| 摘 要： | 珠江三角洲地质灾害种类的多样性与其所处的复杂地质环境和多变的气候条件密切相关。文章选用了地震活动、活动断裂、地壳升降运动、软土地基、地面塌陷以及冲、淤积等６个主要因素作为评价指标，并用模糊数学方法对珠江三角洲内１７个小区作了计算，结果表明该区大部分地区属于轻灾害区，只有滨海沿岸地区属于较重灾害区。

| Abstract: | Various types of geologic hazards in the Zhujiang River Delta relate to the complex geologic environment and climatic condition. In order to evaluate geologic hazards of the Zhujiang River Delta, the paper elects 6 main factors as evaluation characteristics, including earthquake activities, active faults, crustal elevation and subsidence movement,soft soil ground deformation, surface subsidence and siltation. According to the method of fuzzy mathematics, the paper calculates 17 small regions. The results demonstrate that the great majority belong to light-hazard regions, only the coastline zone belongs to the serious-hazard region. From now on, engineering construction must stay away from these regions and take effective measures to prevent hazards. |
