Abstract: The paper comprehensively analyses on the geoenvironment survey results of the coastal zones in Liaoning Province over the past 20 years, and systematically sorts out the geological resources and environmental conditions and their changes, as well as the adverse environmental geological problems caused by natural and human activities in the coastal zones. The geoenvironment conditions of 6 coastal cities are evaluated in terms of geological factors such as crustal stability, active fault, ground subsidence and collapse, and suggestions are put forward for the protection, exploitation and utilization of geological resources in combination with national policies and local development plans.
