长江洞庭湖口原生动物的生态学研究
ECOLOGICAL STUDIES ON THE PROTOZOANS AT THE DONGTING LAKE OUTLET OF THE CHANGJIANG RIVER

摘要: 对长江洞庭湖口原生动物群落为期三年的研究结果:种类组成、季节分布、优势种类、丰度的季节变化等,同时还依据食性分析了各种类的功能营养类群,并对河流中原生动物的来源、长江中上游地区原生动物种类组成规律、原生动物功能营养类群和优势种类在河流污染监测中的指示作用等进行了讨论.Abstract: This paper reported the main study results of the protozoans at the Dongting Lake Outlet of the Changjiang River for a Period of three years.The species composition and seasonal distribution, dominant taxa, seasonal changes of total protozoan abundance were examined.Based on their food preferences, the identified protozoan species were classified to the functional-trophic groups.Additionally, the possible resources of the river protozoan species, characteristics of the protozoan species composition in the middle and upper reaches of the Changjiang River, as well as the indication values of both protozoan functional-trophic groups and the dominants in monitoring river water pollution were also discussed.
