独山子地区水资源耦合模型与优化配置研究

Research on the coupled model and optimization management for water resources in the Dushanzi area

摘要: 本文从水资源系统结构与用户需求分析入手,研究了地表水和地下水模型的耦合方法,构建了水资源目标规划模型,对独山子地区水资源进行了优化配置。研究表明:独山子地区水资源可以满足独山子区与灌区的现状需水要求。独山子区近期、中期、远期全部启动四个水源地供水仍不能满足需水要求,还需要外调水源补充解决,远期外调水已接近可调水资源量;为保证水源地有适量的河水入渗补给,限定了河道引水量,枯水年不能满足灌区的灌溉需水,平水年基本可以满足,丰水年完全能够满足。即使调水后,仍然要节水,提高灌溉效率。

Abstract: The structure for a water resources system and water demand is analyzed.Coupled modeling methods for surface and groundwater are studied.The objective management model of water resources is established.The optimization management for water resources in the Dushanzi area is carried out.The results show that water resources in the Dushanzi area can meet the demand of water supply for Dushanzi and irrigation for the area under the current situation.However,for the short-term,middle-term,and long-te...
