摘要

密云水库是首都最重要的地表饮用水源地,对保障首都供水安全具有重要意义。采用单因素评价法和Nemero污染指数,对密云水库流域汛期的39个地表水样和16个地下水样进行了水化学特征分析和水质分析评价,并应用地质探测器对水质指标和土地利用、气象、社会经济等空间数据进行了空间变异分析。结果表明:①地表水和地下水具有相似的水化学特征,具有紧密的水力联系、成分来源同源性、离子浓度空间分布不均匀等特点,地表水和地下水水化学离子可分别提取出3个主成分因子,主要受人类活动和岩石风化共同作用的影响。②水质评价结果表明,有15个采样点水质达到地表水二类标准和14水质采样点达到地表水第三类标准,还有七个地表水的水质采样点类Ⅳ标准,两类V,下层阶级,一个用于诉根据Nemero水质综合污染指数分级分类,类我有23个,二类14,III类和V类各有1个。高锰酸盐指数为主要超标指标,表明地表水存在有机污染风险。③人类活动是影响河流水质分异的主要因素,解释功率因子q值为0.204 9,降雨量和海拔高度对水质变化也有显著影响。双因子交互作用显著增强了河流水质空间分异的解释力,表现为增强或非线性增强,反映了流域层面的水质受到多个因子的共同影响。

[Analysis and Evaluation of Hydrochemical Characteristics and Its Driving Force in Miyun Reservoir Basin].

Miyun Reservoir is the most important surface drinking water source of the capital city, which is of great importance to guarantee the safety of the water supply in the capital city. A total of 39 surface water samples and 16 groundwater samples were collected in the field during the flood season in the Miyun Reservoir Basin to analyze the hydrochemical characteristics and to carry out water quality analysis and evaluation using the single-factor evaluation method and the Nemero Pollution Index and applying geo-detectors to analyze the spatial variability of the water quality indicators and spatial data, such as land use, meteorology, and socio-economics. The results showed that: ① Surface water and groundwater had similar hydrochemical characteristics, including close hydraulic connection, homology of component sources, and uneven spatial distribution of ion concentration, and three principal component factors could be extracted from surface water and groundwater hydrochemical ions, respectively, which were mainly affected by the combination of human activities and rock weathering. ② Water quality evaluation results showed that there were 15 water quality sampling points to meet the surface water class II standards and 14 water quality sampling points to meet the surface water class III standards, and there were seven water quality sampling points for the surface water class Ⅳ standards, two for class V, and one for inferior class V. According to the Nemero integrated pollution index classification of water quality categories, class I had 23, class II had 14, and class III and class V each had 1. The permanganate index was the main exceeding index, revealing that the surface water faced the risk of organic pollution. ③ Human activities were the main factors affecting the river water quality differentiation, with the explanatory power factor q-value of 0.204 9, and rainfall and elevation also had a significant impact on the water quality changes. Two-factor interaction significantly increased the explanatory power of the spatial differentiation of water quality in the river, which manifested itself as an enhancement or nonlinear enhancement, reflecting that the water quality of the basin level was affected by several factors together.
