摘　　要：基于对克拉玛依地区减排林地下水水位及水质的监测结果,分析了减排林地下水动态变化特征,探讨了减排林地下水的合理生态水位。结果表明,减排林区地下水埋深出现了规律性分布,减排林区地下水埋深已由2005年的7.8m减小为2009年的4.6m,呈减小趋势。减排林地下水的矿化度由2005年的22.67g/L变化为2009年的5.35g/L。并统计了减排林地下水理化性质特征,表明地下水的水溶性盐的空间变化明显。根据减排林区主要植被生长状况与地下水埋深关系,得出减排林区地下水合理生态水位为2.5～5.0m。Based on the monitoring data of groundwater level and its quality in Karamay artificial carbon-dioxide-capture forest,the characteristics of groundwater dynamic change were analyzed. Meanwhile,the reasonable ecological water table of groundwater in the artificial carbon-dioxide-capture forest was discussed. Results show that buried groundwater depth in the artificial carbon-dioxide-capture forest was regularly distributed and it was reduced from 7.8 m in 2005 to 4.6 m in 2009. Groundwater mineralization changed from 22.67 g/L in 2005 to 5.35 g/L in 2009. Statistics of groundwater physicochemical properties indicated that the spatial variation of water-soluble salts in groundwater was obvious. According to relationship between the main forest vegetation growth conditions and buried groundwater depth,the reasonable ecological water table of groundwater in Karamay artificial carbon-dioxide-capture forest was 2.5～5.0 m.
