摘　　要：南方农田地下水有机污染源头既有化肥、农药残留,也受到农业生产废弃物等其他污染源的影响,导致地下水含有多种有机物质,使得分布特征分析复杂多变。从空间特征与时间特征展开研究。选取多个采样点,每个月在各采样点实施采样并计算各月均值。利用水文地质钻孔方法,采集各采样点的浅层地下水水样,测试有机污染物包括农药、SVOCs、VOCs的含量,同时采样不同时期的附近浅层地下水水样,分析农药污染时间分布特征。根据分析结果可知,研究地区浅层地下水有机污染与农田种类和周围污染源相关,污染浓度随农作物生长时期而变化。The source of organic pollution of groundwater in southern farmland is not only fertilizer and pesticide residues,but also other pollution sources such as agricultural production waste,which leads to the groundwater containing a variety of organic substances,making the analysis of distribution characteristics complicated and changeable.Therefore,the spacial and temporal characteristics are studied to select multiple sampling points.The sample are taken from each sampling point every month to calculate the average value.The hydrogeological drilling method was used to collect shallow groundwater samples at each sampling point to test the content of organic pollutants,including pesticides,SVOCs and VOCs.Meanwhile,the nearby shallow groundwater samples at different periods were sampled to analyze the temporal distribution characteristics of pesticide pollution.According to the analysis results,the organic pollution of shallow groundwater in the study area is related to the types of farmland and surrounding pollution sources,and the pollution concentration changes with the growth period of crops.
