Which is, does it make us better citizens of the biotic community? 也就是,它能使我们在这个生物群体中变的更好吗?
The Sense of the Biotic Community Encoded in Willa Cather's Works 薇拉·凯瑟作品中的生物共同体意识
Control impact of rice-duck ecological structure on harmful biotic community of rice fields 稻鸭生态结构对稻田有害生物群落的控制作用
Analysis on Impacts of Soil Micro-biotic Community by Transgenic Crops and Engineered Microorganisms 转基因作物和工程菌对土壤微生物群落影响的浅析
Based on the concept of biotic community in Biology, a 3-layer model named community-population-individual was proposed. Meanwhile, a parallel genetic algorithm based on learning mechanism ( PGABL) was developed on this model. 基于生物学群落的概念,提出了一个群落种群个体的三层模型,并在该模型上发展了一种基于学习机制的并行遗传算法(PGABL)。
The biotic extinction events in late Permian, which have been an important issue in the geologic community for the past decades, are the most severe and sweeping events in the history of biotic evolution. 二叠纪晚期爆发的生物灭绝事件是生物演化史上规模最大、影响最深远的事件,一直以来都是地学界的重大研究课题。
Diversity of river fOrm is the core of ecological environment of river basin ecosystem, and base for the diversity of biotic community. 河流形态多样性是流域生态系统生态环境的核心,是生物群落多样性的基础。
Under stable operation conditions, biotic community with relatively stable microorganism biomass and microbial activity was gradually developed in wetland substrate. 在湿地运行条件相对稳定的情况下,湿地基质中会逐渐形成数量和活性比较稳定的生物群落。
It insists on taking the stability of the whole "biotic community" as theoretical goal, taking ecological values as theoretical basis, taking moralism as theoretical foundation. 它主张以“生物共同体”的整体稳定为其理论目的,以生态价值为其理论基础,以道义论为其理论根据。
The mechanisms include: responses of ontogenetic physiological, behavioral, and genetic processes to the abiotic and biotic environmental variables and variability, and the overall consequences of these responses from individual organisms on the population, community and habitat that they belong to; 这些机制包括:个体发育、生理、行为和遗传过程对生物与非生物环境的反应及这些过程对自身所在的种群、群落和栖息地的影响;
Measurement of biotic community diversity VI: the statistical aspects of diversity measures 生物群落多样性的测度方法VI:与多样性测度有关的统计问题
The decisivenfactors of aggregation are stability of animal quantity, diversity of biotic community, complexity of landscape and sickly foci. 其聚集性是由宿主数量的稳定性、生物群落的多样性、景观的复杂性及疫点的多发性所决定。
This shows a kind of possibility that the standing crop of phytoplankton can be decreased by changing biotic community structure. this way avoids the danger of eutrophication, and reaches the aim of improving the quality of water. 这提供了一种可能:可以通过改变水体生物群落结构来减少浮游植物的现存生物量(standingcrop),从而避免富营养化的危害,达到改善水质的目的。
Consistency of biotic community and eco logicaI environment is a basic element of ecosystem. 生物群落与生态环境的统一性是生态系统的基本特征。
The enterprise cluster, which possesses some behavioral traits of the biotic community, is a social ecological system. 企业集群有着生物群落的行为特征,它本身就是一个社会生态系统。
Artificial reef has the impacts on adjoining environment and biotic community. 人工鱼礁对邻近理化环境、生物环境产生影响。
Soil microbial communities often reflect the biotic and abiotic properties of ecosystems such as plant community composition and plant traits, and thus any shifts in plant composition may lead to the changes in soil microbial communities. 土壤微生物群落的结构常常反映其所处生态系统的特点,如植被类型,所以植被类型的变化可能引起微生物群落结构和多样性的变化。
