摘　　要： 自2011年11月到2012年10月,对广州大学城内A湖和B湖两个中小型景观湖泊进行了水质和藻类数量监测.用评分法对A湖和B湖进行评价,结果均为富营养级别,在监测期间有水质持续恶化和营养本底呈逐渐积累趋势.湖体水质富营养化趋势和水质波动与湖体构型、岸线等生态学特征密切相关,A、B两湖的岸线发育系数为1.91和1.38,易营养富集.A、B两湖藻类数量基本稳定在105数量级,变化规律相似,在3~7月藻增殖较快,7月到达年度峰值,主要受气候,湖泊功能规划和常量、微量营养物本底值及其比例的影响. The water quality and algae quantity of Lakes A and B in HEMC were monitored during Nov2011 to Oct 2012. Assessed by the method of marking,Lakes A and B were at the level of heavy eutrophication,the water quality tended to exacerbate,and the nutrients accumulated gradually during the research period. The water quality and its fluctuation were related with the surface shape and surrounding environment and lakeshore of the lakes. The shoreline index developments of Lakes A and B were 1. 91 and 1. 38,so it was easy for them to be rich in eutrophication. The variations of algae quantity in one year were similar in both lakes,remaining steady at 105,algae were in rapid proliferation from March to July,and their quantity reached an annual peak in July,which was influenced by the climate,lake functional planning,and the concentration and proportion of constant and trace nutrients.
