摘要:
在黑河流域水资源开发利用过程中，人们只重视河流的经济效益而忽略了河流系统的生态环境需求，导致严重的生态环境问题随之而生。为了减少水资源开发利用过程中的生态环境问题，提出河道生态环境需水量的概念和计算方法，计算结果显示：黑河流域河道生态环境需水量为10.44亿m3/a，其中莺落峡生态环境需水量为4.755亿m3/a，约占河流地表水资源来水量的30%，正义峡生态环境需水量为3.06亿m3/a，约占河流地表水资源来水量的30%。考虑到其他因素，实际的生态环境需水量可能比计算结果要大。研究结果表明：黑河流域水资源利用率非常高，如何调控水资源开发利用，减少潜在生态环境问题是当务之急。
Abstract:
In the history of water utilization and development in Heihe basin, attention has always been paid on the benefit we could get from rivers while environmental and ecological function of the river system used to be neglected. Thus the activities of water utilization and development were accompanied by more serious environmental and ecological problems. In order to reduce the environmental and ecological problems caused by water sources development and utilization, this paper has proposed concept of environmental and ecological water consumption and the calculating methods. The results of the calculation have shown that the environmental and ecological water consumption in Heihe basins is about 10.44×108 m3/a, about 4.755×108 m3/a in Yingluo gorge, about 3.06×108 m3/a in Zhengyi gorges. Thus the integrated water required for ecology and environment took up about 30% of the total water resources. However, there are still some aspects of environmental and ecological water consumption must be more than that we had calculated. According to this result, the current utilization rate of the basin is too high. It is on the urgency to control and adjust water development and utilization to eliminate those problems existed and to avoid the potential ecological or environmental crises that are still not clear.
