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 results of groundwater level and water quality in emission reduction forest in Karamay region, the dynamic change characteristics of groundwater in reducing forest was analyzed, and the reasonable ecological water level of groundwater in reducing emissions was discussed. The results show that there is a regular distribution of groundwater depth in forest areas with reduced emission, and the groundwater depth in reduced forest areas has been reduced from 7.8m in 2005 to 4.6m in 2009, showing a decreasing trend. The salinity of groundwater in the emission reduction forest changed from 22.67g / L in 2005 to 5.35g / L in 2009. The characteristics of physical and chemical properties of groundwater in reducing emissions are also calculated, which shows that the spatial variation of water-soluble salts in groundwater is obvious. According to the relationship between the growth of main vegetation and the depth of groundwater in the reduced forest area, it is concluded that the reasonable ecological water level of groundwater in the reduced forest area is 2.5 ~ 5.0m.
