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。Abstract: 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 Ueographical 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.
