Abstract

Hydrogeological and environmental geological disasters, encompassing various types such as landslides, debris flows, and ground collapses, result from the combined effects of natural factors and human engineering activities. This paper focuses on these disasters, beginning with an introduction to common types including landslides and debris flows, land subsidence and collapse, and reservoir-induced seismicity. It provides an in-depth analysis of the multifaceted impacts of these disasters on the ecological environment, covering hydrological systems, soil environment, biodiversity, and long-term changes in geological structures. In response to these impacts, a series of ecological restoration measures are proposed, including engineering restoration, bioremediation, combined physical-chemical remediation, reconstruction of wetland ecosystems, and optimization of monitoring and early warning systems. The aim is to provide theoretical support and practical references for mitigating the damage caused by hydrogeological and environmental geological disasters to the ecological environment and achieving sustainable ecological development.
