查询词典 phytoplankton

Based on the data observed in four seasons during May 2004 to February 2005 and collected during the red tide occurrence period from 2001 to 2005 in the Nanji Islands sea area, the seasonal variations in species composition, dominant species and cell abundance of phytoplankton in the sea area, their relations to the environmental factors and the occurrence conditions of dinoflagellate red tide in spring are analyzed.

根据2004年5月－2005年2月4个季节的调查资料以及2001-2005年赤潮发生时收集的资料，分析了南麂列岛海域浮游植物的种类组成、优势种类、细胞丰度的季节变化及其与环境因子的关系、春季甲藻赤潮发生状况。

A total of 116 taxa (including 17 uncertain species) belonging to 56 genera of 5 phyla were identified. The main phytoplankton group was diatom and the second was dinoflagellate.

The phytoplankton diversity was restricted by environment factor such as water temperature, salinity, COD, biomass, species.

浮游植物多样性主要受水温、盐度、COD、生物量、物种数等环境因子的制约。

One popular idea is to use iron to fertilise the sea, causing the same explosions of phytoplankton that often precede dead zones and red tides.

有这么一个流行的想法：用铁作为肥料向海洋施肥。这样就能在死水区域和红潮的出现前引起浮游生物同等级的激增。

We argue that the changes in meroplankton abundance, coincident with increased phytoplankton and declining holoplankton, reflect the synchronous effect of rising SST and related changes in the pelagic community on the reproduction and recruitment of many benthic marine invertebrates.

我们推断季节性浮游生物丰度的变化与浮游植物的增长和终生浮游生物的减少是保持一致的，是海水表面温度上升的反映，并与许多远洋底栖无脊椎动物的生殖生长相关。

As one of the hydrophyte, phytoplankton has a broad application.

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。
