察汗乌苏河水生生物的调查研究
|
摘要
察汗乌苏河是青海省四大内陆水系之一的柴达木水系的重要组成河流,关于察汗乌苏河水生生物的相关资料至今未见有详细报道.2014年8月至11月对察汗乌苏河的鱼类、浮游生物、底栖生物进行了较为详细的调查,采集到鱼类6种,434尾,浮游植物3门46种属,浮游动物3类4种属,底栖生物2种.浮游动物和浮游植物数量分别以轮虫和硅藻为优势种,浮游动物和浮游植物生量平均分别为0.0033mg/L和0.0512mg/L,整体体现出贫营养型河流的特征.
Chahanwusu river is an important component of the Chaidamu river system which is one of the four largest inland water systems in Qinghai province,until now there are no detailed reports on the biological data of the river in Chahanwusu river.From August to November in 2014,fish,plankton and benthos were investigated in detail,collected 6 species,434 tails of fish,3 genus,46 species of phytoplankton,3 genera,4 species of zooplankton and 2 species of benthos.The dominant species of rotifer and diatom,The average biomass of zooplankton and phytoplankton was 0.0033 mg/L and 0.0512 mg/L,the whole shows the characteristics of the plateau River poor nutrition.
