山东杂木林群落物种多样性与生态优势度分析

ANALYSIS ON THE SPECIES DIVERSITY AND ECOLOGICAL DOMINANCE OF SHANDONG COMPLEX FOREST COMMUNITY

应用Simpson指数和Shannon—Wiener指敷,研究分析了山东杂木林群落的物种多样性、均匀度以及生态优势度。结果表明:山东杂末林物种较为丰富,生态优势种不明显;物种多样性、均匀度与生态优势度大体呈负相关关系,它们均较好地表征了群落的综合特征;鲁东丘陵和鲁中南山地杂木林群落具有不同的物种多样性与生态优势度,反映了地理环境对植物群落的影响作用。

In this paper, Simpson index and Shannon—Wiener index are used to measure the species diversity, evenness of community and ecological dominance of Shandong complex forest. The results are as follows; The species are rich, the ecological dominant species are not obvious. There is a negative correlation between species diversity and ecological dominance as well as between evenness of community and ecological dominance, they can show the synthetic characteristic of the communities. There are different species diversity and ecological dominance between the hilly region of East Shandong and the mountainous region of middle-South Shandong, it shows the influence on communities by the geographical environment.
