| 2007年4月～2008年3月,对河北省秦皇岛市青龙满族自治县境内青龙河上的桃林口水库中的4类主要浮游动物进行了调查,分析了该水库浮游动物多样性与生物量的周年变化规律,结果显示:2007年4月～2008年3月,在桃林口水库共观测到浮游动物57种,其中原生动物16种、轮虫22种、枝角类12种、桡足类7种,浮游动物的组成和优势种在不同的月份不同;浮游动物数量平均值为185.90个/L,在初秋最高,各个采样点平均峰值出现在8月(513.60个/L),春、夏随着温度的升高数量也逐渐增加,9月以后又开始下降,而在冬季含量最低;浮游动物生物量平均值为1.68mg/L,也是在初秋最高,各个采样点平均峰值出现在8月(7.26mg/L),春、夏随着温度的升高数量逐渐增加,9月以后又开始下降,而在冬季含量最低。 |
| 英文摘要: |
| Four primary zooplankton species in Taolinkou reservoir located at Qinglong fiver in Qinglong Manchu county in Hebei province were investigated from April 2007 to March 2008, and the zooplankton species and anniversary distribution were concluded. The results showed that in the investigating period 57 kinds of zooplankton were totally found with protozoa 16, rotifera 22, cladocera 12 and copepoda 7, the forms and the preponderant species were different in different months. The average quantity of zooplankton in each month was 185.90 ind./L. The maximum quantity appeared at the earlier autumn. The average quantity （513.60 ind./L） of all sampling stations raised to its peak in August. The quantity was increasing with the temperature in spring and summer, decreasing after September, and lowest in winter. The average biomass was 1.68 mg/L which was the same diversification as the average quantity. |
