近十余年来,随着世界上科学技术的飞跃发展,工农业建设的广度和深度亦与日俱增。人类经济活动已成为一种强大的“地质营力”,不断地改造岩石圈表部的地质环境,对人类的生产和生活产生了利害相关的巨大影响。因此,对国民经济规划地区的环境评价和开发以及环境保护的工程地质研究已日益为人们所重视。从这次第四届国际工程地质大会所征集的三百 In the past decade or so, with the rapid development of science and technology in the world, the breadth and depth of industrial and agricultural construction have also increased. The economic activities of mankind have become a kind of powerful “geotagging force”, which continuously reforms the geo-environment of the lithospheric surface and has a tremendous impact on human production and life. Therefore, it has been paid more and more attention to the environmental assessment and development of the national economic planning area and the engineering geological research of environmental protection.
