基于图木舒克市1 914 km~2范围内65组地下水水质的测试资料,分析地下水水质背景,运用Mapgis软件中克吕格插值方法,对图木舒克市地下水矿化度的分布特征进行研究,在同一位置,采取不同深度地下水样品,分析地下水在垂向上的变化规律。通过水质测试实验数据,得出由于受到补给来源、含水层岩性、地下水径流条件的影响,进入到图木舒克市区的的地下水,在山前带受到新近系地层的溶解影响,矿化度普遍偏高;在图木舒克市域范围内地下水矿化度在垂向上具有随深度的增加呈现出变大的趋势,而在水平方向上受河道、大型渠系工程的影响呈现出在河道、渠系两侧地下水矿化度小,远离河道、渠系处,矿化度变大的趋势。
Based on the test data of 65 groups of groundwater quality in the range of 1 914 km ~ 2 in Tumkuk city, the background of groundwater quality was analyzed and the distribution characteristics of groundwater salinity in Tumkuk city was analyzed by using Kriging interpolation method of Mapgis software Study, at the same location, take groundwater samples of different depths and analyze the vertical variation of groundwater. Based on the experimental data of water quality test, it is concluded that the groundwater entering the Tumukhuk urban area is affected by the dissolution of Neogene strata in the foreland zone due to the influence of recharge source, aquifer lithology and groundwater runoff. The degree of groundwater salinity in the Tumukhuk area tends to increase with the increase of depth in the vertical direction, but is affected by the channel and large-scale canal system in the horizontal direction in the river The degree of salinization of groundwater on both sides of the canal system is small, far away from the river channel and channel system, and the degree of salinity becomes larger.
