本文综述了若干美国地震活动区城市地质研究成果,这些成果应用地学资料基础,紧密结合和服务于城市的决策、规划与建设,从经济角度评价各种起因于地质灾害的破坏和损失费用,从而为土地利用的规划与决策建立了土地利用能力的定量性分析法,说明美国城市地质研究已更趋务实。 This paper summarizes the results of several studies on urban geology in the seismic zones of the United States. These achievements apply the geo-data basis to closely integrate and serve urban decision-making, planning and construction and economically evaluate the costs of various damage and loss caused by geological hazards. A quantitative analysis of land use capacity has been established for land use planning and decision-making, which shows that urban geology in the United States has become more pragmatic.
