中文摘要	氟是对生物圈、地圈及人类健康都具有重要影响的化学元素。2014年夏季和2015年冬季沿克里雅河上游山区-中游于田人工绿洲-尾闾沙漠腹地达里雅布依天然湖沼湿地采集测定了1个乌鲁克库勒湖水、21个河水和8个地下水样品的F~-、pH和TDS(可溶性固体总量)。测得流域河水F~-含量在0.09~6.08 mg? L~(-1),地下水在2.68~6.0 mg· L~(-1),高山湖为4.81 mg? L~(-1);河水和地下水pH分别在7.28~8.60和7.26~7.87,湖水为8.95;河水和地下水TDS分别在216~2884 mg? L~(-1)与1113~3884 mg? L~(-1),湖水为17281 mg· L~(-1)。结果显示:①上游乌鲁克库勒湖为高F~-、高矿化度碱性盐湖;②在上游,克里雅河地表水各参数基本不受季节影响,但中、下游因洪水期,除pH以外,夏季F~-、电导率、TDS和硬度等参数均低于冬季,而冬季中下游河水则因枯水期地下水的补给,氟化明显;③因蒸发和溶解等作用,自上游至下游,河水F-及TDS总体呈逐渐增加趋势,其中,上游河道F~-远低于中游于田人工绿洲及尾闾达里雅布依天然湖沼湿地的地下水,而于田绿洲地下水F~-含量反高于达里雅布依,或因苏打盐渍化引起;④流域水中F与TDS之间存在一定相关性,与pH间相关但不显著;⑤本流域F~-含量略高于阿克苏河及叶尔羌河等塔里木盆地其他河流。
英文摘要	Fluoride is a chemical element with important effects on the biosphere, lithosphere and human health. In this study ,21 surface water samples, 8 groundwater samples and 1 lake water sample were collected from the Keriya River Basin and the Ulugkol Lake in the Kunlun Mountains in northern marginal zone of the Tibetan Plateau in different seasons from 2014 to 2015. The fluorion content, pH values and total dissolved solids ( TDS) were measured. The fluorion content of surface water varied from 0. 09 and 6. 08 mg ? L~(-1),that of groundwater ranged from 2. 68 to 6. 0 mg ? L~(-1),and that of lake water was measured as 4. 81 mg ? L~(-1). The measured pH values of surface water and groundwater varied from 7. 28 to 8. 60 and from 7. 26 to 7. 87 respectively,and the measured pH value of lake water was 8. 95. The TDS of surface water and groundwater ranged from 216 to 2 884 mg ? L~(-1) and from 1 113 to 3 884 mg ? L~(-1) respectively,and the TDS of lake water was 17 281 mg ? L~(-1). The results are as follows :① The Ulugkol was a lake with high fluorion content,high alkalinity and high salt content ;② There was basically no seasonal variation of chemical parameters of surface water in the upper reaches. In the middle and lower reaches,however,the fluorion content,EC value,TDS and water hardness ( excluding pH valuje ) were all notably lower in summer because of flood water dilution,and the fluorion content in river water was higher in winter due to groundwater recharge ;③ The fluorion content and TDS of surface water from the upper to the lower reaches of the Keriya River was holistically increased because of the dissolution of chemical elements and water evaporation. The fluorion content in river water at the upper reaches was much lower than that in the Yutian Oasis and the Daryaboy Oasis. However, the fluorion content in groundwater in the former was higher than that in the latter because of soda salinization ;④ There was a good correlation between the fluorion content in river water and groundwater and TDS, but not between it and pH value ;⑤ The fluorion content in the Keriya River Basin was slightly higher than that in other drainage basins in the Tarim Basin, such as the Aksu River Basin and the Yarkant River Basin.
