中文摘要	民勤绿洲面临的生态危机已经受到人们的普遍关注.民勤绿洲出现生态危机的根源在于水资源危机,且危机还在进一步加剧.研究认为:民勤绿洲的地表来水量已经接近或达到最小极限,在今后的一段时间内将维持现有水平;地下水开采量超过原先的估计,但也会在较高的水平上保持稳定;地下水水质会进一步恶化,生态危机将会加剧.
英文摘要	Ecological crisis caused by more and more serious shortage of water resources in the Minqin Oasis has been extensively paid great attention to. This paper analyzes the exploitation and utilization of water resources in the Minqin Oasis, and it is considered that the surface water supply from the Shiyang River has been reduced to the minimum, and such situation will be continued in the future. Groundwater exploitation has exceeded the original estimation and caused the continuous ecological crisis. The estimated results reveal that the average annual volume of pumped groundwater is 5.972 110~8 m~3 in recent years, whereas the annual groundwater recharge is only 3.175 610~8 m~3. This means there is an annual groundwater loss of 2.796 5*10~8 m~3. In the Minqin Oasis, agricultural water consumption is dominant in water resources consumption. By comparing the volumes of supply and consumption of water resources, it is considered that the results of this study are reliable, that is the ecological crisis caused by shortage of water resources in the Minqin Oasis will become more and more serious, and groundwater quality will be continuously deteriorated. Thus, some measures should be put into practice. It is impossible to maintain the Minqin Oasis by relying on its available water resources. Parts of the oasis should be abandoned, especially the dried-up-lake regions.
