- 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.
