The seasonal variations of Chlorophyll-a was examined in relation to phytoplankton density and physico-chemical factors in Demirdöven Dam Reservoir during 2000-2001. Chlorophyll-a concentrations ranged from 0.62 to 7.19 mg/m3 and from 0.67 to 8.88 mg/m3 in 2000 and 2001, respectively. Maximum Chlorophyll-a concentrations were found near the metalimnion and decreased with depth. Chlorophyll-a concentrations showed positive correlation to phytoplankton density, water temperature and nutrient concentrations, and negative correlations to Secchi depth. Demirdöven Dam Reservoir can be classified as a mesotrophic reservoir according to Chlorophyll-a concentrations.
2000年至2001年期间，对德米尔多文大坝水库中叶绿素a的季节变化与浮游植物密度及理化因子的关系进行了研究。2000年和2001年叶绿素a浓度分别在0.62至7.19毫克/立方米和0.67至8.88毫克/立方米之间。叶绿素a浓度最大值出现在温跃层附近，并随深度降低。叶绿素a浓度与浮游植物密度、水温及营养物浓度呈正相关，与透明度呈负相关。根据叶绿素a浓度，德米尔多文大坝水库可被归类为中营养型水库。
