中文摘要	黑河向东西居延海分水后,下游地下水位和开采储量的变化引人关注.以1990-1999年的平均地下水位代表分水前状况,以2004年代表分水后的地下水位水平,选择典型区域对狼心山以下额济纳三角洲地下水位的变化进行分析.结果表明:分水后下游三角洲的地下水位有不同程度的上升,范围在0.2~0.4 m;相应地地下水可开采储量增加约0.17*10~8 m~3,分析得出,这部分增加的可开采水储量主要由当年分水所增加的入境水量转化而来.由于黑河下游三角洲特殊的地理环境背景,决定了黑河分水是一项长期而艰巨的任务.
英文摘要	The change of groundwater level and reserves in the lower reaches of the Heihe River is paid great attention to after redistributing water from the upper reaches to the East and West Juyan lakes since 2000.In this paper,the change of groundwater level in the Erjina Delta downstream from Langxinshan is analyzed by regarding the average groundwater level during the period from 1990 to 1999 as the situation before redistributing water and the groundwater level in 2004 as the situation after redistributing water.The results show that the groundwater level in the lower reaches of the Heihe River has been extensively risen,especially that in the Erjina Delta has been risen by 0.2～0.4 m.Along with the increase of groundwater level,the shrubs and herbaceous vegetation with shallow roots in the lower reaches of the Heihe River can be effectively regenerated while maintaining the riparian forests.Accordingly,the groundwater reserves has been increased by 1.7*10~8 m~3,which is mainly attributed by the direct increase of inflow from the upper reaches to the lower reaches.Water redistribution is a long-term project because of the arid climate,fragile riparian forests,unstable oasis environment and dependence of the desert natural vegetation to groundwater in the lower reaches of the Heihe River.
