摘要 农业面源污染是农村饮用水水源地的主要污染因素,其中以硝酸盐污染问题最为突出。根据山东省沂水县域内279处地下水型农村饮用水水源地水质检测结果,本文从取水深度、海拔高程、地形坡度等3个方面对农村饮用水水源地的硝酸盐污染特性进行了系统研究。结果表明,水源地硝酸盐超标率和超标程度均会随着水源地取水深度、海拔高程以及地形坡度的升高而降低。研究结论可为主管部门采取有效的预防和治理措施提供借鉴,并可指导新建水源地的选址。 Agricultural non-point source pollution is the main pollution factor in rural drinking water sources, and nitrate pollution is the most prominent. According to the water quality test results of 279 groundwater-type rural drinking water sources in Yishui County, Shandong Province, the nitrate pollution characteristics of rural drinking water sources were systematically studied from three aspects of water intake depth, elevation above sea level and terrain slope. The results show that the rate and degree of nitrate exceeding the standard will decrease with the increase of water intake depth, elevation and terrain slope. The research conclusions can provide reference for the competent departments to take effective prevention and treatment measures, which can guide the location of new water sources.
