摘要
辽宁省地质灾害是内外动力地质作用及人为地质作用的结果。本文从宏观上阐述了辽宁地质灾害发生、发展的地质环境背景、地形地貌背景,水文气象背景以及生态环境对地质灾害的制约作用。按照地质灾害的成因提出了地质灾害的八种主要类型及发育分布规律,并指出其发展趋势。提出了地质灾害防治的技术对策。
Endogenic and exogenic geological process as well as cultural geological process resulted geological hazards in Liaoning Province. A discussion on geological environment background for origin and development of geological hazards in Liaoning Province, topog- raphy and geomorphology, hydrographic climatology and ecological environment controls on geological hazards are generally studied in this paper. Eight main types of geological hazards, their distribution feature for development and evolution trend are proposed. Finally, the technical countermeasures for preventing geological hazards are recommended.
