中文摘要	以和田河流域绿洲区地下水污染调查数据为基础,对地下水三氮的污染状况及影响因素进行了研究.结果表明,和田河流域绿洲区地下水三氮污染不是很严重,但随时间呈不断加重的趋势.硝酸盐氮是绿洲区地下水中三氮的主要存在形态,其含量、检出率和超标率最高,氨氮次之,亚硝酸盐氮最低.地下水中三氮含量的空间分布表现出一定的规律性,水平方向上,绿洲南部硝酸盐氮和亚硝酸盐氮的含量普遍高于绿洲北部,而氨氮在北部的分布范围比南部广;垂直方向上,浅层潜水中三氮的含量高于中深层潜水;与新疆其他地区相比,和田河流域绿洲区地下水中硝酸盐氮含量较高,亚硝酸盐氮和氨氮含量较低.绿洲区地下水中三氮的来源主要与居民日常生活和农业生产有关,其存在形态和分布特征主要与水化学环境、包气带岩性和厚度及地下水径流条件等因素有关.
英文摘要	Based on groundwater pollution survey data,the pollution status and influencing factors of Three-Nitrogenin groundwater were investigated in the oasis area of Hotan River basin. The reeults showed thatThree-Nitrogenpollution of groundwater in the oasis area of Hotan river basin was not serious,but increased over time. The content,detection rate and over standard rate of nitrate nitrogen were the highest,followed by ammonia nitrogen,and nitrite nitrogen was lowest in the groundwater. The spatial distribution ofThree-Nitrogencontent in the study area showed some pattern. In the horizontal direction,the content of nitrate nitrogen and ammonia nitrogen decreased gradually from south to north,but the distribution of ammonia nitrogen in the north was wider than that in the south. In the vertical direction,Three-Nitrogencontent in the middle-deep unconfined groundwater area was higher than that in the shallow unconfined groundwater. Compared with other regions in Xinxiang,the content of nitrate nitrogen in the oasis area of Hogan river basin was high, while the content of nitrite nitrogen and ammonia nitrogen were low. The sources of Three- Nitrogenwere mainly related to resident life and agricultural production.There were many factors that influenced the form and distribution characteristics ofThree-Nitrogenin groundwater,which include the lithology and thickness of aeration zone,hydrochemical environment and groundwater runoff conditions.
