摘　　要：南极考察站选址问题关系南极考察站的安全、功能和运行效率。从科考兴趣、环境条件、后勤保障和地形条件四个方面构建南极考察站选址指标体系,将GIS和模糊层次分析法集成构建一种新的数学模型,用于确定南极考察站建立的适宜性区域,实现选址评价。在对已建南极考察站选址分析的基础上进行了模型验证,得到模型的准确度为98.89%,证明此模型具有较高的准确性和较好的适用性。Site selection for the Antarctic research stations affects safety, functionality, and operational efficiency of the stations. This study aims to build a criteria system and conduct the site selection aided by Geographical Information Systems and a Fuzzy Analytical Hierarchy Process. Fifteen criteria were proposed as multiple evaluation sub-criteria and were grouped into four main criteria： scientific interest, environment, accessibility and topography. Comparisons were made between the predicted suitable areas and locations of existing stations in Antarctica to show the fitness-for-use of allocation results. This work offers a comprehensive allocation methodology for decision-makers in the assessment of Antarctic station allocation problems.
