| 中文摘要: |
| 2009年6月和10月对乌江下游银盘水电站工程影响区域的鱼类现状进行了调查，共采集到鱼类77种，其中鲤科鱼类有45种，占种类数的58.44%，鳅科10种，占12.99%，鲿科11种，占14.29%。从彭水至白马鲤科鱼类所占比例逐渐增大，鲿科鱼类所占比例逐渐减小。排在前10位的数量优势种类依次为瓦氏黄颡鱼、、宜昌鳅鮀、大鳍鳠、圆筒吻鮈、蛇鮈、吻鮈、鲫、粗唇鮠和泉水鱼，它们占影响区域江段总数量的80.04%；重量优势种类依次为瓦氏黄颡鱼、铜鱼、吻鮈、南方鲇、圆筒吻鮈、鲤、大鳍鳠、墨头鱼、鲫和，它们占影响区域江段总重量的73.83%。结合工程建设造成的大坝阻隔，库区江段生境萎缩或丧失，以及坝下江段水文情势变化加剧、气体过饱和、下泄水温低等可能对鱼类资源的影响分析，提出增殖放流、过鱼设施建设、改进消能方案，以及优化调度规程等多项保护措施，达到保护鱼类资源，促使工程影响区的生态环境呈良性循环的目的。 |

| From June to October 2009，a survey on the fishery status was taken in Yinpan hydropower station reaches of Wujiang River. Fishes of 77 species were collected. The number of Cyprinidae species was 45，the proportion was 58. 44%; the number of Cobitidae species was 10，the proportion was 12. 99 %; the number of Bagridae species was 11，the proportion was 14. 29 %. From Pengshui to Baima，the proportion of Cyprinidae has been increasing，the proportion of Bagridae has been declining. The number of top ten were Pelteobagrus vachelli，Hemiculter Leucisculus，Gobiobotia filifer, Mystus macropterus, Rhinogobio cylindricus，Saurogohio dabryi，Rhinogohio typus，Carassius auratus，Leiocassis crassilabris，and Semilabeo prochilus，the proportion was 80. 04%. The weight of top ten were Pelteobagrus vachelli，Coreius heterodon，Rhinogobio typus，Silurus meridionalis，Rhinogobio cylindricus, Cyprinus(Cyprinus)carpio，Mystus macropterus，Garra pingi pingi，Carassius auratus，Hemiculter leucisculus，the proportion was 73.83%. To protect fish resources and promote the eco-system，the potential effects of the dam on fish and the conservation tactics has been discussed. |
