中文摘要	从植被生长与地下水位的关系出发,将生态地下水位分为临界生态水位,适宜生态水位和最佳生态水位.结合生态地下水位,将干旱区非地带性植被生态需水量划分为临界生态需水量,适宜生态需水量和最佳生态需水量,并以潜水蒸发模型估算了额济纳绿洲植被生态需水量.结果表明:植被适宜生态需水量区间为4.3840108~14.10130108m3,最佳生态需水量为10.338108m3,满足最小生态需水量要求下的缺水量为2.8822108m3.要维持2000年的绿洲规模,狼心山站下泄水量应不小于5.6992*108m3.该研究对干旱区科学制定生态恢复方案和水量分配方案具有很大的现实意义和借鉴作用
英文摘要	The relationship between vegetative growth and underground water table was discussed. In arid region, ecological groundwater table(EGT) can be divided into critical EGT, fitted EGT and optimal EGT. Ecological water requirements(EWR) of non-belt vegetation can be divided into critical EWR, optimal EWR and fitted EWR.As a case of study, the EWR of plant in Ejina Oasis was calculated with the groundwater evaporation model. The results showed that the fitted EWR of plant was about 4.3840108-14.10130108m3, and that the optimal EWR of plant was about 10.338108m3.The shortage for meeting the minimum water requirement was about 2.8822108m3.If the oasis area keeps the level in 2000, the incoming runoff through the Langxinshan section must be more than 5.6992*108m3.It is applicable for reference in the project of regenerating ecology and rationally redistributing water resources in arid areas
