| 摘 要： | 于2006年10月至2008年7月对西津水库米埠坑网箱养殖区浮游植物进行两个年度共8次调查。第1年发现浮游植物6门53属,冬季出现种属最多,达到43属,春、夏季最少,为35属,浮游植物年平均数量为35.18×104 L-1,平均生物量为1.07 mg·L-1。第2年度采集到浮游植物6门47属,以春季出现种属最多,达到40属,夏季最少,为29属,第2年浮游植物年平均数量低于第1年,为19.77×104 L-1,生物量高于第1年,达到1.22 mg·L-1。综合营养指数评价结果显示,米埠坑网箱养殖区处于中营养水平,有向富营养化过渡的趋势。

| Abstract: | The effects of cage culture on phytonplankton in Xijin Reservoir were investigated.Eight surveys were conducted from October 2006 to July 2008.In the first year’s surveys,6 families and 53 genera were identified,of which 43 genera were found in winter and 35 genera in spring and summer.Species abundance was 35.2×104 ind·L-1 and biomass was 1.07 mg·L-1.In the second year’s surveys,6 families and 47 genera were identified,of which 40 genera were found in spring and 29 in summer.Species abundance in the second year(19.77×104 L-1) was relatively less than in the first year,while biomass(1.2 mg·L-1) was relatively higher compared to that in the first year.Trophic level index(TLI) based on chlorophyll-a,total nitrogen,total phosphorus,and Secchi Disk depth showed that water near the cage culture area was mesotrophic and had the potential of eutrophication. |
