摘    要:2014年春季、秋季对大渡河安谷水电站施工期浮游动物及水环境因子进行调查采样,利用Spss22和Canoco4.5软件进行数据分析。结果表明:大渡河安谷水电站施工期春、秋两季共检出浮游动物69属116种,密度平均为619.65ind./L、生物量平均是0.0930mg/L。左侧河网浮游动物种类、密度和生物量高于干流。浮游动物种类、密度、生物量和多样性指数在季节分布上差异显著,春季明显高于秋季。浮游动物种类、密度、生物量与环境因子硝氮、TN、磷酸盐、TP呈显著正相关,与流速呈负相关;RDA结果更进一步说明硝氮、磷酸盐、TN、TP是影响本次调查水域浮游动物群落结构的重要环境因子。水电工程建设给我们带来巨大的经济和社会效益的同时,对周围水生环境也产生了一定影响,安谷水电站施工期浮游动物密度和生物量高于环评期,一方面受施工影响,另一方面人类干扰过于频繁。所以我们要在保护中开发,做到人水和谐。

关 键 词:安谷水电站  施工期  浮游动物  环境因子  冗余分析

Abstract:The zooplankton and water environment factors in spring and autumn during the construction period of the Dagu River Angu Hydropower Station are investigated and sampled, and Spss22 and Canoco 4.5 software are used for data analysis. The results show: During the construction period of the Dagu River Angu Hydropower Station, 116 species and 69 genera of zooplankton are detected in spring and autumn. The average density is 619.65 ind./L and the average biomass is 0.0930 mg/L. The species, density and biomass of zooplankton in the river network on the left are higher than those in the mainstream. The species, density, biomass, and diversity index of zooplankton differed significantly in seasonal distribution, which is significantly higher in spring than in autumn. The species, density and biomass of zooplankton were positively correlated with environmental factors such as potassium nitrate, TN, phosphate and TP, and negatively correlated with the flow rate. The results of RDA further demonstrated that potassium nitrate, phosphate, TN and TP are important environmental factors that affect the community structure of zooplankton in the surveyed waters. The construction of hydropower project has brought great economic and social benefits to us, and also has a certain impact on the surrounding aquatic environment. The density and biomass of zooplankton during the construction period of Angu Hydropower Station are higher than that of the eia period. On the one hand, it is affected by the construction, on the other hand, human interference is too frequent. Therefore, we must develop in the protection and achieve harmony between people and water.
Keywords:Angu Hydropower Station  construction period  zooplankton  environmental factors  redundancy analysis
