| 摘 要： | 2009年4-5月对抚河下游分流处及河口进行浮游生物及水质状况的调研,基于优势种评价法和污水生物系统法并结合化学评价对其富营养化状况进行评价.共检出11大类,230种浮游生物.生物优势种评价法与化学营养状况指标法分析均表明,抚河下游分流处、东支河口和西支河口水体均呈富营养型.污水生物系统评价结果表明,抚河下游分流处水体介于多污染带与β中污带之间;东支河口水体介于多污染带与β中污带中间;西支河口水体处于多污染带.与分流处相比,河口浮游生物密度激增,还增加了金藻、黄藻、甲藻等浮游植物种类,说明河口富营养化程度比分流处严重,其中金溪湖处河口营养化程度最严重. |

| Abstract: | The plankton community and water quality in Fuhe River estuary was investigated from April to May 2009.Based on the dominant species evaluation method and Saprobic System,combined with chemical assessment to evaluate the eutrophication of Fuhe River estuary. A total of 230 species plankton,which belong to 11 categories were identified. The dominant species method and Nutritional status of chemistry Index indicated that fall of the monitoring points tookon europhication.Saprobic System research shown that the forks of Fuhe River downstream and east branch estuary are between multi-pollution zone and β-mesosaprobic zone,while west branch estuary was in multi-pollution zone.Compare with the diversion,there were much more species and higher density in estuary. Estuaries also increased Chrysophyta,Xanthopyta and Pyrrophyt.These shown estuary europhication degree was heavier than Jiaoshi Dam,especially west branch estuary. |
