中文摘要:
      通过2011年8月至2012年8月对长兴岛青草沙水源地实证基地样板池浮游植物进行11次调查采样,从种类数、细胞丰度、优势种、生物多样性指数等对样板池立体复合生态操纵修复前后浮游植物群落结构特征进行研究,并进行水质评价。结果表明:水体修复前,蓝藻占绝对优势;平裂藻、微囊藻和单角盘星藻为水体中的优势种;水体富营养化严重。经过“食藻虫—沉水植物—鱼类”立体复合生态修复后,浮游植物生物多样性增加,蓝藻得到有效的控制,微囊藻不再是水体中的优势种类,群落结构优化,水质明显改善,生态修复效果显著。
英文摘要:
      Phytoplankton of test pool of experimsental base in Qingcaosha water source, Changxing Island, was respectively investigated from August 2011 to August 2012. Types, cell abundance, dominant species, and diversity index of Phytoplankton community structure were compared and water quality was also evaluated around ecological multi restoration of the experimental base. The result shows that: before ecological restoration, the Cyanobacteria were absolutely dominant groups; Merismopedia sp., Microcystis sp., and Pediastrum simplex were dominant species in the waterbody; the water quality in the test pool was eutrophicated seriously. After ecological multi restoration (Daphnia magna Submerged plants Fish), the effect was significant with higher water quality. Phytoplankton biodiversity was increased, and Cyanobacteria were controlled effectively,and also Microcystis sp. was no longer the dominant species of waterbody.
