摘　　要：为探明吉林省查干湖湖泊水环境生态系统的特征,于2017年10月末(冬季)、2018年4月(春季)、7月(夏季)、9月(秋季)调查分析查干湖水生生物的种类与密度的变化及规律。调查的水生生物包括浮游植物、浮游动物以及底栖动物。调查结果表明:查干湖浮游植物74种,隶属于8门61属,夏季浮游植物栅藻属(Scenedesmus)占优势,冬季浮游植物小球藻属(Chlorella)占优势。浮游动物29种,隶属于17属,底栖动物共12种,湖泊中部底栖动物所含种类少,仅有水丝蚓(Limnodrilus)。In order to explore the characteristics of lake water environment ecosystem in Chagan lake, Jilin province, we investigated and analyzed the changes and rules of species and density of lake organisms in October(winter), April(spring), July(summer) and September(autumn) from 2017 to 2018. The survey included phytoplankton, zooplankton and benthos. The results showed that there are 74 species of phytoplankton in Chagan lake, belonging to 8 phyla and 61 genera. Scenedesmus is dominant in summer and Chlorella is dominant in winter. There are 29 species of zooplankton, belonging to 17 genera, 12 species of benthic fauna, and the species of benthic fauna are few in the middle of the Chagan Lake, only Limnodrilus.
