嘉陵江水电站对含沙量测验的影响

The Influence of Hydropower Station on Sand Content Detection in Jialing River

随着嘉陵江流域水电资源的开发,大规模兴建水利水电工程,各地抢占开发自然能源。但是,建设的水电站工程,导致天然河道的情况发生改变,不同程度的对泥沙进行了拦截,枯期的水样几乎清澈。文章以北碚水文站为例,从流域情况、水生态情况、电站情况、测站情况等多个方面介绍了嘉陵江流域上北碚水文测站的实际情况和影响因素,并提出了在电站影响后的北碚水文测站在枯季含沙量测验起止时间方面受到的影响,针对这一影响收集了该站的实测数据进行分析,并根据分析结果提出了合理的建议和意见。

With the development of hydropower resources in the Jialing River Basin,water conservancy projects have been continuously promoted,large-scale water conservancy and hydropower projects have been constructed,and the exploitation of natural energy has been seized everywhere.However,the construction of the hydropower project has caused changes in the natural river channel,and the sediment has been intercepted to varying degrees.The water samples during the dry season are almost transparent.Taking Beibei Hydrological Station as an example,this paper introduced the actual situation and the in- fluence factors of the Beibei Hydrological Detection Station in the Jialing River Basin from the aspects of watershed condi- tions,ecological water conditions,power station conditions and detection station conditions,and the influence of the sand content detection during the dry season of Beibei Hydrological Station.To address those influence,we collected the measured data from the station and proposed some suggestions and opinions based on the analysis results.
