| 摘 要： | 地球演化引起物质分异加上人类活动使元素在地表的分布很不均匀.从局部到全球,地球化学异常分布具有谱系模式.元素不仅是生物的基本组成物质,而且在生命活动中起着复杂而重要的作用.生物与其生存环境的协调平衡是生物演化和发展的基本准则,因此,元素地球化学异常的谱系分布模式对应着相应的生物作用和生态效应.本文初步探讨了不同级次地球化学异常的生态环境效应特征.

| Abstract: | Geochemical distribution of elements in the surficial media is not homogeneous,and a hierarchy of chemical patterns has been indicated by Xie Xuejin et al. (1993). It is commonly known that chemical elements not only serve as the components of biomass, but also take part in bioactivities in a variety of mechanisms. This paper makes a preliminary discussion on the environmental ecological effects of geochemical anomalies of different grades. |
