metapopulation造句
例句与造句
- Theoretical basis for species conservation : from the theory of islandbiogeography to metapopulation dynamic theory
从岛屿生物地理学理论到集合种群理论 - The population structure is typical metapopulation ( source - sink population ) with nine patches . the patch of west gully and shanwang - temple gully is the source population and the population in these patches is a dynamic process from extinction to reclonizition
种群结构为典型的异质种群，且为源-汇种群，共有九个斑块，山王庙、西沟斑块为最大的源种群斑块。 - Most if not all species live in patchy habitats . this has become increasingly true because of landscape fragmentation throughout the world . the set of local ( patch ) populations of a species in spatially discrete habitats may be called a metapopulation
随着全世界范围内景观破碎化的加剧，大多数物种都逐渐生活在斑块状生境中，这成为一个不争的事实，分布于不连续生境中某物种的一系列斑块(局部种群)就称之为复合种群。 - The temporal and spatial dynamics of a single species metapopulation is modelled by a model . the stability of spatial distribution of the population and relationships between the stable patchy distribution and migration rates and finite rate of growth of subpopulations are also investigated . finally measures to boost the growth of total population are presented through the model and analysis of the model
通过模型模拟了呈一般缀块分布的单种种群的时空动态.讨论了种群空间分布的稳定性及稳定缀块分布与种群在缀块间迁移率和子种群增长率之间的关系，并由此提出了促进全局种群增长的措施 - At present , there have been extensive studies on the animal metapopulation . however , studies on the plant metapopulation are rare . in addition , studies on metapopulation in our country mostly focused on translating extemal papers and introducing the situation of their researches , and nearly there is n ' t material study on metapopulation
另外国内虽已开始重视复合种群的研究，但目前的工作还主要集中在对文献资料的翻译和对国外研究进展的介绍方面，涉及对复合种群的有关理论探索和经验研究方面仍然近于空白。 - It's difficult to find metapopulation in a sentence. 用metapopulation造句挺难的
- And through leslie matrix analysis , we deduced , except of the subpopulation at altitude 490m , the subpopulations of lilium tsingtauense will not die out if not been disturbed badly . we estimated the growth ability and resistance ability of both metapopulation and local population by use the method of quamitative analysis for population structura1 dynamics . the growth ability order is population l > population 2 > population 3 > population 5 > population 6 > metapopulation > population 4
川叩iqu n了e ）复合种群研究摘要从种群年龄结构的稳定、衰退、增长概念出发，以种群结构参数为依据，运用加权法与条件概率乘法法则，定量椎导出衡量种群年龄结构及群落结构的动态指数，该方法克服了过去在植物种群结构动态比较评价中粗放的等级归类划分的缺陷，并能解决结构动态定量比较评价问题，因而认为有普遍使用的价值。
