摘　　要：基于潘家口水库水环境状况,描述了2009～2011年潘家口水库优势藻种及其密度演变过程,概括了藻类对水温、营养盐等水环境因子的响应机制;并由2010年10月～2011年8月多断面水质监测数据,分析了潘家口水库优势藻种与水环境因素的适应性。结果表明,各断面优势藻种有向单一种群演化的趋势,水体富营养状况逐渐恶化;识别出潘家口水库富营养化控制的关键区域和重点防范对象,并结合潘家口水库的运行条件提出富营养化防治的建议。The author descmbed the dominant algal species and the revolutionary processes oi their densities in Panjia- kou Reservoir based on the water environmental situation during the period of 2009 to 2011. The response mechanisms of algae on the water environmental factors, such as temperature and nutrients, were summarized. According to the monito- ring data of multi-section water quality in Panjiakou Reservoir from Oct. 2010 to Aug. 2011, the adaptabilities of dominant species to water environmental factors were analyzed. The results show that the dominant algal species of each section tended to revolute to a single population and that the water eutrophication condition gradually deteriorated. However, the key areas and preventive objects in controlling water eutrophication were identified, and recommendations under the cur- rent Panjiakou reservoir operational conditions were given.
