摘　　要：本文介绍了趋势面分析法的数学方法和原理,以山西省怀仁市地质灾害易发性分区评估为例,根据山西省怀仁市地质灾害特点,在地理信息系统基础上运用趋势面分析法,对山西省怀仁市地质灾害易发分区进行了评估。研究表明,结果与实际情况相一致。因此说明该方法能够为解决地质灾害易发区的划分提供新的途径。This study presented the mathematical principle of trend surface analysis method.Based on the features of geo-hazards in Huairen,Shanxi Province,the susceptibility-zoning assessment is made by using trend surface analysis method in GIS program.The results show the consistency with the actual investigation of the geological survey information,which proves that trend surface analysis method is applicable for susceptibility-zoning assessment and can provide a new theoretical approach for geo-hazard zoning.
