摘　　要： 针对地质灾害等级划分研究中存在的问题,在综合考虑农村小城镇地质灾害特点以及小城镇自身承载能力等情况的基础上,建立基于四元联系数的地质灾害灾度模型。将地质灾害大小划分为4级,即特大灾、大灾、中灾和小灾,并首次将四元联系数的原理引入灾度评估中,详细介绍了四元联系数的基本原理、评价过程等,并用于实例评价,得到了相应的计算评估结果。 In the light of the existing problems in the study of disaster degree classification of geological hazards,considering the characteristics of geological disasters and self-bear-capacity of rural small towns,we established disaster-degree model based on the four-element connection number.The geological disasters are divided into four degrees in the model,namely,extra-large disaster,large disaster,middle disaster and small disaster,and the basic principles of four-element connection number are introduced in the disaster degree evaluation.The principle and evaluation process of four-element connection number are presented and the model is applied in a practical case.
