| 中文摘要: |
| 2007-2011年对青海澜沧江上游水系的香曲、扎曲、子曲、巴曲进行了水生生物调查,共采集到浮游植物4门、53种,香曲、扎曲、子曲的浮游植物数量分别为13.85×104～34.20×104个/L、4.75×104～38.00×104个/L、22.17×104～206.93×104个/L,相应的生物量为0.2197～0.3489mg/L、0.1316～0.2456mg/L、0.1597～1.1260mg/L;浮游动物24种,香曲、扎曲、子曲的浮游动物数量分别为2.7～4.8个/L、1.1～26.6个/L、0.69～19.49个/L,生物量为0.0080～0.0720mg/L、0.0106～0.0564mg/L、0.0003～0.0165mg/L;底栖动物采集到16种;鱼类采集到6种,裸腹叶须鱼(Ptychobarbus kaznakovi)和前腹裸裂尻鱼(Schizopygopsis anteroventris)为优势种,鱼类生物多样性指数不高;初步探讨了渔业资源的变化,分析了其资源受威胁的因素,提出了保护与合理利用澜沧江水生生物资源的建议。 |

| A survey of aquatic organisms in upper stream of Lancang River(where the survey was mainly launched in the watershed of Zaqu，Xiangqu，Ziqu and Baqu ) was conducted from year 2007 to 2010. There were 4 phyla and 53 species of phytoplankton in total. Amounts of phytoplankton in Xiangqu，Zaqu and Ziqu were 13.85 x 104-34. 20 x 104 ind. /L, 4. 75 x 104一38. 00 x 104 ind. /L, and 22. 17 x 104一206. 93 x 104 ind. /L, respectively , and their corresponding biomasses were 0.2197一0.3489 mg/L, 0.1316-0. 2456 mg/L, and 0. 1597-1.1260 mg/L. There were 24 species of zooplankton. Amounts of zooplankton in Xiangqu，Zhaqu and Ziqu were2. 7一4. 8 ind. /L，1.1一26. 6 ind. /L，and 0. 69一19. 49 ind. /L，respectively，and their corresponding biomasses were 0.0080一0.0720 mg/L，0.0106一0.0564 mg/L，and 0.0003一0. 0165 mg/L. The number of benthonicanimal species was 16，and of fish species was 6. In conclusion，this study could provide useful suggestions on fish protection and utilization. |
