用水生物评价与研究金沙江攀枝花段水环境污染

Assessment and Investigation of water Environmental Pollution in Panzhihua Reach of Jinshajiang River by aquatic organism

本文从生物学角度,应用生物指数(或数量)以及指示生物按枯、平、丰水期对金沙江攀枝花段各断面与年际(83年至86年)污染进行水环境评价。文章着重研究、探讨工业“三废”和生活污水对本口段生物群落结构、生长与繁殖所造成的影响,认为此江段属重金属、有机、霉物混合型中污染和轻污染。还用统计学方法对生物与理化监测结果进行相关分析,得到相关非常显著的四条回归曲线,为环境生物学预评价与污染防治提供了科学依据。

Water environments in g sections along Panzhihua reach of Jinshajiang River were assessed by using aquatic organism number and index organism in different seasons during 1983～1986. That three wastes from industry and domesting sewnge affected on the population structure, growth and reproduction of organisms was investigated. The result showed that water in the reach belonged to median arid slight mixing pollution resulting from heavy metals and toxic organic materials. Four regression curves, which are gotten by applying statistic method to analyse the results of biological, physical and chemical monitoring, are related very well. It provides the scientific basis for biological pre-assessment and pollution control.
