| 摘 要： | 生态需水是当前水问题的一个研究热点,对于生态环境急剧恶化的内陆干旱区,这一研究尤为紧迫.以额济纳绿洲为例,采用潜水蒸发模型,对其生态用水进行了估算.结果表明:2000年额济纳绿洲生态需水量为5.0009×108m3;2010年绿洲生态需水量为5.8342 × 108m3;2020年绿洲生态需水量6.8768×108m3...

| Abstract: | Ecological water demand is one of the hotspots in water issues,especially in the arid areas whose eco-environmental condition is sharply deteriorated.As a case of study,using the groundwater evaporation model we calculated ecological water requirements of Ejina Oasis.The results indicated that the minimum ecological water demand is 5.0009×108m3 in 2000,5.8342×108m3 in 2010,6.8768×108m3 in 2020.If the oasis area be regained to the level in 2010 and in 2020,the incoming runoff through the Langxinshan section must be reached 7.5845×108m3 and 8.9398×108m3 respectively.Quantitative estimation and qualitative analysis of ecological water consumptions during different periods are of important significance and applicable for reference in scientifical1y working out the project of regenerating ecology and rationally redistributing water resources in arid and semiarid areas. |
