ABSTRACT

With the gradual promotion of water ecological civilization construction and the implementation of the Beijing-Tianjin-Hebei integration strategy, Zhangjiakou's capital water conservation and ecological environment support function is increasingly prominent. This study analyzes the current state of the water function zones in the Olympic core area and establishes an evaluation indicator system for the water function zones using the Pressure-State-Response (PSR) model. Based on this analysis, response technologies are proposed to address influential factors such as social and economic structure, tourist population growth, and point and non-point source pollution. The response technologies include ecological protection and restoration of water function zones, comprehensive management of point and non-point source pollution, regulating tourist population levels, and scientifically planning urban development to alleviate human development pressures. In this paper, the concept of harmony and balance is coordinated with the health of rivers and lakes to formulate treatment measures, which provides technical basis for the government functional departments to coordinate social and economic development, strengthen the management of water functional areas, implement the strictest water resources management system and other work, and has certain social, economic and ecological benefits. On the other hand, the protection of water functional zones also provides technical support for the capital's water safety, the construction of Beijing-Tianjin-Hebei ecological support zone and the construction of the capital's water conservation functional zone.
