第一节防灾抗灾基本方针一、地质灾害基本类型和主要特征综合本区主要地质灾害,可归结为两大类。其一,岩石圈灾害,主要是地震造成的直接灾害和间接灾害;其次是崩塌、滑坡、泥石流和特殊岩土灾害等。其二,水圈灾害,包括陆地水灾害和海洋水灾害两个方面。陆地水灾害除干旱、洪涝外,最主要的是水资源危机和由于高强度开发水资源所引起的地面沉降、地面塌陷、海水入侵等灾害。海洋水灾害主要是风暴潮灾害,其次是海岸侵蚀等。
The first section of the basic principles of disaster prevention and disaster prevention First, the basic types of geological disasters and the main features Comprehensive The main geological disasters can be attributed to two categories. First, the lithospheric disasters are mainly direct and indirect disasters caused by earthquakes, followed by landslides, landslides, debris flows and special geotechnical hazards. Second, the water ring disasters, including land water disasters and marine water disasters in two aspects. In addition to drought and floods, land-based water disasters are mainly caused by water resources crisis and land subsidence, ground subsidence and seawater intrusion caused by high-intensity development of water resources. Ocean water disasters are mainly storm surge disasters, followed by coastal erosion.
