引汉济渭来水条件下西安市多水源联合调度
|
摘要
2020年引汉济渭调水工程即将引水进西安,西安市将形成多水源联合供水的局面,为此,提出了多水源联合调度的供水问题.通过对西安市区用水户和供水系统的分析,在确定了调度原则的基础上,构建了多水源联合调度仿真模型.根据西安市现有水源的供水规模,以及引汉济渭调水工程各受水区实际情况和调水量规划,为西安市假定了7种多水源联合调度方案,得出不同方案下多水源联合调度结果,水平年2020年,调水量为4×10~8 m~3时,比不调水新增供水量3.1×10~8 m~3,占总需水量的20.3%;调水量为4×10~8 m~3时,比调水量为2×108 m3时新增工业供水量1.77×10~8 m~3.结果表明,工程通水后可有效缓解西安市水资源短缺状况,同时在改善河道生态环境和保证水库灌区灌溉需水方面发挥重要作用.
As the Hanjiang River-to-Weihe River water transfer project diverts water into Xi'an in 2020,problems of joint operation would be proposed with chances of fulfilling water supply on multiple water sources conditions.Based on analyzing the characteristics of users and water supply system in Xi'an city,operation rules are determined.The multiple water sources simulation operation model is established;and the objective is to satisfy the water demand of Xi'an city.According to the scale of water supply of the existing water Xi'an city,and each receiving area actual situation and water transfer planning of Hanjiang River-to-Weihe River water transfer project,seven joint operation of multiple water sources schemes are calculated;the results under different schemes are reached.In 2020,after diversion water 4×10~8 m~3,3.1×108 m3 more water can be supplied for intake area compared with no diversion project which is 20.3% of the total water requirement.Industrial water supply increase 1.77×108 m3 compared with diversion water2×10~8 m~3.The results indicate water shortage can be relieved effectively;and the diverted water plays a major role in improving ecological environment of the river and water requirement of reservoir irrigation.
