| 摘 要： | 对黑河流域水文资料进行分析计算发现, 由于有冰川补给流域水资源比较稳定, 最枯年和最丰年水资源量之比仅为1:2, 这在北方河流中是非常罕见的。多年平均水资源量为32.31亿m3·a-1, 人均水资源量为1689m3·a-1, 略低于国际上公认的人均水资源安全警戒线1000~1700m3·a-1的上限。根据黑河流域水资源反复转化多次重复利用的特点, 扣除7.5亿m3·a-1的生态用水量, 结合流域正在执行的综合整治和节水措施的推广, 目前水资源状况是安全的, 下游生态环境的危机可以通过水资源统一调配来解决。依据天然出山水资源变化和水土资源开发利用规模及额济纳旗生态环境状况, 在不增加土地灌溉规模并适当采取节水措施的前提下, 可以确定32.31亿m3·a-1的天然来水量为流域水资源安全临界线, 28亿m3·a-1的天然来水量为流域水资源安全警戒线。

| Abstract: | After analyzing the hydrological data for 58 years in Heihe river basin it was found that the regional water resources was relatively stable due to the replenishment of glacial melt-water. The ratio of the biggest annual runoff to the smallest one was 2:1, and the average water resources was 32.31×108 m3·a-1. The average per capita water reached (1 689) m3·a-1, which was within the world-accepted safety range of 1 000~1 700 m3·a-1. But among the water resources there are 7.5×108 m3·a-1 should be used for ecological consumption. With consideration to the characteristics of water resources being retransformed and reused for many times, and the water-saving measures being adopted in the whole river basin, the water resources was still within safety range. According to water resource status, land developmental scale and the eco-environmental situation, the threshold safety line of natural runoff resources in the study river basin is defined as 32.31×108 m3·a-1; and the safety cordon is 28×108 m3·a-1. |
