通过选取新疆艾比湖湿地国家级自然保护区阿其克苏河东大桥管护站至塌桥子管护站15km为研究区域,野外分两次采样:在研究区内中德合作项目胡杨样地及垂直河道胡杨、柽柳混交林处采挖地下水测点,在典型植被芦苇、梭梭、柽柳及出露的泉水处采挖地下水测点,分别采集水样。实验室实测地下水矿化度及主要离子(K+、Na+、Ca2+、Mg2+、Cl-、CO23-、HCO3-、SO42-)含量,研究结果表明:与研究区地下水矿化度相关性最大的阳离子是K+,但其含量很小,在0.0017g/L-0.0686g/L之间;而Na+与矿化度的相关性次之,且含量较高,对地下水矿化度起主要作用的阴离子为SO42-,Cl-次之,且这两种离子含量在阴离子含量中均较高;而HCO 3-与地下水矿化度之间没有明显的相关关系。
By selecting 15km of Yaqia Suhe Dongda Bridge Pipe Station to Yaqiao Sub-tube Station in the Aibi Lake Wetland National Nature Reserve of Xinjiang as a research area, two samplings were made in the field: in the Populus euphratica And the vertical channel Populus euphratica and Tamarix chinensis mixed forest at the groundwater measuring point, the typical vegetation Phragmites australis, Haloxylon ammodendron and exposed spring water digging groundwater points, were collected water samples. The measured groundwater salinity and the contents of major ions (K +, Na +, Ca2 +, Mg2 +, Cl-, CO23-, HCO3-, SO42-) measured in the laboratory show that the cation with the highest correlation with the salinity of groundwater in the study area is K +, but its content is very small, between 0.0017g / L and 0.0686g / L; and the correlation between Na + and salinity is second, and the content is high. The anion that plays a major role in the salinity of groundwater is SO42 - and Cl-, and the content of both ions is higher in the anion content; however, there is no obvious correlation between HCO 3- and the salinity of groundwater.
