| 摘 要： | 对天津某大型居住区内的一处景观水体进行了长期水质监测,结果表明:水体总磷(TP)、总氮(TN)含量分别为0.06~0.26 mg/L、0.69~2.6 mg/L;综合富营养化指数(TLI)为45~65,该景观水体属于中-富营养化水平;浮游植物群落主要由蓝藻、绿藻及硅藻组成。对位于下风向湖滨区水面漂浮絮体分析发现,该絮体主要成分为浮游植物,其活体成分以硅藻为主,藻密度达1.49×109个/L,显著富集氮(189.83 mg/L)、磷(27.4 mg/L)。若对该富集絮体进行定期打捞,可有效降低水体内源营养物质含量,有利于景观水体水质保持。

| Abstract: | Long term monitoring of water quality was carried out in a landscape waterbody located in a large residential district in Tianjin.The results showed that the concentrations of TN and TP were 0.69 ～ 2.6 mg/L and 0.06 ～ 0.26 mg/L,respectively.The TLI was 45 ～ 65,which indicated that the water quality was refered to the middle-eutrophic level.The main algal communities were blue-green algae and diatom algae.The flocs floating at downstream of the lakeside area were collected.The microscopical analysis showed that the main components were phytoplankton,most of which were diatom algae with cell density of 1.49 × 109 cell/L.This flocs was enriched significantly with nitrogen (189.83 mg/L) and phosphorus (27.4 mg/L).The study suggested that collecting the flocs in time from the waterbody can effectively reduce the nutrient concentration,which was beneficial to water quality protecting. |
