摘　　要：通过对小浪底库区主要监测断面的藻类数量进行调查,揭示藻类数量随时间的变化趋势,以期为库区水华防治提供技术支撑。结果表明,小浪底库区中央地带藻类在数量上符合其客观生长规律,库区边缘区域藻类生长受较多因素影响,其数量随时间呈现跳跃式变化,出库断面藻类数量的主要影响因素是温度和光照。To provide a technical support to the prevention and cure of water bloom, the paper have detected the number of the algae of the major monitoring area in Xiaolangdi reservoir and studied the major impact factors of the change in value of the algae and its change rule along with time. The results showed that the development of the number of the algae in the central area fits the objective laws, while in the marginal areas, due to external factors, its trends is jumping. The major impact factors of the number of the algae in Xiaolangdi reservoir downstream are temperature and light.
