| 摘 要： | 浮桥河水库浮游植物水柱日生产量变幅为0.34-4.99 g/(m2·d),最低值出现在下游冬季,最高值出现在中游秋季,年平均值2.75 g/(m2·d)季节变化:秋季＞夏季＞春季＞冬季,与浮游植物叶绿素a含量和生物量的季节变化一致;水平分布:中游略高于上游,下游最低,与浮游植物叶绿素a含量的水平分布完全一致表层日生产量占水柱日生产量53.81%.与1980年同期相比,浮游植物初级生产力增加了1.2倍.分析表明,磷含量增加是浮游植物初级生产力提高的关键因子.应用能量收支法估算浮桥河水库鲢鳙渔产潜力为772t,516.0 kh/hm2.从渔业管理和水质管理角度讨论了合理利用浮游植物初级生产力的措施. |

| Abstract: | The primary production of phytoplankton was investigated from April 1997 to January 1998 in Fuqiaohe Reservoir of Hubei Province.It ranged from 0.34 -4.99g/(m2·d), with the highest values in the middle reaches by horizontal distribution and in autumn by seasonal distribution, and with the smallest in the lower reaches and in winter.The annual average was 2.75g/(m2·d).The primary production of phytoplankton was higher in the middle reaches, followed by the upper, and lower reaches.As a result of phosphorus increase, the primary production of phytoplankton increased 1.2 times comparing with the result of the same period of 1980.The production potential of silver carp and bighead estimated was 77.2x104kg, or 516.0kg/ha.The techniques of reservoir fishery management and water quality management by making rational use of the primary production of phytoplankton were discussed. |
