海拨1940米的新疆天池公园是我国对外开放的高山湖泊自然保护区,具有明显的山地垂直景观带结构。吐鲁番盆地是我国海平面以下最低的地区,也是世界上少有的低地之一,具有独特的干旱区域自然景观。研究天山雪线—天池和吐鲁番盆地天然水化学元素的含量和组成,对揭示该地区的水质变化规律,评价人类活动对环境的影响程度,进一步发展旅游事业等有重要意义。

The natural background values of some waters from snow line of the Tien Mountain to Tien Lake region and Torupen Basin were measured by neutronactivation method.The results of measurement may be summarized as follows:Contents of rare earth elements(REE)from these areas ranged from n?0.001to n?0.01 ppb,and those of elements Au,Cs,Rb,Sb,W,and Cu ranged fromn?0.0001 to n?1 ppb.Uranium content has increased with decreasing altitudeabove sea level.It is possible to be relevant to the geochemical effect of rock.In addition,it has been found that the contents of Ca,Sr,Ba,Sc,Co,Cr,Fe,Se,Zn,etc.in well water at this area have been highly concentrated,Thereason about it was discussed in this paper.
