摘　　要：额济纳绿洲区是张掖、武威等重要经济区生态屏障。近50年以来,随着黑河中下游工农业经济的持续发展,用水量不断增加,致使进入下游的径流量不断减少,进而引起了下游额济纳绿洲区的一系列生态与环境问题。本文在分析地下水和地表水资源减少及变化特征原因的基础上,指出了额济纳绿洲区的生态环境恶化的严重程度,提出了解决和保护下游绿洲区生态与环境的途径。Ejna oasis is an important eco - barrier of Zhangye and Wuwei. In the recent fifty years, with the economic development of middle and lower reaches of Heihe River basin, the water demand is on the steady increase, so the water amount flowing to lower reaches of Heihe River basin is on the steady decrease. Thus it led to the eco - environment problems in Ejna oasis on lower reaches of Heihe River basin, and the eco - environment problems are critical. After analyzing the reason of groundwater and surface reducing, the paper puts out the ways solving and protecting eco -environment in Eina oasis.
