查询词典 Shannon

The H value was calculated to be 0.246 using Shannon-Wiener diversity index method.By aquatic reservoir evaluation criteria, combined with the type and density of zooplankton,it could be clearly determined that the water quality was seriously polluted and eutrophic.4.Comprehensive assessment of water quality:Affected by the influxion of sewage, slow flow velocity,high contents of nitrogen and phosphorus,the quantities of both zooplankton and phytoplankton at 1st point were relatively high,with the appearance of various indicator species of water pollution.

计算Shannon-Wiener多样性指数法得出H值为0.246，通过水库水生生物评价标准，结合浮游动物种类和密度，可以很清楚判定水质为污染严重，已经呈富营养化。4水质综合评价：排污口1号采样点受生活污水的大量排入的影响，且水流流速缓慢，水中氮磷含量高，因而浮游动物和浮游藻类数量都很高，而且出现很多污染生物指示种，综合分析该水层水质属污染严重的富营养化。

Shannon index showed biggest variations of populations was mignonette leaf on wulimu grass .

从shannon指数来看，群体变异程度最大的是五里木灰绿色羊草。

Using the Shannon-Wiener's niche breadth index and the Pianka's niche overlaps index, we found that the Nereis japonica, nemerteans and eelworms had broad niche breadths (above 2.80); the niche overlaps among them was high (above 0.90) in the quantitative analysis on the 21 species present in the quantitative sample analysis.

对定量取样中获得的21个物种以Shannon-Wiener指数为基础进行了生态位宽度测定，以Pianka重叠指数为基础进行了生态位重叠值分析，结果表明日本沙蚕、纽虫和线虫的生态位较宽，均为2.80以上，它们之间的生态重叠值也较高，均为0.90以上。

At last,we extend the Shannon-McMillan theorem to the nonhomogeneous Markov chain fields.

最后我们将Shannon-McMillan定理推广到非齐次马氏链场的情形。

Podocarpus nagi are the least.(5) Comparing the plant communities from different latitudes, it shows that the rule of community species diversity and community tree layer diversity index change as the latitude changes according with Wlater and Whittakers conclusion about Shannon-Wiener index decrease as latitude increase.

5与不同纬度的植物群落的比较结果表明：群落物种多样性和群落乔木层多样性指数随纬度的变化规律符合Wlater和Whittaker关于Shannon－Wiener指数随着纬度的升高而降低的结论，即与群落物种多样性的纬度趋势一致。
