群落

Result showed that wild Styrax resources in Henan had 6 species,4 species of which were endemic to China.They were all community companion species distributed in southern mountainous areas of Henan.Styrax had characteristics such as drought tolerance,cold tolerance and strong seed viability.

研究结果表明：河南野生安息香属有6种植物，其中4种为中国特有种；经种群数量特征量化分析，属于群落伴生种；大多分布于豫南山区杂木林中，具有耐土壤干旱、耐寒、种子萌发力强等特点。

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。

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。

It is bigger that temperature impacts on the distribution of species in subalpine meadow zone landscape.

阳坡物种丰富的群落集中分布在相对高温区，阴坡则在相对低温区。

Results In this community,there were 9 species of 3 subgenera of 2 genera in subfamilies Anophelinae and Culicinae.

方法在水稻的不同生长期，采用容积为1000ml幼虫勺进行调查；数据输入计算机，进行统计学和群落学特征分析。

Changes in community structure over time are apparent from pollen analysis of sediment cores. Successional progress depends

群落结构随时间的变化从沉积物芯样的花粉分析来看是十分明显的。

Therefore, attention should be paid to both invasive species and native weeds in managing dominant herbaceous species in early successional communities.

因此，对演替早期群落中草本植物的控制与管理应同时注意外来入侵物种与本地杂草。

Some conclusions from the study on human driving factor are:(1) the human activity is much more active factor to the process of desertification which mainly incarnates on the changes of the landuse fashion (from traditional rangeland 100 years ago come to interlacing agro-pastoral region) and enhance of landuse intensity (over-cultivation, over-grassing and over-fuel collection);(2) the natural vegetation had been destroyed suicidally by human activities that had accelerated to the development desertification.

在人为驱动力的分析中，得到以下一些初步的结论：（1）人类活动是本地区沙漠化过程中更加活跃的驱动因子，体现在土地利用方式的转变（从传统的牧业草原到今日的农牧交错区）和强度的增加（过度开垦、放牧、樵采等）；（2）由此对自然植被群落毁灭性的破坏，加速沙漠化的进程。

The distribution of supertramp bird species on islands also supports the theory that communities are structured by competition.

岛屿上超飘流的鸟类物种的分布也支持了该理论，即竞争导致了群落的结构化。

It 's not surprising to find successful symbiotic teams operating there.

在那里看到成功的共生群落一点也不奇怪！
