| 摘 要： | 在 CHINARE- 1 5考察期间对中山站及毗邻地区的湖泊和冰雪进行了采样。它们的CODMn指数与中国《地面水环境质量标准》相比 ,可分为三类 :一类水质所占比重最大 ,大约为56% ,二类和三类分别为 37%、7%。各类水体的 CODMn指数主要为自然源所贡献 ,人为污染不明显。湖水的 CODMn指数是生物生长状况、有机质含量、盐度和水体氧化还原程度的综合体现 ,新鲜降雪样的 CODMn指数指示了该地区的大气洁净度。

| Abstract: | WT5BZ]During the CHINARE 15, lake waters,ice and snow had been sampled in the Zhongshan Station and its adjacent area, Antarctica. Compared with Environmental Quality Standard for Surface Water(China,GB3838 88),their COD Mn had been divided into three groups. Many of them (about 56%) are under the first type of quality standard, and the other are under the second and the third type,37% and 7%, respectively. The most important factor affecting the values of COD Mn was natural source, and the pollution coming from the human activity was not serious. The values of COD Mn for lake water showed the situation of biological growth, the content of organic substance, salinity and the extent of oxidation and reduction for water. On the other hand, the COD Mn of fresh snow is the index of the atmospheric pollution for this area. |
