The factors which affect the difference of subaerial algae's distribution are summaried as follows:①The canopy density of community or coverage of community.

影响亚气生藻类在各植被带内分布差异的因素主要是:①地上植物群落的冠层郁闭度或盖度。

Otherwise, the predominant components in the seed bank are different from the subaerial predominant vegetation at correspond layer. The result showed that the growth of subaerial parts of plant community isn't obviously isochronous with the seed bank. So the inherent potential of soil seed bank has important influence on the regeneration of forest and the dynamic succession of plant community.

另外,种子库中优势成分与取样地点地面植被相应层次的优势种存在较大差异,说明植物群落地上部分的发育与其它地下部分的土壤种子库的发育具有明显的不同步性,这一结果表明土壤种子库的内在潜力对森林更新及植物群落演替动态产生了重要影响。

The article is primarily focused on the flora of subaerial algae of zonal vegetation in terrestrical ecosystem of NECT、subaerial algae's distribution regularity and the aspect both the natural and artificial disturbance which affect it's distribution.

本文着重研究了中国东北森林—草原样带中陆地生态系统中的各地带性植被内亚气生藻类的种类组成、亚气生藻类在各地带性植被内的分布规律及影响亚气生藻类分布的一些自然因素,同时也研究了某些人为干扰对亚气生藻类分布产生的影响。

A low level of disturbance can not bring the obvious changes to the subaerial algae in community interior, intermediate disturbance can increase the species quatities of subaerial algae, but can not change the dominant species of algae community, while the serious or repeated disturbance may alter both the component of species and the dominant species, that is species quatities decrease, and dominant species change.

局部小范围的干扰或轻度干扰不会对群落内部亚生藻类的种类组成产生明显影响;中度干扰可使群落内部的亚气生藻类的种类明显增加,但藻类群落的优势种不会改变;而重度干扰下,植物群落内的亚气生藻类的种类组成及优势种均会发生重大变化,种类数量减少,优势种改变。

During the growth season in the year 1998—2000, through collecting、culturing and identifing the subaerial algae which is in 26 research sites of forest and 11 communities of steppe vegetation, there are 107 species of subaerial algae in Jilin's terrestrial ecosystem which are subordinated to 12 families, 29 genus in Cyanophyta.
