群落

The dominant species in the tree layer were found as Castanopsis chinensis, Endospermum chinense and Cryptocarga concinna . The Mesophanerophytes and Microphanerophytes were found having high percentage, and the Megaphanerop, Geophytes and Therophytes were notfound in the species life form spectrum of the community. The Mesophyll also had high Percentage in leaf-sizeclass spectrum of the community.

本群落以中、小高位芽植物占优势，缺乏大高位芽、隐芽和一年生植物叶型以中型叶为主群落的大部分优势种的种群分布格局是随机分布的优势种群的立木结构分析表明，本群落处于进展演替它与30a前比较有较大的变化乔木层原优势种黄桐、猴耳环、亮叶肉实等被锥粟、刺栲等替代。

On nutrition strcture in arthropod community,function groups on every nutrition level were similar between Pb29 and CK,but in Pb29 leaf-eating pest on bascal species largely decreased,the rate of intermediate species increase ,top species have no obviously changing.

在节肢动物群落的营养结构中，高抗Pb29和CK节肢动物群落各营养层功能团组成类似，但高抗Pb29节肢动物群落中基位物种食叶害虫大量减少，中位物种所占比例增加，项位物种没有明显变化。

Every community was stable relatively. Interspecific association was the loosest and stability was the highest in Q. wutaiensis community. But the insignificant positive association among species showed that Q. wutaiensis community has not reached the stable state, so we still should protect the local natural vegetation reasonably for a long time.

演替系列各群落都具有相对的稳定性，演替顶极辽东栎群落的种间联结性最弱，稳定性最高，但多物种间不显著的正相关说明该地区分布最广、面积最大的辽东栎群落可能尚未达到稳定状态，仍需要对该地区天然植被进行长期保护。

The semi-variogram values of above-ground biomass of perennial herbs and Mesophytes, following the increase of spatial distances, showed decreasing trends when semi-variogram values exceeded the effective range.

群落中生态功能群旱生植物的波动变化不仅对群落盖度、草场的生产力有直接的影响，而且对草场群落及其生态系统的稳定和生态功能的发挥具有重要作用。

Daya Bay was shown to be ecologically disturbed and the stability of macrobenthic community was weak. Specifically, the inner bay and main area of the central bay was strongly disturbed and was dominated by Group Ⅰ community that was characterized as simple low stability and dominated by molluscs. Dominant species were Veremolpa micra and Timoclea scabra.

大亚湾海域生态环境受到明显的扰动，处于扰动状态中的大型底栖动物群落稳定性较差；湾顶和湾中大部分海域内的群落Ⅰ，为大亚湾的主体群落，以软体动物为主，种类组成单一、季节变化小，以小鳞帘蛤Veremolpa micra和粗帝汶蛤Timoclea scabra为特征种。

Based on the research on the evolution mechanism of information ecological communities,and by the use of the system development view and the related theories of complex systems,this paper redivides the evolution process into formative process,linear evolution process,non-linear evolution process and dissolution process according to the essential characteristics of information ecological communities.

本文在信息生态群落演化机理的研究基础上，运用系统发展观和复杂系统的相关理论，根据信息生态群落演化过程的本质特点，对演化过程进行了重新划分：信息生态群落的结体创生过程、线性常规演化过程、非线性超常规演化过程和分化解体过程。

The diversity indices of communities located between 1400 and 3600m of theTaibaishan,the highest peak of Qinling Mountain Range located in the southern edge ofthe WTZC,are studied based on data from 55 quadrats.

对秦岭主峰太白山海拔1400-3600m之间植被类型和物种多样性进行了研究，在划分的15种群落类型中，以位于海拔1500-2300m之间的落叶阔叶混交林和栎类混交林的群落多样性最高，在海拔2300-3600m之间，群落多样性趋于单调下降，反映了熟量的不足在这一海拔高度范围成为多样性的主要限制因子。

"Chaparral:a biome characterized by hot, dry summers and cool, moist winters and dominated by a dense growth of mostly small-leaved evergreen shrub s, as that found in the foothills of California."

沙巴拉群落：由主要为小叶常绿密生的灌木组成的生物群落，夏季干旱炎热，冬季凉爽湿润，如存在于加利福尼亚州山麓小丘的一个生物群落。
