摘要： 将地学信息图谱的方法引入到南极无冰区生态环境的研究中，以菲尔德斯半岛作为研究区，采用矢—栅混合数据模型确定图谱单元，通过数据挖掘对环境诸要素信息进行分类提取、分级和归纳概括，构建了地形地貌、土壤、植被、人类活动等系列单要素专题信息图谱模型和环境景观综合信息图谱模型，对图谱模型进行了空间三维可视化设计，定量化、定位化、谱系化地揭示了区域生态环境及其要素的空间形态结构和空间相关特征，为南极无冰区生态环境的深入研究提供新的技术途径和科学依据。

Abstract: Geo-information TuPu is introduced to the eco-environment study of ice-free area in Antarctica. The article has taken the Fildes Peninsula as an example for case study and determined the TuPu unit by using of vector-grid mixed data model. The classified information of the environmental elements was effectively extracted and generalized by means of data mining. The paper built series of single-factor thematic information TuPu model and the landscape pattern comprehensive information TuPu model. The thematic information TuPu includes topography, soil, vegetation and human activities. The three-dimensional visualization of the genealogical models is designed. The spatial morphology and the spatial correlation of the regional eco-environment is revealed quantitatively. All these efforts may provide a new technical approach and scientific basis for the in-depth study of Antarctic eco-environment.
