基于最严格水资源管理制度的要求，用水总量控制“红线”就是要强化水资源管理的约束力，促进水资源优化配置，提高用水效率，确保水资源可持续利用。基于“用水总量控制指标确定时应考虑当地水资源特性和当地社会经济及生态环境对水的需求两方面因素”的原则，系统讨论了狭义、广义及严格意义地表（地下）水资源可利用量的概念，提出了确定用水总量控制指标的方法体系。最后以胶南市及乳山市为例，计算了两市各规划年的用水总量控制指标，为两市用水总量控制制度建设和控制指标分配提供了依据。

Based on the requirement of the most strict water resources management system, the total water control “The Red Line” binding force is to strengthen water resources management, to promote the optimized allocation of water resources and water use efficiency, and to ensure the sustainable utilization of water resources. When determining the total water control index, two factors should be considered including the features of local water resources and the water demand of local socio-economic and ecological environment. In this paper, the concept of available surface (underground) water resources was discussed in three aspects of a narrow sense, generalized sense, and strict sense, and a method system to determine the total water use control was proposed. Finally, the total water control indexes in Jiaonan and Rushan during the planning year were calculated, which can provide a theoretical basis for the system construction of total water control and allocation of control indexes in the two cities.
