摘要
Carbon dioxide geological storage is one of the most effective ways to solve the issue of global greenhouse effects.It should be noted that CO 2 geological storage project may induce fractures,earthquakes,pollution of freshwater aquifers and other geological hazards which are harmful to human and ecological environment.The potential environmental geological problems caused by CO 2 geological storage and its genetic mechanism are analyzed respectively.Corresponding prevention measures are suggested from such aspects as risk assessment,monitoring and early warning and emergency reliefs.These are of important practical significance for safety assessment and management of CO 2 geological storage project.
