| Abstract | 伊塞克湖是世界最大内陆高原咸水湖泊之一， 湖水中的主要离子有硫酸盐、氯化物、钠和镁。湖水属于硫酸盐类与氯化物-硫酸钠-镁型矿化。由于计划的水资源管理活动与旅游业的发展有关， 因此有必要根据新的分析数据来分析伊赛克湖及其入湖河流的水化学组成及变化特征。本研究的主要目的是基于伊塞克湖水体监测数据对研究区水化学特征进行完整的描述。本研究利用以前研究中获得的长期水化学研究数据（1977,1986 年）以及 2014 年和 2016 年的实测数据进行分析。 2014 年中国科学院新疆生态与地理研究所采集了 19 个河流样点和 8 个湖泊样点的水样，并对其离子参数进行了分析。 2016 年又采集 20 个湖泊水样分析了 pH 值、亚硝酸盐氮、铵态氮、合成表面活性剂、石油产品、溶解氧、重金属-铜、锌、镉和铅等参数。本研究分析了 1986 年、 2014 年、 2016 年期间水的化学组成，结果表明，湖泊盆地的人为活动对沿湖地区和一些河流中水的化学成分会产生显著的影响，不良影响主要表现为水中高浓度的硫酸盐、 氯化物、氨和亚硝酸盐氮。巴里克西湾和湖泊东南部等湖盆面积不足的沿湖地区和河流受到的人为活动影响强烈。湖水中的主要离子如钠和钾的含量与 1932 年和 1986 年的含量相比略有增加，湖水的盐度含量从 1928 年的 5.823 g/l 增加到 2014 年的 6.22 g/l， 2014 年湖水pH 值变化范围在 7.95～8.82 之间。该研究结果向利益相关者提供了一个警告信号，伊塞克湖的水环境质量正在恶化，如果不减少污染源或提高水净化系统的有效性，就可能对人类健康和环境构成威胁。 |
| Other Abstract | The Lake Issyk-Kul is one of the largest highland and brackish lakes in the worldin continental origin. Sulfates, chlorides, sodium and magnesium are the predominantions of the lake water. The lake water belongs to the sulfate class and to the chloridesulphate-sodium-magnesium type of mineralization. In connection with the plannedwater management activities and the development of tourism, it became necessary tohighlight the hydrochemistry of the Lake Issyk-Kul and its basin on new analyticaldata.The main objective of this study was based on the complete description of thehydrochemical appearance and monitoring of the water bodies under consideration.For this purpose, the data of long-term hydrochemical studies obtained from previousresearches (1977, 1986). Furthermore, recent results related to the chemicalcomposition of the water in the Lake Issyk-Kul as obtained in 2014 by the XinjiangInstitute of Ecology and Geography, Chinese academy of sciences has been used.Water samples from 19 sites of rivers and 8 sites from the Lake were collected in 2014then ions parameters were analyzed. In 2016, water samples were collected in 20 sitesof the lake in order to analyses the following parameters: pH, nitrogen nitrite,ammonium nitrogen, Synthetic surfactants, petroleum products, dissolved oxygen,heavy metals - copper, zinc, cadmium and lead.The study analyzed the results of the chemical composition of water for theperiod 1986, 2014, 2016 and showed that anthropogenic activities in the lake basinimpacted significantly on the chemical composition of the water in the coastal zoneand some rivers. Adverse effects were expressed in high concentrations of sulfates,chlorides, ammonium and nitrogen nitrite. Inadequate areas of the lake basin, whichhave a strong anthropogenic effects, are Balykchy Bay, coastal areas of thesoutheastern part of the lake and rivers. The content of the main ions such as sodiumand potassium in the lake waters in comparison with 1932 and 1986 shows a slightincrease. The salinity of the lake water from 1928 to 2014 increased from 5.823 g/l to6.22 g/l respectively. The pH of the lake water was within 7.95-8.82 in 2014.The results provide a warning signal to stakeholders. There is a time-critical andgrowing deterioration in the quality of water, which can pose a threat to human healthand the environment in the absence of a reduction in pollution sources or the effectiveness of water purification systems. |
