The integration of Beijing-Tianjin-Hebei is an important national strategy and a measure for the regional development. Since water resource is the important support and security of the economic and social development, the integration of water resource in Beijing-Tianjin-Hebei Region should be paid close attention and put into practice. However, the integration of water resource, as the scarce resource, need to be reasonably planned and organized. The integration of water resource is restricted by a lot of elements such as the balance of inter generation, inter government, industry requirement, household consumption and so on. Therefore, it is necessary to coordinate the relationship of these elements to accelerate the integration and security system of water resource.
