Finally, the research of Medicago falcata distribution strategy, inter-community diversity and its mechanism of variation was conducted through abundance index, diversity index, equality and inequality study in different communities.

最后，通过沿坡度梯度分布的不同群落类型的丰富度指数、物种多样性指数、均匀度和非均匀性的研究，探讨了内蒙古黄花苜蓿的分布规律、群落内物种多样性及其变化机制。

On the other side, the relations among community classification, structure, diversity and distribution pattern were also investigated through the study of species composition, diversity and interspecific relation of Medicago falcata in Inner Mongolia.

另一方面，本文又以松嫩平原天然草地中的五脉山黎豆、多茎野豌豆、花苜蓿以及内蒙古的黄花苜蓿为研究对象，从植物群落的物种组成、多样性、种间关联等几方面探讨了我国天然草地中豆科牧草的群落类型、结构、群落多样性与分布格局之间的关系。

Structure index was significantly (P.05) different among three plant species whereas channel index and enrichment index were not. Plant species not only modified abundance of plant-feeding, omnivorous and predatory nematodes, but also percentage of each trophic group. Bacterivorous and fungivorous nematodes were affected most by the differences in plant species.

研究表明在沙地生态系统中，3种植物根际土壤线虫群落的多样性、丰富度、均匀度和线虫总数虽然都存在一定的差异，但不显著；功能多样性指数中结构指数存在显著差异，而通道指数、富集指数不存在显著差异；3种植物对根际土壤线虫群落中各营养类群线虫的比例有显著影响。

The haplotype diversity and the nucleotide diversity of total samples were 0.851±0.028 and 0.01356±0.0008, respectively.

总样品的单元型多样性和核苷酸多样性分别为0.851±0.028和0.01356±0.0008。

The haplotype diversity index of Yangtze River population and Pearl River population was 0.5263 and 0.6104, respectively.

长江群体和珠江群体的单倍型多样性指数分别为0.5263和0.6104，核苷酸多样性指数分别为0.144%和0.192%。

The journal dedicates to the studies of the taxonomy, phylogeny and evolution of botany. Research areas mainly include plant diversity conservation, molecular phylogenetics, population biology, morphology, biodiversity, herbaria and nomenclature etc.

该刊致力于植物学的分类学、系统发生和进化方面的研究，研究领域主要涉及植物多样性的保存、分子系统发生学、种群生物学、形态学、生物多样性、干燥标本集以及命名法等等。

Comparing the genetic diversity of Coreius heterodon with that of other fishes, the experiment revealed that the genetic diversity of Coreius heterodon in the lower reach of the Yangtze River was a little lower.

通过与其他鱼类的遗传多样性的研究结果比较可初步判断，长江下游铜鱼群体的遗传多样性较低。

There was great diversity index among genetic trait of 50 barley. The anomic trait used as tested materials was analyzed by cluster. Cluster analysis showed that 50 barley could be classified into 5 groups at the level of GD 3.28; The 50 barleys were analyzed by A-PAGE to study genetic diversity of hordein.

各农艺性状的遗传多样性指数都较大，具有丰富的遗传多样性；对供试材料的农艺性状进行聚类分析，50份大麦材料在遗传距离3.28时可被聚为5大类。
