本文介绍南极拉斯曼丘陵湖泊水化学特征。对１３个湖泊的调查和统计分析表明，湖水以Ｎａ＋和Ｃｌ－为主要优势离子，不含有ＣＯ３２－离子，营养物质（Ｎ、Ｐ、ＳｉＯ２）在湖水中普遍偏低，而且湖水和雪样无机氮组分均以ＮＨ４＋为主，水化学类型比较单一，都属氯化物Ｎａ＋型贫营养水体。Ｎａ＋、Ｃｌ－、ＳＯ４２－的高浓度，特别是Ｂｉｇ湖、莫愁湖和Ｈｅａｒｔ湖水中离子含量明显的高，指示拉斯曼丘陵地区的降水来源以海洋气团为主，并受海洋环境影响强烈。微量元素分布在０．０１～２．０μｇ／ｌ之间，接近于水圈这些元素的浓度值。
This article describes the hydrochemical characteristics of the Lake Rathman Hills in Antarctica. The investigation and statistical analysis of 13 lakes show that Na + and Cl- are dominant ions in the lake, and do not contain CO32- ions. The nutrients (N, P and SiO2) are generally low in lakes, and lake and snow-like inorganic Nitrogen components are mainly NH4 +, water chemistry is relatively simple, are chloride Na + type of poor nutrient water. The high concentrations of Na +, Cl-, and SO42-, especially in Big Lake, Mochou Lake and Heart Lake, indicate that the source of precipitation in the Rathman Hills is dominated by marine air masses and strongly influenced by the marine environment . Trace elements distributed in the range of 0.01 ~ 2.0μg / l, close to the value of the concentration of these elements in the hydrosphere.
