为了解城市绿地景观水体综合治理技术的应用效果，对天山公园水体浮游植物群落进行了调查。结果表明：调查期间共鉴定出浮游植物299种，隶属于8门，浮游植物密度范围为107．4×105～377．2×105 ind· L‐1，群落组成以蓝藻、硅藻、绿藻为主。主要优势种有尖尾蓝隐藻、小球藻、方胞螺旋藻、细微颤藻、最小胶球藻等。通过减少外源污染、水质强化处理、构建水生生态系统，对水质改善有明显作用。%In order to understand the method of landscape water treatment ,a field survey on phytoplankton com‐munity was conducted in Tianshan Parks from July to October in 2010 .A total of 299 species were identified , belonging to 8 phyla .The phytoplankton density ranged from 107 .4 × 105 ~377 .2 × 105 ind·L‐1 .The phyto‐plankton community was mainly composed of Cyanophyceae ,Bacillariophyceae and Chlorophyceae ,the domi‐nant species were Chroomonas acuta ,Chlorella vulfaris ,Spirulina jenner ,Oscillatoria subtillissima and Gloeo‐capsa minima .Reducing the external pollution ,strengthening water quality and the construction of aquatic eco‐system had obviously effect on the improvement of water quality .
