摘要: <正>2000~2002年在云南省红河州屏边县对北美红杉幼林进行了不同肥料(尿素、过磷酸钙、氯化钾)的施肥试验(共进行了8个处理,3次重复的随机区组设计)。结果表明:施肥使北美红杉幼林生物量增加,其中处理7(P1K2)能明显增加北美红杉幼林各器官及林木总的生物量;施肥能促进根和叶的生长,增加根系对磷的吸收,提高北美红杉幼林叶和根部磷的含量及贮量;叶和根部成为北美红杉磷素的主要贮存库。

Abstract: The paper is based on ordinary index to assess hiodiversity. Entropy is an important object to study. Entropy and other biodiversity indexes is used to assessed wilderness vegetation of Kelamayi in Xinjiang. The result shows entropy and other biodiversity indexes have corresponding in principle. Entropy is not only a fine assessed index as species diversity,ecological dominance and species richness but also manliest species of system which contributes to and evolutes to the system. The paper provides the new base to the assessment index of biodiversity.
