Abstract


This article Hongyashan Reservoir Shiyang River Basin , Gansu Province, for example , the reservoir ecology scheduling based instream flow balanced . Hongyashan Reservoir function adjusted necessity . Hongyashan Reservoir before and after the completion of the analysis and comparison , it is pointed out that the the downstream irrigation ecological problem has become the bottleneck of the current scheduling Hongyashan Reservoir ; , pointed out that the Hongyashan reservoir only play irrigation and flood control functions can not solve the lack of analysis of the the reservoir status quo scheduling mode the ecological deterioration of the Minqin oasis ; proposed irrigation, flood control through the the Hongyashan reservoir status quo irrigation, flood control dual function to be able to take into account changes in the eco - three functions to solve the contradiction between the irrigation area of social and economic benefits and ecological benefits . Build a the Hongyashan reservoir ecology scheduling model and scheduling . Water demand from the the reservoir downstream river ecological , against the the Hongyashan reservoir control regional macro water resources allocation and scheduling of ecological problems , raised the Hongyashan reservoir ecology dispatch from the reservoir downstream ecological water demand balance starting reservoir through the reservoir itself water level and the discharged volume adjusted to meet the reservoir downstream river ecosystem water demand , the reservoir water Supply Area irrigation water demand and requirements for flood control ; single Reservoir the virtual water Supply Area as calculated at the unit , to the irrigation area of supply and demand is relatively balanced as the objective function to reduce the negative impact of reservoir construction and operation of the ecological environment as a major constraint , to establish the Hongyashan reservoir ecology scheduling model and scheduling . FS algorithm to find a viable strategy for the whole process of a large number of reservoir operation period to develop the water level in the reservoir run program , the calculation of Zaixun excellent DDDP method , smaller objective function as the initial trajectory , to finalize the program as Optimized Reservoir water level running track. Using reservoir water level feasible trajectory effect , low water level of the reservoir is running, the discharged flow more uniform scheduling of the status quo . In annual reservoir operation scheduling , irrigation district water supply and demand basically achieve balanced (S_t General by ≈ D_t order ) .
