Greater Brown Wren Warbler and yellow-bellied Wren Warbler (P.flavive-ntris) are the sympatric species pair in south China.In this paper,the interspecific niche relationship between the two bird species was studied.

本文研究了褐头鹪莺和黄腹鹪莺(P.flaviventris)在取食高度、取食基层和取食方法3个生态维度上的生态位宽度和生态位重叠以及它们与复合种群密度的关系。

This weed population had a wider niche breadth, the second widest among 12 major weed populations in weed community, and had bigger niche overlap with Stellaria alsine, Alopecurus acquallis, Malachium aquaticum, Poa annua, Polygonum persicaria and Lapsana apogonoides. In rape, wheat or fallow, B.

在杂草群落中，草的生态位宽度居第2位，说明其有潜在的较强的适应环境的能力；草与雀舌草、看麦娘、牛繁缕、早熟禾、春蓼和稻搓菜等杂草种群的生态位重叠较大，与它们的生态要求比较接近。

Secondly, ecological meaning of geotectonics is provided based on the rule of geotectonics being one of the energy source of eco-environment.

并对生态环境进行了较为严格的定义，即生态环境是以人类种群为主体的，以物质、能量和信息等有机联系维持人类生态系统正常运转的天然生态系统。

In the n-dimensional space, the fundamental niche is a hypervolume. The realized niche is described as the environmental characteristics that surround a species population in a particular community.

在n维生态位空间，物种的基础生态位为一实体，实现生态位则是在某一特定群落生境中一种群所处的环境参数所描述。

The population dominance index, Shannon-Wiener index, evenness, niche breadth and community similarity were used to analyze the diversity and eco-niche of soil moniliaceous hyphomycetes in five ecosystem-types.

A space series substituting time series method was adapted and Levins niche breadth index and the Pianka Niche overlap index was applied to calculate the resumption of different age and population niche and niche overlap in spring-autumn grassland enclosed for different years at Zhaosu horse ranch.

采用空间序列代替时间序列的方法，运用Levins生态位宽度指数和Pianka生态位重叠指数，对不同围封恢复年限种群生态位及生态位重叠计算分析。

In order to exploit efficiently the ornamental resource-Cerasus subhirtella var. ascendens, based on the importance value as one-dimension resource state, the niche characteristics of ten dominant tree populations in C. subhirtella var. ascendens community in Wuyi Mountain of Fujian Province were calculated and analyzed with Levins, Hurlbert, Pianka and Schoener formulas.

为了更好地开发利用野生早樱这一木本观花植物，以物种重要值为生态位计算资源状态指标，应用Levins公式、Hurtlbert公式、Pianka公式和Schoener公式对福建武夷山野生早樱群落乔木层10个优势种群进行生态位宽度、生态位重叠和生态位相似性比例的计算与分析。

The realized niche of SRB in the acidogenic-desulfate system is determined by its function; and the figure of three-dimension realized niche of its population is also presented, which is restricted by pH, ORP and ALK.

SRB种群的功能决定了它在产酸脱硫系统中的实现生态位，并给出了由pH值、氧化还原电位和碱度制约的SRB种群的三维实现生态位图。
