	<span style=\"font-size:14px;line-height:1.5;\">以安徽省耕地、水体环境保护以及人体健康为出发点，依据2001~2016年安徽省化肥、畜禽养殖以及人口数据，估算安徽省农业面源排放污染物的产生量，在此基础上计算耕地氮、磷和COD污染负荷、水体等标污染指数以及对地下水硝态氮的贡献程度。结果表明，安徽省整体耕地氮素、磷素污染负荷严重，预警级别均在Ⅲ级及以上；污染物对地表水污染呈现由南至北依次增加的趋势，北部最高，中东部次之；氮素会通过淋溶作用进入地下水导致硝态氮浓度升高，根据估算，超过80%的城市地下水硝态氮浓度存在超过20 mg？L<sup>？1</sup>的国家限定标准；地下水健康风险指数超过“1”的城市总共13座城市，占城市总数的76.5%，其中合肥风险指数最高，已经达到3.996，应注意饮用水质量。<br />
Based on the data of chemical fertilizer, livestock and population during 2001~2016 in Anhui province, the amount of agricultural non-point source pollutants emitted was estimated on the basis of the calculation of farmland nitrogen, phosphorus and COD pollution load, water, such as standard pollution index and contribution degree of groundwater nitrate. The results show that the nitrogen and phosphorus pollution load of the whole cultivated land in the province was serious, and the early warning level was in Grade III and above. The pollution of surface water from pollutants to the surface increased from south to north, with the highest in the north and the second in the middle and east. It is estimated that more than 80% of urban groundwater nitrate nitrogen concentration is more than 20 mg？L<sup>？1</sup> of the national limit. There is a total of 13 cities whose groundwater health risk index exceeds “1”, accounting for 76.5% of the total number of cities, among which Hefei city has the highest risk index, which has reached 3.996. Therefore, attention should be paid to the quality of drinking water.</span>
