| 摘要: |
| 于1986年3月 - 1990年9月，对中国北方一些盐田和盐湖的高盐水域（盐度61.0－320.0）中的藻类（主要是浮游藻）进行调查。在青岛东风盐场和天津汉沽盐场每月2次定点采集藻类标本水样72份以及随机在山西解池、青海尕海、新疆达板城盐湖和巴里坤湖采集水样5份。鉴定出蓝藻5种，绿藻8种，硅藻8种。结果表明，均是典型的耐盐或喜盐种类，但其种的多样与水体的盐度呈负相关。藻类种群生物量以春季和秋季最为丰富，夏季次之，冬季最少。夏季的数量变动除了与水温有关外，可能还与卤虫、轮虫、原生动物等动物的摄食有关。 |

| Abstract: |
| From March, 1986 to September, 1990, samples of mainly planktonic algae were collected from 3 salt pans and 4 saline lakes (salinity 61.0 - 320.0) in northern China. Among all the samples, 72 water samples were collected twice per month from the Dongfeng saltern in Qingdao and from the Hangu saltern in Tianjin and 5 water samples of saline lakes were collected randomly from Xie Chi in Shanxi Province, Ga Hai in Qinghai Province, Dabancheng saline lake and Barkol Lake in the Xinjiang Autonomous Region. Of the 21 species identified, 5 species were blue-green algae, 8 species green algae and 8 species diatoms. Although these algae were halotolerant or halophilic species, in general, the species diversity was inversely related to the salinity of the salt pans or lakes. The observed biomass of algae was large in Spring and Autumn, Summer, small in Winter, in-between in Summer. The variety of algal biomass in summer was possibly related, to grazers such as brine shrimps, rotifers and protozoans. The ecological significance of algae in high salin it waters and exploitation of algal resouces are discussed in this paper. |
