| 摘要: |
| 于 1997年 4月至 1998年 9月对山东省高青赵店渔场 (37°17'N,117°55'E)的盐碱池塘叶绿素进行了调查研究.结果表明,盐碱池塘叶绿素总量平均为 115.12μg·L-1,叶绿素 a平均含量为 73.90μg·L-1,占叶绿素总量的 61.76%,叶绿素 b和叶绿素 c分别占总量的 12.97%和2 5.2 7%.叶绿素 a含量的季节变动较大,有明显盛夏和初秋高峰期.无鱼对照池的叶绿素 a比养鱼池塘低得多.叶绿素 a的昼夜变化与垂直分布变化较大,但不遵循同一模式.盐碱池塘叶绿素 a含量与浮游植物生物量、水温、总氮、总磷和硅酸盐显著正相关,与透明度显著负相关,而与盐度、碱度、p H、硬度、电导率均无规律性联系. |

| Abstract: |
| The chlorophyll of phytoplankton in saline-alkaline ponds in Zhaodi an Fish Farm (Latitude 37°17'N,Longitude 117°55'E), Gaoqing County, Shandong Province, during April 1997 to September 1998, was measured.319 samples were collected.The results indicated that the mean concentration of chlorophyll in experimental ponds were 115.12μ g° L-1, mean concentration of chlorophyll-a were 79.90(μ g° L-1.The percentage of the content of Chla, Chlb and Chlc to total concentration of chlorophyll was 61.76%, 12.97% and 25.2%, respectively.The concentrations of Chla had obvious seasonal dynamics, and have a peak value in summer and early autumn.The concentratio nof Chla in control ponds was much smaller than that fish-culture ponds.The temporary and spatial changes of Chla were greater, but the pattern of dynamics is not unit.The concentration of Chla in experimental ponds have significant positive correlation to the biomass of phy to plankton, water temperature, total nitrogen, total phosphorus and silicon, and negative correlation to water transparency.No regular correlation of Chla concentration to salinity, alkalinity, pH, hardness and conductivity is found. |
