Also, during this process, the water content in vegetation increases and keeps stable gradually, and the water environment in ecosystem will become suavely.

摘 要：本文以南亚热带常绿阔叶林为基本，同时探讨了热带南亚热带森林演替系列中8种生态系统类型的水分结构，发现植被水分结构的恢复与土壤水分结构的恢复是不同步的，50a以上没有受扰动的土壤，其土壤水分结构在时空上才趋于稳定；植被水分结构的时空稳定性基本上与生态系统的演替状况一致；为满足植被蒸腾的需要，植被中水分的月更新次数随着群落向顶极系统的演替而逐渐减少。

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。

Herbage is the principal part of the three forests both at its variety and number Especially in needle forest, the reserves of seed have distinct predominance The proportion of herbage seed in the bank are reduced, with the increasing of succession age Otherwise, the predominant components in the seed bank are different from the subaerial predominant vegetation at correspond layer.

草本植物不仅是种类还是数量上都是这三种林型土壤种子库的主体成分，特别是在针叶林中，种子储量占有十分显著的优势地位，随着演替年龄的增长，草本植物在种子库储量中占的比例有所减少。

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.

在1998—2000年三个生长季节内，通过对设立在森林区内26块研究样地及草原植被带内多状态下的11种群落类型中的亚气生藻类标本采集、培养、鉴定，中国东北森林-草原样带中共有亚气生藻类107种，隶属于蓝藻门、绿藻门及黄藻门的12科29属。

Mount Emei is also notable for its exceptionally diverse vegetation, ranging from subtropical to subalpine pine forests.

峨嵋山也是以其极多样的植物种类所闻名，范围可从亚热带至亚高山带的松树林。

In the vegetation of subalpine meadow zone, temperature is relative higher and there is local high temperature center in middle slope. Temperature is lower in slope foot, and the change of temperature grads is big.

在亚高山草甸带植被中，坡面中偏下部温度相对较高，往往会出现局部的高温中心；而坡面的底部普遍温度较低，且温度的梯度变化大。

The P.pratensis community is in the phase of herbs and forbs of degraded alpine meadow.At the same time the P.pratensis population is in the dominant spices position,subordinate spices position and company spices position.So,we can replant P.pratensis and other grass seed to change the structure and composition of plant community,improve community environment,cause it to develop to subclimax community succession,reach the stabler state.We can apply fertilizer,improve soil nutrition condition,enable degraded grassland with the link of soil and vegetation system together to reach the stabler subclimax and climax state.

草地早熟禾群落处于高寒草甸退化的禾草杂类草阶段，草地早熟禾种群在群落中处于优势种地位、次优势种地位和伴生种地位，因此，可通过补播草地早熟禾和其他禾草草种，改变植物群落结构和组成，改善群落环境，使其向亚顶级群落演替，达到较稳定的状态；也可通过撒施肥料，改善土壤养分状况，使土壤与植被系统共同作用将退化草地演替为较稳定的亚顶级或顶级状态。
