基于水生生物的湖泊营养类型评价

TROPHIC TYPE EVALUATION BASE ON AQUATIC ORGANISMS FOR LAKE

水生生物是湖泊生态系统的重要组成部分,通过湖泊水生生物量可以得出湖泊所处的营养状态,本文以内蒙古乌梁素海为研究对象,在实测数据和调查数据的基础上,对乌梁素海的水生生物进行了评价分析。结果表明:乌梁素海浮游动物平均生物量为3.749mg/L,在3.5mg/L^8.0mg/L之间,属于富营养类型;底栖动物平均生物量为71.672g/m2,大于12 g/m2,属于富营养类型。

Aquatic organisms arc important component of Lake Ecosystem, and aquatic biomass can show trophic status of lake. Taken Wuliangsuhai Lake as research object, based on a large of measured data and survey data, Aquatic organisms of Wuliangsuhai Lake are evaluated and analyzed. The results showed that the average biomass of zooplankton is 3. 749mg / L, which is between 3.5 mg/ L and 8. 0 mg/ L, and which is a eutrophic type. The average biomass of zoobenthos is 71. 672g/m^2, which is more than 12 g/ m^2, and which is a eutrophic type.
