Due to population growth and economic development, water demands for municipal, industrial, and agricultural users are increasing. It is a challenging and critical issue in water resources system to properly allocate and utilize water resources to satisfy the goals of different stakeholders and greenhouse gases mitigation. In this study, a hybrid life-cycle analysis and two-stage stochastic programming model was proposed to analyze the water-allocation strategies based on complicated urban water resource system. The hybrid model can effectively assess the low-carbon performance of an urban water resources system in the framework of life-cycle analysis. The environmental impacts and GHGs reduction of urban water resources were firstly considered as the objective and constraint for solving the water allocation problems. The results indicated that the first-stage solutions of surface water conveyance of Dalian could be [3.83×108, 8.25×108] in 2015, and [3.83×108, 9.21×108] in 2020; Meanwhile, the first-stage solutions of surface water conveyance of Dalian could be [4.26×108, 8.68×108] in 2015, and [5.35×108, 10.7×108] in 2020.
