| 摘 要： | 2007年8月16日与2010年8月3～5日,对泊湖4 000 hm2生态修复区的水生生物资源变化情况进行了调查。结果显示,时隔3年,泊湖生态修复区的的浮游植物增加了3属6种,细胞数和生物量分别增加了52.24×104L-1、0.370 8 mg.L-1;浮游动物增加了11属22种、生物量增加了11.031 mg.L-1;底栖动物虽然增加了4科11属13种、密度增加了21.2个.m-2,但因螺类等软体动物的平均密度与生物量分别降低了89.5%和90.5%,导致底栖动物总生物量下降了94.8%。沉水植物平均生物量仅断面Ⅰ略有增加,断面Ⅱ与Ⅲ呈下降趋势。综合分析认为,泊湖生态修复区水位升高持续数月不降,是导致该区域的水生生物种群结构和资源明显变化的主要原因。

| Abstract: | The investigation on hydrobios resource evolution in 4 000 hm2 Bohu lake ecosystem restoration area was conducted from 16th,August 2007 to 3rd-5th,August 2010 in Susong county.The result showed that after three years,phytoplankton in the area increased by 3 genera 6 species which were 52.24×104 L-1 in cell numbers and 0.3708 mg?L-1 in biomass.Zooplankton in the area increased by 11 genera 22 species which were 11.031 mg?L-1 in biomass.Zoobenthos increased by 4 families 11 genera 13 species and the density increased by 21.2 ind?m-2.Because the average density and biomass of snails decreased by 89% and 90.5% respectively,the total biomass of Zoobenthos dropped by 94.8%.The average biomass of submerged plant increased slightly only at Cross section I,but decreased at Cross section II and III.In summary,the raising of water level in Bohu lake eco-system restoration area was the main reason of the significant change on population structure and resource of hy-drobios. |
