species evenness meaning in Chinese
种均匀度
Examples
- The results showed that : from north - facing slope to south - facing slope and plain field , the species evenness and diversity index decreased ; from plain field to north - facing slope and south - facing slope , richness index also decreased
结果表明，当生境由阴坡向滩地到向阳坡变化时，各种多样性指数的变化顺序为，物种丰富度：滩地阴坡阳坡；均匀度和多样性指数：阴坡阳坡滩地。 - E . due to favorable condition of soil moisture , weak activity of wind and sand , and low inter - specific competition intensity resulting from repeated alternation between sand dunes and inter - dunes , the plant species richness and the plant species evenness are quite high in inter - dunes . f
由于丘间地水分条件较好，受风沙活动的影响较小，同时由于流动沙丘和丘间地的不断更替降低了物种之间的竞争强度，就使丘间地具有较高的物种丰富度和物种均匀度。 - Gradually , with the more and more transpiration of the vegetation , and with the reduction of the deep soil moisture , in the end , a kind of balance of soil moisture will appeared and be kept for ever between the precipitation and the transpiration of vegetation , and the manual sand - fixing vegetation will be transformed consequently into its natural climax stage completely , in which the dominant plant is leymus secalimus , and in which the plant species richness is not too low , but the plant species evenness is the lowest
设置机械沙障和生物沙障的初期，植物的物种丰富度、物种均匀度会有一个暂时的提高；但是在人工固沙植被的发育盛期，物种丰富度会降低；随植物群落蒸腾耗水量的不断增大，人工植被不断地衰退，最后发展到赖草土壤顶极群落，此时的物种丰富度并不低，但是物种均匀度很低。 - The following contents were mainly studied : ( 1 ) aspect , structure as well as characteristic of species composition between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest ; ( 2 ) species diversity , species abundance and species evenness between fragmental evergreen broadleaved forests and contin . . us evergreen broadleaved forest ; ( 3 ) plant floristic compositions at family and genus levels between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest ; ( 4 ) life form between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest ; ( 5 ) microclimate factor ( sun radiation , temperature , wind velocity , humidity ) in different level pattern ( open , edge and interior ) between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest ; ( 6 ) the relations between environment and soil factors as well as species diversity of forest community between fragmental evergreen broadleaved forests and continuous evergreen broadleaved forest
主要研究以下内容： ( 1 )片断和连续常绿阔叶林的外貌、结构和物种组成特征； ( 2 )片断和连续常绿阔叶林的物种多样性、丰富度和均匀性； ( 3 )片断和连续常绿阔叶林的科( ? )属水平的植物区系成分； ( 4 )片断和连续常绿阔叶林生活型组成； ( 5 )在不同的水平梯度格局上(林外、林缘和林内) ，片断和连续常绿阔叶林的小气候要素(光照、温度、风速、湿度等) ； ( 6 )片断和连续常绿阔叶林的环境和土壤因子，与群落的物种多样性之间的关系。实验结果表明： ( 1 )各片断森林的外貌特点基本上和连续森林一致。 - The result suggests that the species richness index ranks as following among 6 stations : yangma islet > drogan - whisker islet > moon bay > jingouzhai > jingouzhai gravel , and yangma islet possessed the highest species diversity index , while jingouzhai the lowest , the order of species diversity index among 6 stations is yangma islet > moon bay > drogan - whisker islet > jingouzhai > zhifu islet > jingouzhai gravel , the order of species evenness index is : moon bay > drogan - whisker islet > yangma islet > jingouzhai > zhifu islet > jingouzhai gravel
红藻群落的物种丰富度依次为：养马岛芝罘岛龙须岛月亮湾金沟寨金沟寨砾石滩；物种多样性指数以养马岛为最高，金沟寨砾石滩最低，依次为：养马岛月亮湾龙须岛金沟寨芝罘岛全沟寨砾石滩；物种分布的均匀度指数依次为：月亮湾龙须岛养马岛金沟寨芝罘岛金沟寨砾石滩。
