摘要
地形地质条件是形成山洪灾害的基本因素,作为山洪灾害防治区划研究的组成部分,山洪灾害地形地质区划是一项重要的基础性专业区划。分析了山洪灾害易发程度与地貌、地层岩性、地质构造等地形地质条件的相互关系,提出了区划原则和技术路线,介绍了进行全国山洪灾害防治地形地质区划的基本方法、步骤及其相关技术。
Landform and geological conditions are the basic factors for the formation of mountain flood disasters. As a part of studies of mountain flood zoning, landform and geological zoning of mountain flood prevention is fundamental. On the basis of analyzing the relationship between liabilities of mountain flood and landform, lithologic character of stratum, geological structure, the principle of zoning and technical route are presented. The method, procedure and technology of landform and geological zoning of mountain flood prevention of China are introduced.
