摘要
针对当前用水总量控制的社会命题,将经济学中的收益与赔偿概念引入到水资源优化配置体系中,以用水总量控制指标作为水资源配置的核心状态变量,建立了变化环境下基于用水总量控制的流域水资源优化配置报童模型,并应用于广东省东江流域,采用大系统分解协调原理对模型求解,得到研究区2020年生活用水控制指标高方案和低方案下的配水结果。结果表明,两种用水量控制指标方案下,流域各行业配水量相差不大,在特枯来水年份缺水严重,缺水率超过了50%,生活用水控制指标低方案较高方案获得的用水净收益大;模型较好地协调了东江流域来水、需水、用水总量控制指标与配水之间的效益关系,用水户用水净收益的变化特征反映了配水的合理性,证实了模型的可行性。
In view of the proposition of total water use control, this paper introduces the concepts of benefit and compensation from economics into water resources allocation. Based on the newsboy model, a multi-objective water allocation system that takes a total water use control quota as the core state variable of water allocation is constructed and applied in the Dongjiang river basin. The principle of decomposition and coordination for large-scale systems was adopted to solve the model, and it provided water distribution results in the schemes of high and low quotas for domestic water use control in 2020. The results show that in these schemes, the water volumes allocated to various sectors had minor differences but the net benefits at the low quota are higher than those at the high quota. And during an extreme dry year, the water deficit ratio exceeded 50%. This newsboy model coordinates well the beneficial relationship of available water resources, water demand and water use control quota versus water allocation. The improvement on net benefits of each water use sector reflects the rationality of water allocation and confirms the feasibility of this model.
