| 3. | By shannon index evaluation , 29 . 25 % of genetic variation was between populations and the differentiation among populations was at a high level , in comparison with other species , such as s . grandis
Shannon指数估测有29 . 25的遗传变异存在于种群间，种群间的遗传分化较高。 |
| 4. | Richness index , evenness index and diversity index were selected as indicators of pedodiversity . here we used shannon index ( h " ) as diversity index and pielou index ( e ) as evenness index
土壤多样性指数包括丰富度指数（特定区域内发育的土类数目） 、多样性指数（ h ）和均匀度指数( e ) 。 |
| 5. | A total of 145 rapd loci were obtained , of which 132 loci ( 91 . 03 % ) were polymorphic . genetic diversity quantified by shannon index varied from 1 . 50 to 2 . 44 with an average of 1 . 93 ; partition of genetic variability indicated that 69 % was distributed within , and 31 % among stocks
从40个1obp引物中选取20个用于群体遗传多样性分析，共检测出145个位点，其中132个( 91 . 03 % )显多态性;用shannon多样性指数量化的平均遗传多态度为1 |
| 6. | Total genetic diversity by shannon index was 0 . 5240 , mean genetic diversity within subpopulation was 0 . 4437 , genetic diversity within subpopulation accounted for 84 . 67 % of ' total genetic diversity , and that among subpopulations accounts for 15 . 33 % , that is 85 % of genetic variation within subpopulation , and 15 % among subpopulations
为了从更大尺度和更深层次上理解生态过渡性与遗传变异过渡性的联系，我们对该过渡带的梭梭、碱蓬和叉毛蓬三种植物的遗传变异进行了rapd分析。结果显d 。 ， 。 |
| 7. | Primers of ecori were signed with fluorescent dye and four pairs of primers were selected from twenty - four pairs . 261 dna fragments were generated by the four pairs of primers in forty - three individuals sampled . percentage of polymorphic bands is 51 % , the value of shannon index ( i ) is 0 . 086 and nei ' s gene diversity ( h ) is 0 . 151
统计这些aflp表型带标记，用popgene软件计算各种多样性数据( ppb值为51 ， shannon多样性指数为0 . 086 ， nei ' s基因多样性值为0 . 151 ) ：用ntsys软件计算各个样品间的相似性系数，并用upgma法基于相似性系数进行聚类分析，构建树状图，它们可反映出元宝山冷杉种群内个体间的遗传关系。 |
| 8. | Shannon indices suggested that the differetiation of the fenneropenaeus chinensis was divided into two parts , 24 . 0 % from inter - populations and 76 . 0 % from intra - populations . the hierarchy analysis of the population answered for shannon indices , t hat is , 78 . 81 % of the variance was from intra - populations
Shannon多样性指数表明中国对虾群体的遗传变异有76 . 0来自种群内， 24 . 0的变异来自群体间， nei多样性指数表明中国对虾群体的遗传多样性有78 . 10存在于群体内。 |
| 9. | At the same time , the result of the functional diversity of soil microbial community indicated that soil microbial metabolism quotient ( awcd ) , microbial community richness and shannon index all decreased significantly in red soils polluted by cadmium and lead compared with non - polluted soils . these results suggested the structure of microbial community have changed , decreased the functional diversity of microbial community , and reduced the microbial number utilizing different carbon resources
Biologgn测试结果显示，镉、铅污染红壤微生物群落代谢剖面( awcd )及群落丰富度、多样性指数均显著低于非污染土壤，表明重金属污染引起了土壤微生物群落功能多样性下降，减少了能利用有关碳源底物的微生物数量、降低了微生中义摘要物对单一碳源底物的利用能力，最终导致土壤微生物群落功能多样性发生变化。 |
