【摘要】 黑河下游地下水波动带是我国西北干旱区黑河下游实施生态输水工程后出现的地下水位及其辐射范围变化明显的区域。其区域范围会随生态输水工程的实施而变化。本文在GIS技术支持下,通过对黑河下游生态输水前后地下水位空间连续分布及其变化的分析,进而对自生态输水实施以来到2005年输水结束背景下形成的黑河下游地下水波动带范围进行了探索性分析。结果表明,黑河下游地下水波动带大致在河流15km缓冲带附近。该研究可为黑河下游生态输水的环境效应分析及区域生态恢复提供参考。GIS技术为黑河下游地下水波动带范围分析及连续空间地下水的变化分析提供了有效手段。更多还原

【Abstract】 The groundwater-fluctuating region in the lower reaches of Heihe River is a region where the groundwater varies sharply in groundwater level and radiation range. It appeared in the background of ecological water delivering for improving environmental problem in the lower reaches of Heihe River, northwest China. The range of the groundwater-fluctuating region will change with the implement of ecological water delivering. So, it is difficult to confirm the exact range of the groundwater-fluctuating region. Under the support of GIS, this paper studied the distribution of groundwater level in uninterrupted space in the lower reaches of Heihe River and analyzed its change from ecological water delivering was implementing to the close of ecological water delivering in 2005. And the range of the groundwater-fluctuating region was confirmed based on these analyses. The conclusions indicated that the range of groundwater-fluctuating region lies about 15 km buffer zone of this river. This study will be help to analyze the environmental effect from ecological water delivering and provide referrence for ecosystem restoration in the lower reaches of Heihe River. GIS offered efficient facility for analyze the range of the groundwater-fluctuating region in the lower reaches of Heihe River and study the change of groundwater level and radiation range in uninterrupted space.更多还原
