基于大凌河流域水生生物多样性指数调查与评估探究

Investigation and Analysis of Aquatic Biodiversity Index in Daling River Basin

水环境质量与水生生物分布具有十分密切的联系,水环境评价的重要标准之一为水生物的多样性指数[1]。文章通过调查试验的方式对大凌河流域水生生物多样性指数进行分析。调查结果表明:大凌河流域水生生物多样指数总体呈递增变化,水生生物密度在0.09-0.35之间,多样性指数在0.32-2.35之间。

The quality of water environment is closely related to the distribution of aquatic organisms,and one of the important criteria for water environment assessment is the diversity index of aquatic organisms.The aquatic biodiversity index of the Daling River Basin was analyzed through investigation and experiment.The survey results showed that the overall aquatic biodiversity index of the Daling River Basin showed an increasing change.The density of aquatic organisms was between 0.09 and 0.35,and the diversity index was between 0.32 and 2.35.
