Morpho-sedimentological and vegetational characterization of Grande beach at São Francisco do Sul Island (Santa Catarina, Brazil)

A multidisciplinary study based on several digital (geology, lithology, shoreline evolution, photo-interpretation of aerial and ortho-photographs) and field (topographic and vegetational surveys, grain-size analysis) datasets prompted new insights to a better definition of the processes in action at the Grande beach at São Francisco do Sul Island (Santa Catarina, Brazil). The resulting data enabled us to produce a multi-thematic map at 1:50,000 scale that might be useful in assisting decision-makers to manage the coastal system, taking into account involved factors at once and not separately. In addition, the map may be implemented and integrated with new information, since the database is provided in geographical information system. The results confirmed the importance of addressing coastal systems with a multi-faceted approach that can be applied everywhere, not only in settings similar to São Francisco do Sul Island.

本项多学科研究依托多组数字数据集与野外数据集展开，其中数字数据集涵盖地质学、岩性学、岸线演化、航空与正射影像（ortho-photographs）解译，野外数据集则包括地形与植被调查、粒度分析；该研究为巴西圣卡塔琳娜州圣弗朗西斯科杜苏尔岛格兰德海滩的现行动力过程提供了全新认知，助力更精准地界定这些过程。依托所得数据，我们制作了比例尺为1:50000的多专题地图，该地图可辅助决策者统筹管理海岸系统，能够同时考量所有相关影响因素，而非割裂地单独分析各因素。此外，由于本数据集以地理信息系统（Geographical Information System）格式存储，该地图可随时进行更新与信息集成。本研究结果证实，采用多维度方法开展海岸系统研究具有重要价值，该方法可推广至全球任意区域，而非仅适用于与圣弗朗西斯科杜苏尔岛相似的海岸环境。
