摘要
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。
The research area is 5-km region from Dong-daqiao Station to Ta-qiaozi station in Aqikesu River which belongs to Ebinur lake Wetland Nature Reserve.Groundwater measure point was mining.Groundwater samples were collected within the test points of P.euphratica in the community of Sino-German Cooperation Projects and also in the typical vegetations asuch as reed,Haloxylon and Tamarix along the banks of Aqikesu River.Through measuring the indicators of selected groundwater in the laboratory,such as the salinity and the major ion composition,we obtained the results.It was showed that K^＋ is closely related to the salinity,but the content of which is very low,its among the range of 0.0017g/L-0.0686g/L;However,the content of Na^＋ is a little high;SO4^2- and Cl^-play important rolls in salinity,and the content of them are both high among the negative ions;HCO3^- has no obvious related to the salinity of the groundwater.
