摘要
在梅花山国家级自然保护区调查拟赤杨次生林,运用生态位重叠计量公式计算Lotka-Volterra竞争系数,比较竞争系数与K值比。结果表明:在调查群落中,拟赤杨在与其他伴生树种的竞争中目前处于优势地位,其他伴生树种有些可能被淘汰。
The interspecific competition among the dominant tree species in the Alniphyllum fortunei secondary forest in the Meihuashan Nature Reserve was studied by means of calculating Lotka-Volterra competition coefficients with niche overlapping measurement formulae, and by comparing the ratio values of competition coefficients and K values. The results indicated that A. fortunei occupied the predominant status in the competition with other accompanying tree species in the surveyed community, and some of the accompanying tree species might be eliminated gradually in the future.
