群落

In the broad-leaved Korean pine climax forest, the fine root climax production of the community occurs in July and October, but the dominant arboreal species, understory arboreal species and fine roots of grass have a different production dynamics. It is important to sort the fine root species because accurate fine root production sources have a different fine root dynamics.

在原始阔叶红松林中，群落细根的生长高峰发生在7月和10月，但其中主要树种、其他木本和草本的细根有着不同的生长动态，所以在计算细根生产量时应该分类计算，才会得出较为准确的结果。

The process of natural succession of restoring vegetation in central Guizhou after rocky desertification in Karst area was divided into the herbosa stage, the stage of herbosa-shrub, the stage of vine-shrub, the stage of subaltern tree forest and the climax stage.

黔中喀斯特地区石漠化后，植被恢复自然演替过程可分为草丛阶段、草灌阶段、藤刺灌丛阶段、次生乔林阶段和顶级群落阶段。

Match the biome in the figure below with the appropriate plotted area in the climograph.

point请将下图中的生物群落区和气象图中小区块(a， b， c， d， e，和f)相配对1分

According to the results of sequencing, lactic acid bacteria and Clostridium sp.

UPGMA聚类分析和PCA分析结果也表明，pH=7和pH=8时的微生物群落结构相似，pH=5与之显著不同。

The results show that the different dominant populations of the community and the distributive patterns of Heptacodium miconioides community in different quadrats are clumpy distributed, but they are different in terms of intensity.

结果是：群落中各优势种群均呈集群分布；七子花种群在各样地亦呈集群分布，但集群强度有差异；各样地中七子花种群小树的集群强度均大于中树，种群呈扩散趋势。

On the early days of planting vegetation,we advise that the sanitary landfills introduce green bristlegrass,fat hen and cockspur grass at the same time of sodding.On the latter days,they can plant some good shrubberies to hold the soil of the slope.

建议在卫生填埋场植被建设初期，在种植人工草皮的同时，适当地引入狗尾草、稗草、灰菜等野生优势种，使野生草本群落逐渐替代人工草坪；在植被建设中后期，种植适量抗性强的优良灌木树种，以提高填埋场植被的物种多样性，增加坡面景观效果，发挥植被护坡固土的生态功能。

Using the Pearson correlation coefficient and Spearman rank correlation coefficient, the interspecific association of 13 species in different communities in Beijing mountainous area were investigated, and the niche breadth and niche overlap of 13 species were studied.

应用Pearson相关系数和Spearman秩相关系数检验，研究了北京山区天然林群落13个乔木种群的种间关联性，并对13种植物种群的生态位宽度和生态位重叠进行研究。

The characteristics of protozoan community structures and their colonization were analyzed.

分析了该原生动物群落的结构和群集过程的特征，结合水质的理化参数对该处理系统效能进行评价。

But researchers say they do not know this virus causes a colony to collapse.

但是研究者说，他们不知道这种病毒会导致群落的崩溃。
