摘要

摘要: 在大量实测资料的基础上, 建立了额济纳盆地地下水流系统饱和-非饱和三维数值模型, 对4种不同输水量情况下盆地内区域地下水位的变化趋势进行了预测, 进而提出了合理的输水方案, 黑河上中游向额济纳盆地合理的输水总量应为7.5亿m³/a, 其中通过狼心山水文站的水量不应小于5.5亿m³/a.这一方案为流域水资源的合理调配及额济纳绿洲生态环境保护和建设提供了依据.

Abstract: A large number of exploration and monitoring data in this paper show that a comprehensive groundwater system in the regimes characteristics of the interlayers between saturation and unsaturation is simulated using 3-D numerical model. The change in groundwater level is also predicted when surface water is delivered under four different scenarios. Subsequently, optimal scenarios of the surface water diversion are proposed, and the reasonable water output is 750 million m³/yr ranging from the upper-middle reaches of Heihe River to Ejina basin, in which the output water through Langxinshan hydrology is no less than 550 million m³/yr. It is expected that this study has great implications in the utilization and exploitation of groundwater resources, in the protection of ecosystem, as well as in the development in Ejina basin.
