河流中需氧有机体大型无脊椎动物评价指标

【摘要】 根据辽河流域2005年29个调查点底栖动物数据及多年研究成果,以河流中高需氧、中需氧、低需氧条件下大型底栖动物分布特点为依据,研究编制了大型底栖动物需氧有机体百分率评价系统以及百分率评价标准,为更好的利用底栖动物监测水环境提出了一套新的评价方法。更多还原

【Abstract】 Based on the monitoring data of Liaohe River Basin in 2005,the percent assessment system and the percent assessment standard for the aerobic organism of large-sized benthic animals were researched according to the distributing characteristic of large-sized benthic animals under the conditions of high oxygen,middle oxygen and low oxygen in the rivers.A new assessment method was put forward for the water quality monitoring with benthic animals.更多还原
