The regulation of water resources in public basins is of great practical significance to deal with climate change and alleviate water resources conflicts. From the perspective of integration, according to different hydrological situations, the regulation of water resources in public basins can deal with complex and changeable climate change. This article uses DPSIR model to build the analysis framework of water resources system, and constructs its system dynamics model group to analyze the causal relationship of the water resource system from the perspective of supply and demand. Taking the Lancang-Mekong River Basin as an example, this article uses the system dynamics model to explore the current and future water resources supply and demand of the basin, analyzes its evolution process and regulation mechanism, and carries out simulation research combined with different hydrological scenarios. The results show that: there are great differences in the contradiction between supply and demand of water resources under different hydrological scenarios; Structural measures mainly affect the supply of water resources, while non structural measures mainly affect the demand of water resources. Both of the two types of measures can alleviate the pressure of water resources shortage, but for the more extreme hydrological scenarios, the pressure of water resources shortage will still appear in the future. When the structural measures and non structural measures are implemented at the same time, the supply of water resources has greater flexibility, even under the more extreme hydrological conditions, it can still adjust the balance between supply and demand of water resources, which is conducive to the long-term sustainable development of water resources in the basin. The research results reveal the regulation effect of water resources in different hydrological situations in the Lancang-Mekong River Basin from the perspective of integration, and the impact of various regulation measures on the supply and demand of water resources, which lays a foundation for the joint action of water resources regulation in the Lancang-Mekong River Basin.

Key words: DPSIR model, system dynamics, the Lancang-Mekong River Basin
