| 1. | Simpson shannon - wiener methods for measuring niche breadth and wang - gang niche overlap formula are more fitted to ecotone
Simpson 、 shannon - wiener生态位宽度公式和王刚生态位重叠公式对该区更为适用。 |
| 2. | The niche proportional similarity and the niche overlap index reflect the niche characteristics of the evergreen broadleaf trees in subtropical forest
结果表明:组成米槠林群落的优势种群绝大多数为广生态位,种群之间关系复杂,对资源具有一定的共享性。 |
| 3. | It demonstrated that there is strong competition between two for nature resource . the value of the niche overlap with cyrtomiian fortunei is secondly bigger , it is 0 . 3389
4 )荷叶铁线蕨与鸢尾的生态位重叠最大，为0 . 3515 ，表明两者间存在强烈的对自然资源的竞争。 |
| 4. | The paper holds that the degree of competition between enterprises is proportional to their niche overlap in an enterprise ecosystem where the environmental resources are limited
在一个环境资源有限的企业生态系统中，企业之间的竞争程度与其生态位重叠的程度成比例关系。 |
| 5. | Whereas , for the natural forest consisted of native species , the niche overlap was low and the interspecies relationship was harmonious . the composition structure of community thereby was more stable
而由本地树种组成的天然林，生态位重叠小，种间关系协调，群落组成结构的稳定性更高。 |
| 6. | There are five natural sample zones of adiantum reniforme l . var . sinense y . x . lin investigated , and recorded 34 species . 10 dominant species were used to calculate the niche width of populations and the niche overlap interpopulations
调查了5个自然样地，记录了34个伴生种，取10个优势种进行种群生态位宽度与生态位重叠的计算。 |
| 7. | In this study , the niche characteristics of 12 main tree populations in ? castanopsis carlessii ? forest have been analyzed by quantitative method at the nature reserve of wuyi mountains , including niche breadth , niche proportional similarity and niche overlap
植物种群之间的生态位相似性比例和生态位重叠指数指标值反映了亚热带常绿阔叶林的生态特征。 |
| 8. | In this paper , the niche characteristics of the dominant herb species in the subtropical ev - ergreen broad leaved woodland ( 53 species ) have been measured at the natural reserve of wanmu ling , including niche breadth , niche proportional similarity and niche overlap
对万木林自然保护区常绿阔叶林森林群落的53个主要种群进行生态位测定，包括生态位宽度、生态位相似比例、生态位重叠。 |
| 9. | Iii ) for artificial communities including herbaceous community , pure conifer and needle broad - leaved mixed forest , the poor niche configuration and serious niche overlap of component species made the composition structure of community be in an unstable state
3 )人工构建的群落(包括草本群落、针叶纯林和针阔混交林)其组成物种生态位配置差，生态位重叠大，造成群落组成结构不稳定。 |
| 10. | The results indicated that the greater the niche breadth of a species was , the stronger the ability of adaptation to environment and using resources was . the greater the niche overlap value for some species - pairs , the more similar the environmental requirements and resource use . the species with wide niche breadth may have high overlap value with species with narrow niche breadth , and low on the contrary
结果表明，种群生态位宽度越大，对环境的适应能力越强，对资源的利用能力也越强；生态位重叠越大，种群间的生态相似性越大，利用资源的相似性程度越高；生态位宽的种群对生态位窄的种群可能有较高的重叠值，反之则较低；生态位宽度最大的种群不一定为群落的建群种。 |
