额济纳绿洲水资源变化状况

Summary of the Present Situation about the Changing of the Water Resources in the Ejina Oasis

通过对额济纳绿洲水资源变化状况的归纳、整理、分析,得出如下结论:(1)额济纳绿洲的水资源主要来自黑河;(2)人类对黑河水长期过量地蓄积与利用是导致该绿洲水资源减少的基本原因;(3)半个多世纪以来,额济纳绿洲地表水资源趋于减少,其今昔差异是惊人的;(4)在额济纳绿洲地下水资源补给量逐年减少的同时,地下水消耗量又在逐年增加,这2个方面的因素势必会加剧地下水位下降的速度以及泉水出水量的减少甚至干涸.

By concluding and arranging the present situation about the changing of the wafer resources in the Ejina oasis,a conclusion can be obtained as follows： （1）The water in the oasis mainly comes from the Heihe river. （2）The basic reasons for the reduction of water resources in the oasis are led by the water from Heihe used unreasonably. （3）Since more than half a century , the surface water in the oasis tends to reduce. The differences of the present amout of water and the past are amazing. （4）The groundwater resources in the oasis has declined year by year, while the total consumptive amount of the groundwater has kept increasing every year. Those two factors will aggravate the rate to decline the groundwater and the spring water, even dry up.
