摘　　要：20世纪50年代以来,额济纳地区生态环境不断恶化。本文分析了该地区环境演变的主要过程,即黑河水系不断溯源退缩和荒漠化不断发展的过程。并进一步探讨了该地区环境演变的驱动机制,在气候变化和人类活动的共同影响下,水环境的变化成为该地区环境演变的主要驱动力。最后为保护和恢复额济纳地区生态环境提出了相应对策措施。Since the 1950s, the environment of Ejina Region has been deteriorating continually. The environment changes of this region mainly referred to the processes of Heihe water system shrinking with tracing to the sources and rapid desertification. Based on the analysis above, the dynamic mechanism of the environment changes was revealed that the chief actuating force of the environment changes was the change of water environment caused by climate change and human activities. Furthermore, relevant coun- termeasures to protect and recover the ecological environment of this region were put forward.
