火山喷发机制、气候效应及火山地球工程

Volcanoes are the link connecting the Earth' s interior and surface systems and are seen as a sign of the vitality of the Earth.Mitigating the impact of large volcanic eruptions on Earth' s climate and environment is a major topic in geosciences.In this paper we propose that in order to reduce the negative impact of volcanic disasters on all human beings, it is necessary to explore the incremental assembly and evolution of magma reservoirs, study the triggering mechanism of volcanic eruptions, focus on the interaction between the inner and outer layers of the Earth, and understand the feedback relationship between volcanic activity and global climate and surface environmental changes, and construct the theoretical system and technical framework of volcano geoengineering.Among them, the study of magma plumbing systems based on magma dynamics and volcanology will provide a new theoretical basis for the prediction and monitoring of volcanic activities.The influence of volcanic activity is global.Therefore, it must seize the opportunity to make progress in deepening the theoretical research on the mechanism of volcanic eruption and building an engineering technology system to reduce the impact of volcanic disasters.
