水资源高效管理是提高水资源动态管理的有效方式,是实现地表水、地下水、再生水等多水源联合调配.提高水资源利用效率的综合管理措施,为水资源合理配置和高效利用提供技术支撑。以石羊河流域为研究对象.基于MIKEBASIN模型,根据研究区降水、蒸发和用水等资料,建立了石羊河流域水资源管理模型,模拟了石羊河流域径流量、水库和灌区需用水量变化特征。从模拟结果可以看出,所建立的水资源管理模型是正确的.选取的参数和计算的结果基本合理.模拟结果总体上反映了流域水资源变化状况.符合石羊河流域水资源的实际情况。通过模型预测了2015与2020年流域需水量,从预测结果可以看出,2015年较2010年减少23572.19×10^4m^3,2020年较2015年减少20926.77×10^4m^3,说明整体上流域需水量呈下降趋势。
The water resources high-effective management is effective mode for improving water resources dynamic management, and is comprehensive management measures for realizing conjunctive regulation for surface water, groundwater, reuse water and multiple sources of water and improving water resources utilization efficiency, which will offer technical support for water resources rational collocation and high- effective using. Taking Shiyanghe River as the study case,according to precipitation, evaporation and water use data, the water resources management model was established based on MIKE BASIN, and variation characteristics of runoff, reservoirs and water demand and used of irrigated area were simulated in the Shiyanghe River Basin. The results show that water resources management model is correct and the chosen parameter and calculated results are reasonable. The simulation results reflect variation of water resources and accord with the condition of the Shiyanghe River. The water demands in 2015 and 2020 were forecasted with MIKE BASIN model. The forecasted results show that water demands taken on downtrend from 2010 to 2020 in the Shiyanghe River. The water demands decreased by 23572.19×10^4m^3 in 2015 than those in 2010, and will decrease by 20926.77×10^4m^3 in 2020 than those in 2015, which means the water demands show a decrease trend.
