【摘要】 运用综合信息推断基底构造格架。研究表明:地震带和地震点位于莫霍面陡度带、低速层陡度带、重力线型构造、重力环型构造以及重力线型构造交汇处;地震带和地震点与地下水、温泉、放射性铀矿的分布规律一致,同受基底构造格架控制;我国水系与线型构造关系密切,湖泊位于线型构造交汇处。利用上述研究成果开展地震区划,圈定安全区和安全岛,为我国的城市建设和重大工程建设的合理布局提供科学依据。更多还原

【Abstract】 Basement tectonic framework can be deduced by utilizing comprehensive information.Research result in the paper indicates seismic belts and seismic points locate at Moho steepness belt,low velocity layer steepness belt,gravity linear structure,gravity ring structure,or the intersection point of gravity linear structures,and their distributions are also consistent with the distribution of ground water,hot spring and radioactive uranium mines;river system in the country relates closely to the linear structure;while lakes locate at the intersection points of these linear structures.With these reles,the seismic can be zoned to delineate safe area and safety island,thus provides a strong scientific basis for our country’s urban constructions and suitable distributions of major construction projects.更多还原
