目前 ,全球 5 0 %以上的人口生活在地球表面不到 1%的面积上 ,城市化是当今全球发展的重要趋势。人类活动是生物圈中最重要的活动之一。半个世纪以来 ,人类活动的重要特征就是人口的城市化。作为传统地球物理学的一个新的发展领域 ,城市地球物理学就应运而生了。城市面临的环境问题和灾害减轻问题 ,都要求发展城市地下三维地图的科学基础。地下三维地图既是城市地球物理学的核心科学问题 ,也是我国地球物理学家面临的挑战和机遇。城市地球物理是地球物理学新的发展领域。
At present, over 50% of the world's population lives on less than 1% of the Earth's surface. Urbanization is an important trend in global development today. Human activity is one of the most important activities in the biosphere. For half a century, an important feature of human activity is the urbanization of the population. As a new development of traditional geophysics, urban geophysics came into being. The environmental issues and disaster mitigation that cities face require the development of the scientific basis for urban underground three-dimensional maps. Underground three-dimensional map is not only the core of urban geophysics science issues, but also our country's geophysicists are facing the challenges and opportunities. Urban geophysics is a new development of geophysics.
