| Abstract: | 黑河流域是我国西北干旱区第二大内陆河，为了解决近几十年来该流域水资源开发利用过程中出现的一些不合理问题，利用翔实的资料系统分析了近50年来黑河流域中游地区水资源演变特征，并采用均衡法对地下水资源进行了评价。结果表明，自20世纪50年代以来，出山地表水径流量的年际变化相对比较稳定，没有明显的减少和增加趋势，由于随着中游地区工农业用水量的增加和水利化程度的日臻完善，地下水补给量明显减少，由20世纪50年代末36．5亿m^3／a减少到90年代末23．3亿m^3／a，由此引起了区域地下水位持续下降、泉水资源大幅度衰减等生态环境问题。[著者文摘]
Some irrational problems have appeared in water resources development and utilization in recent decades in the Black River basin, the second largest continental river in the arid region of Northwestern China. To solve problems, the characteristics and cau- ses of water resources evolution in the middle reaches of the basin in recent 50 years are analyzed systematically using the data collected from the basin, and the groundwater resources are evaluated by adopting water balance principle. The results indicate that the annual surface water runoff, coming from mountain areas of the basin, is comparatively stable since 1950s. while the groundwater recharge is decreasing along with the increase of industry and agricultural water uses and development of water conservancy in the middle reach zone of the basin. The groundwater recharge rate has reduced from 36.5 ×10^8 m^3/a in the end of 1950s to 23.3 × 10^8 m^3/ a in the end of 1990s, which induces many ecological environment problems such as sustaining descent of regional groundwater table and attenuation of spring water resources.[著者文摘] |
