摘　　要：本文对泉州湾地区建设用地的地质条件进行分析,确定了泉州市环泉州湾地区建设用地主要存在的潜在地质灾害为地震、崩塌、滑坡和危岩体。根据层次分析理论,建立地质灾害危险性评价的层次分析模型,将泉州湾地区建设用地按危险性程度分为高危险、中危险、低危险、安全四个等级。评价结果:泉州湾大部分地区相对安全,适宜作为建设用地进行工程建设;高危险和中危险区主要位于西部山地丘陵地区,且处于断裂带附近,不适合进行开发建设;东部沿海也存在中危险区域,因此不宜再进行过度的工程建设。This paper analyses the Geological conditions in the area of Quanzhou bay and ensures the major and potential geological disasters of the construction land in Quanzhou bay area which are Earthquakes, col-lapse, landslide and dangerous rock mass. According to the theory of Analytic Hierarchy Process, we set up the analytic hierarchy process model of geological disaster risk assessment. And according to the risk degree of the construction, land in Quanzhou bay area can be divided into four levels: high risk, medium risk, low risk and the safe. By the evaluation results, most areas of the Quanzhou bay are relatively safe and are suit-able for engineering construction as the construction land. High risk area and medium risk area which are not suitable for development and construction are mainly in the western mountainous hilly region and near the fault zone. Danger also exists in the eastern coastal areas, it is not appropriate to conduct excessive construc-tion.
