Site selection for the research stations is an important and necessary issue for Antarctic expedition, affecting both scientific investigation and service life of the stations.This study was conducted to identify suitable sites for Antarctic research stations, using geographical information systems (GIS) combined with fuzzy analytical hierarchy process (FAHP).Due to the extraordinary nature of Antarctic environment, the selection of the optimal site requires consideration of multiple evaluation criteria.Based on actual conditions of the study area, fifteen criteria, grouped into four main criteria: scientific interest, environment, accessibility and topography, were considered and calculated weights using the FAHP in GIS capabilities.Fuzzy hierarchy models were build for solving the station site selection problems.All maps are scored from 1 (not suitable) to 3 (most suitable) using spatial information technologies.The raster-GIS models were developed by aggregating the graded maps based on the criteria weights.Most suitable sites were generated from the model and the candidate site for Chinese 4th Antarctic research station was suggested.This work offers a siting methodology and provides essential support for decision-makers in the assessment of Antarctic station building problems for China as well as other countries.
