摘  要:
西藏是中国地热活动最强烈的地区,地热蕴藏量居中国首位,各种地热显示几乎遍及全区,有700多处,拉萨河谷地区是地热资源十分丰富的区域之一,羊八井温泉、日多温泉等著名的地热就分布在拉萨河谷地区。对分布在拉萨周边区域的羊八井温泉、日多温泉、德仲温泉、贾桑温泉等4个典型高原地热温泉水环境中的Zn、Co、Cr、Fe、Mo、Pb、As、Sb、Ni、Cd、Hg、Be、Cu、Mn、Se等15种主要金属元素的含量、分布情况进行了初步研究,评估了地热资源在开发利用过程中对周围环境的影响,提出了相应的环境影响控制对策。研究成果将为西藏高原地区地热资源的合理开发及其生态环境保护提供重要的参考和借鉴。

摘  要:
Tibet as the most violent areas of geothermal activities in China,the reserves of geothermal resources is China's first,various geothermal almost all over Tibet,there are more than seven hundreds. The Yangbajing Geothermal Field is the biggest wet steam field which is developing in China,the special quality of geothermal water attracted wide attention. This thesis analyzed the 15 kinds of main metal elements(as Zn,Co,Cr,Fe,Mo,Pb,As,Sb,Ni,Cd,Hg,Be,Cu,Mn,Se etc.) in four geothermal water(as the Yangbajing Hot Springs,the Riduo Hot Springs,the Dezhong Hot Springs,the Jiasang Hot Springs). The impact of geothermal resources on the surrounding environment in the process of utilization was evaluated. Several measures to control the impact on the surrounding environment were put forward. Research results will provide important reference for reasonable development of geothermal resources in Tibet Plateau and eco-environmental protection.
