| 摘 要： | 分析研究珠江三角洲地区的新构造运动、活动断裂、地壳厚度、地壳沉降、地热分布、地震活动等资料，其呈现出比较明显的空间分异。认为珠江三角洲区域稳定性划分为稳定区和次稳定区，区域地壳稳定性活动程度中等，次稳定区主体在地质构造区划上属于珠江三角洲断陷区及三角洲沿海区域，次稳定区范围之外的相对隆起地带为稳定区。

| Abstract: | Analysis of the characteristics of neotectonic movement, active faults, crust thickness, crust sedimentation rate, geothermal distribution and seismicity in Pearl River Delta, shows their obvious spatial difference. It is suggested that Pearl River Delta is mainly medium-stable zone in crust stability; and that in this zone, the crust stability can be divided into the stable area and secondary stable area . The principal part of secondary stable area is belong to Pearl River Delta fault-depression and the coast of Pearl River Delta, the stable area is uplift zone out site of secondary stable area. |
