皮墨垦区224团水盐动态变化及水化学分析

Dynamic Changes of Water and Salt and It's Chemical Analysis of Groundwater in 224 Farm of Pimo Reclamation Regions

皮墨垦区位于塔克拉玛干沙漠边缘,是南疆典型的荒漠绿洲,生态极其脆弱。针对该绿洲土壤次生盐渍化发生严重的现状,通过对项目区地下水埋深及地下水矿化度的连续监测,以期研究探讨垦区的地下水盐动态变化规律及水化学特征。初步表明:垦区地下水埋深和矿化度均存在时间和空间上的变化,地下水水化学类型也具有明显的时空分布特征。

Because of locating on the edge of the taklamakan desert, Pimo reclamation region is one of the typical dry-desert areas, its ecological environment is frailty. According to a year monitor data of water and salt in Pimo reclamation regions, the dynamic chan- ges of water and salt and chemical characteristics was discussed. The results indicated that Changes of groundwater depth and miner- alization existed temporal and spatial rule, meanwhile, so was the chemical characteristics of groundwater.
