| 摘 要： | 中国地处环太平洋构造带与地中海构造带交接部位，地质构造复杂，活动性较为强烈，各种内动力地质灾害比较严重，总体看来中国区域地壳稳定性相对较差。为了使区域地壳稳定性评价与分区获得定量化认识，更好地服务于经济建设和减灾防灾，本文在分析中国现今活动的主要构造体系与内动力地质灾害的分布规律的基础２进行区域地壳稳定性定量化评价待评区的划分；其次进行定量化评价指标的选定、取值、权重分配及评价标准的确定；最后运用

| Abstract: | China, as is located at the intersection of the circum-Pacific tectonic zone and the Mediterranean tectonic zone, has relatively strong active geological structures associated with various endogenic geological hazards. In this case it seems necessary to achieve a quantitative assessment and zonation of the regional crustal stability to better serve the economic construction and hazard reduction. The present paper attempts to present the methods to approach the problem in three steps based on the distribution of the main presently active structural systems and geological hazards as outlined in the text. |
