多布电站对尼洋河八一段水环境影响综合评价研究

Study on the Comprehensive Evaluation of the Influence of Duobu Hydropower Station on the Water Environment of Niyang River in Bayi

为了开展多布电站对尼洋河八一段水环境影响综合评价,文中采用了主成分分析法对2013年至2017年5年的逐月23项水质监测指标开展了评价。评价结果显示:水环境水平年内分布规律一致,其主要表现在曲线外形、年内水环境峰值和谷值的分布、丰枯水期水环境水平分布几乎一致;水环境水平年际分布显示,2014年水环境水平最好,2016年和2017年水环境水平有一定程度降低,其原因尚需进一步明确。

In order to carry out the comprehensive evaluation of Duobu Hydropower Station on the Water Environment of the Niyang River in Bayi, principal component analysis was used to evaluate the monthly 23 water quality monitoring indexes for five years from 2013 to 2017. The results showed that the distribution of water environment was consistent during the year, which is mainly manifested in the shape of curve, the distribution of peak and valley values of water environment in the year, and almost the same level of water environment in the abundant and dry season. The interannual distribution of water environment showed that the water environment level in 2014 was the best, and the water environment level in 2016 and 2017 were reduced to a certain extent. The reasons for the water environment need to be further clarified.
