近几十年来，由于与水资源分配有关的问题，不同水用户之间发生了越来越多的冲突。为了更好地配置水资源，本文采用最新的水权交易模型代替传统的水资源配置模型，并将其与两阶段区间参数随机规划模型（TISP）相结合。将组合模型应用于三江平原多区域、多水源、多用水户的实际情况，得到了该地区各用水户的最优承诺供水量。分析表明，较高的承诺水供应量对应于较高的效益，但也促进了额外的风险，因为水资源短缺，而较低的承诺水供应量对应于较低的效益，虽然它更有可能导致水资源浪费在高流入水平。该组合模型在水资源利用效益和缺水惩罚之间形成了有效的联系，使我们能够获得同时考虑效益和风险的最佳承诺水资源可用性。第二个结果是，水权交易模式可以提高水资源的利用效率，水资源通常从低效用水地区转移到高效用水地区，从而使所有地区受益。此外，在水权交易模式中，微观层面的自利动机可以在宏观层面的适应中产生，从而稳定水资源系统，降低因极端缺水而导致系统崩溃的可能性。
In recent decades, increasing conflicts have occurred between different water users because of issues related to water resource allocation. To better allocate water resources, this study adopts the latest water rights trading model instead of the traditional water resources allocation model and combines it with a two-stage interval-parameter stochastic programming model (TISP). The combined model was applied to the Sanjiang Plain with multi-area, multi-source, and multi-water users, and the optimized promised water availability for every user in the area was obtained. The analysis shows that a higher promised water availability corresponds to a higher benefit but also promotes additional risks because of water shortages, whereas a lower promised water availability corresponds to a lower benefit, although it is more likely to result in water waste at high inflow levels. The combined model formed an effective link between water use benefits and water deficiency punishments that enabled us to obtain an optimized promised water availability that considers benefits and risks simultaneously. The second result is that the water rights trading model can improve the utilization efficiency of water resources, which are typically transferred from inefficient water use areas to efficient water use areas, resulting in a benefit to all areas. Additionally, in the water rights trading model, self-profit motivation at a micro-level can emerge in adaptation at a macro-level, which stabilizes the water resource system and reduces the possibility of system collapse because of extreme water shortages.
