Based on the connection between the principle body and object, a framework for quantitative analysis of water resources carrying capacity in specific region is presented. According to the methodology, available natural water resources and production efficiency of water use are two decisive factors of water carrying capacity. The water resources carrying capacity can be figured out and expressed by amount of inhabitants with respective gross production. Further more, that critical threshold value is under predefined living standard, different living standard ascertain corresponding carrying capacity value. Finally, a case study for an island demonstrates the concrete approaches in this methodology.
