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216~2 884 mg·L~(-1)与1 113~3 884 mg·L~(-1),湖水为17 281 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。
Fluorine is a chemical element that has a significant impact on the biosphere, the geosphere and human health. The summer of 2014 and the winter of 2015 Along the upper reaches of the Kriya River in mountainous areas - Artificial oasis in the middle reaches of Yutian - The hinterland of the tail desert in Daliyabu According to the natural wetland wetlands, 1 Urukkhu lake, 21 rivers and 8 Groundwater samples F-, pH and TDS (total soluble solids). The content of F- in river waters was 0.09 ~ 6.08 mg · L -1, the groundwater was 2.68 ~ 6.0 mg · L -1 and the alpine lake was 4.81 mg · L -1. The water and groundwater The pH values were 7.28-8.60 and 7.26-7.87 respectively, and the lake water was 8.95. The TDS of river water and groundwater were respectively 216-2884 mg · L -1 and 113.3884 mg · L -1, 17 281 mg · L -1. The results show that: (1) Upper Urukkule Lake is a high-F-, high-salinity alkaline salt lake; (2) In the upper reaches, the Keliya River surface water parameters are basically not affected by the season, but due to flood season, In addition to pH, the F-, conductivity, TDS and hardness parameters in summer were lower than those in winter, while in middle and lower winter of the river, the fluoridation was obvious due to the recharge of groundwater during the dry season. 3 Due to the evaporation and dissolution, The F- and TDS of the river water generally increased gradually, of which the F- content of the upper reaches of the river was much lower than that of the artificial oasis in the middle reaches and Daria-Yabu in the natural lakes and wetlands. Liyaubi, or silage salinization; 4 There is a certain correlation between F- and TDS in river waters, but not significant with pH; F-content in 5 basins is slightly higher than those in Tarim Basin such as Aksu River and Yarkand River Other rivers.
