体数存在极显著正相关关系,说明杉木老龄林群落中生境空间对物种个体的承载能力,还未限制其物种数量。个体数-种序(p>0.05)和频度-种序(p>0.05)的分布曲线均符合对数级数分布;对数正态分布模型则能够较好拟合个体数-种序(p>0.05)的分布曲线,但频度-种序(p<0.05)的分布曲线则不适合用该模型来解释。随着尺度的增加,物种数和个体数的变异系数、二者间的相关性及物种数的方差逐步下降,个体数的方差却呈上升的趋势。
In order to investigate the species abundance in aging fir forest community, a 3 600 m2 forest plots in the core zone were established based on the two species abundance statistical models(log-series distribution model( LSD) and log-normal distribution model( LN). The results showed that: the overall average number and individuals number of plots species were 6.86 and 35.75, there was a significant positive correlations between species number and individuals number of each plot, indicating that aging fir forest community yet to limit their number of species in carrying capacity of habitat space for individual species. The curve of individuals-species rank distribution(p>0.05) and frequency-species rank distribution(p>0.05) are in line with LSD; LN is able to fit the individuals-species rank distribution, but not suitable for the frequency-species rank distribution. Variation coefficient and correlation between species and individuals as well as the ariance of species linearly decreased with the increasing scale, whereas the ariance of individuals number is an upward trend.
