With the growth of global population and economic development, the contradiction between supply and demand of water resources is becoming increasingly prominent, and the shortage of water resources has become an important factor restricting social and economic development. Therefore, scientific and reasonable analysis of water resource supply and demand balance is of great significance to ensure the sustainable utilization of water resources. As an advanced water resources management tool, numerical simulation analysis can accurately evaluate the supply and demand of water resources through the simulation and prediction of water resources system, and provide scientific basis for rational allocation and effective management of water resources. Based on this, this paper discusses the connotation and characteristics of water resources supply and demand balance, analyzes the influencing factors of water resources supply and demand balance, and studies the numerical simulation analysis method of water resources supply and demand balance. Through numerical simulation analysis, the future water resource supply and demand situation can be predicted more accurately, and the changing law and trend of water resource supply and demand balance can be revealed. It is expected that the research in this paper can promote the development and application of numerical simulation analysis technology of water resource supply and demand balance and improve the level of water resource management.
