摘要
分别在2 0 0 3年枯水期与丰水期对洮儿河流域平原区潜水系统进行取样分析,运用空间变异函数和克立格插值法对潜水总溶解固体(TDS)时空变异特征分析,研究结果表明:(1)潜水TDS季节变化不明显,而且呈现明显的分带性;(2 )TDS空间变程较大,主要受区域水文地质条件、地形地貌、土壤类型等大尺度因子影响;(2 )局部地区潜水TDS出现异常,已受外界盐分污染。
Groundwater of the unconfined aquifer in Tao'er River Basin was systematically sampled and analyzed in dry and wet season in 2003, respectively, the methods of the spatial variograms and Kriging interpolation were applied to analyze the spatial and temporal variation characteristics of the total dissolved solids (TDS), the results indicate that (1) the values of TDS vary unconspicuously between seasons, but present clear patterns; (2) the range values of TDS is up to 64.8 km and 67.2 km, respectively, which are subject to the large scale factors such as hydrogeological conditions, topo-physiognomy and the type of soil and so on; (3) TDS represent abnormally due to saline pollution in the some area, but so far the activities of human being don't make the important influence on the quality of the regional groundwater.
