中文摘要	南海湖位于蒙新高原,是寒旱区的代表性湖泊之一,由于人为污染,目前其水体处于Ⅴ类或劣Ⅴ类水质。为控制南海湖水体恶化趋势,为南海湖水体富营养化治理提供理论依据,该研究首先对南海湖2018年的水质数据及氮素类营养盐含量进行综合分析,结果发现南海湖水体污染物明显呈现出冬季高夏季低的变化规律;其次对各形态氮含量年内变化规律分析发现,水体中氮素类营养盐以有机氮含量最高,占总氮含量的50%左右,其次为NH_3-N,而NO_2~--N、NO_3 ~--N含量较少,对水体中总氮含量不足以造成明显影响;然后利用ArcGIS中的克里金插值法绘制南海湖各形态氮分布规律,分布结果显示各形态氮含量表现出一定的分布差异,TN、 NH_3~-N则表现出明显的分布一致性。最后,利用SPSS对数据进行可靠性分析,在保证数据可靠的前提下对水体的水质数据及营养盐含量进行相关性分析和多元线性回归分析,结果表明,温度对水质参数及氮素类营养盐含量具有显著影响,尤其以ORP、DOsat、TN、 NH_3~-N最为明显。
英文摘要	Nanhai Lake is located in the Inner Mongolia and Xinjiang plateau, one of the typical lakes in cold-arid area. Because of man-made pollution, the water quality is in Grade Ⅴ or worse than Ⅴ. In order to control the deterioration trend of the water quality as well as provide theoretical basis for the eutrophication treatment, this study first analyzed the water quality data and nitrogen nutrient content of the Lake in 2018, and it was found that the pollutant content is high in winter and low in summer. According to the analysis of the annual variation rule of various forms of nitrogen content, organic nitrogen has the highest content of nitrogen nutrients in water, accounting for about 50% of the TN, followed by NH_3~-N, and NO_2~--N, NO_3~--N is not enough to make a significant impact to the TN in the water. The Kriging interpolation method in ArcGIS was used to draw the distribution of various forms nitrogen in the Lake. The distribution results indicated that various forms of nitrogen content showed certain distribution differences, while TN and NH_3~-N showed obvious distribution consistency. Finally, the SPSS analysis was used for data reliability. On the premise of credibility of the data of water quality and nutrient content, correlation analysis and multiple linear regression analysis results showed that the temperature for the water quality and nitrogen nutrient content has a significant impact, especially with ORP, DOsat, TN, NH_3~-N is most obvious.
