| 摘 要： | 本文采用三种定量的分析方法,根据辽宁省内的地震活动水平,活动断裂线密度、地壳厚度变化梯度、断裂线密度、布格重力异常变化梯度和地壳形变速率六个定量化评定因素,对辽宁省的地震危险区进行了判别。结果表明,这三种方法所评定的结果有较好的一致性,其结果可以在辽宁省震害预测等工作中加以应用。

| Abstract: | Three quantitative analysis methods are adopted in this paper. According to six quanti-tative evluating factors: seismicity, line density of active fault, line density of general fault,gradient of crust thickness; Bouger gravity anomaly and gradient of crust deformation, theseismic risk regions in Liaoning Province are determined. The results of three methods showthat they have better consistency, and can be widely used in some practice works estimatingearthquake hazard of Liaoning Province. |
