摘　　要：水库作为重要的农业灌溉水源,同时也在城市供水及地下水补给等方面承担着重要作用,水库的水体质量状况影响着农业生产及人民的生活,因此,评价水库水质状况尤为重要。为了解黄壁庄水库水质状况,选取黄壁庄水库中7个水质指标,利用主成分分析法对黄壁庄水库水质进行评价分析。根据综合得分可知,仅8月份水库水质状况相对较差,为Ⅲ类,7月、9月、10月为Ⅱ类,其余月份水质状况均为Ⅰ类,水库水体质量状况整体良好。研究发现,采用主成分分析法对水库水质进行评价可以客观地反映水体的水质状况,可为水库的综合利用、保护及治理提供一定依据。As an important agricultural irrigation water source,reservoir also plays an important role in urban water supply and groundwater recharge.The water quality of reservoir affects agricultural production and people's life,so it is particularly important to evaluate the water quality of reservoir.In order to understand the water quality of Huangbizhuang Reservoir,seven water quality indexes were selected to evaluate and analyze the water quality of Huangbizhuang Reservoir by principal component analysis.According to the comprehensive score,the water quality of the reservoir is relatively poor in August,which is class II,July,September and October are class II,and the water quality of the rest months is class I,and the water quality of the reservoir is generally good.It is found that the principal component analysis method can objectively reflect the water quality of the reservoir and provide a basis for the comprehensive utilization,protection and treatment of the reservoir.
