摘　　要：对安溪县剑斗岩溶地面塌陷的时空分布特征、影响因素、形成条件及形成机理进行探讨。结合当地的地质环境条件,建立各因子层次结构模型,应用层次分析法对可能发生塌陷的区域进行预测。研究结果表明安溪县剑斗岩溶地面塌陷主要与岩溶发育程度、覆盖层厚度及其岩性、地质构造、水力条件及人类工程活动等因素有关。Spatial and temporal distribution, affecting factors, forming conditions and mechanism of ground surface subsidence in Jiandou were analysed in order to provide scientific basis for ground surface substance prevention. With the local geographic conditions and by using T. L. Saaty＇s ＂1-9 degree＂ method, the factors construction hiberarchy model was established. The possible subsidence areas were predicted with the AHP method. The research results showed that the subsidence is related to karst development degree, the overlay thickness and its lithology, geological structure, hydraulic conditions and human engineering activities.
