文档介绍：海水PH和浮游植物数量的关系
[摘要]:赤潮发生主要是浮游植物的大量繁殖。本实验于2004年3月~5月,以硅藻、金藻、绿藻为材料,对三种藻类进行40天的培养,,,,:硅藻: y(数量)=×105PH-×106,金藻:y(数量)=×105PH-×106,绿藻: y(数量)=×105PH-×: 硅藻: y(数量)=(天数),金藻: y(数量)=(天数),绿藻: y(数量)=(天数).

Abstract: Red Tide primarily arises from large quantities reproduction of experiments were made during March and May in 2004, regard diatoms, chrysophyta, chlorophyta as the material, proceed to three kinds of algae 40 days educates, recording the value of PH and numbers of phytoplankton once everyday. The result of experiment expresses,when the value of PH smaller than ,the relationship between PH and numbers of phytoplankton report to spread to order to distribute
.When algae large quantity breeds the value of PH larger than , the relationship between PH and numbers of phytoplankton exsit certain line form application covariance general outline learns the returning of inside returns the analysis can make the relation curve of three kinds of algae after returning: diatoms: Quantity=×105×PH-×106, chrysophyta: Quantity =×105×PH-×106, chlorophyta: Quantity=×105×PH-× their growth curve in addition: diatoms: Quantity = , chrysophyta: Quantity = days,chlorophyta: Quantity = days.
Key words: red tide; PH; numbers of phytoplankton
1前言:
赤潮的定义:赤潮就是在一定的环境条件下,海水中某些浮游植物、原生动物或细菌在短时间内突发性增殖或高度聚集而引起的一种生态异常,并造成危害的现象。
赤潮的历史:赤潮现象在古代文献如《旧约·出埃及记》中就曾提到过。在日本,早在藤原时代和镰仓时代就有赤潮方面的记载。1603年法载了美洲罗亚尔湾地区的印第安人根据月黑之夜观察海水发光现象来辨别贻贝是否可以食用。1831~1836年,达尔文在“贝格尔”,我国早在2000多年前就发现了赤潮现象,在一些古代文献或艺术品中也有一些有关赤潮方面的
