基于GIS的南极无冰区生态环境脆弱性评价
GIS-Based Assessment of Eco-environmental Vulnerability of Ice-Free Areas in Antarctica
-
摘要: 建立了南极无冰区生态环境脆弱性评价的GIS模型,基于此模型,实现了南极典型无冰区———菲尔德斯半岛生态环境脆弱性的定量化评价。从指标体系的建立、评价单元的确定、指标权重的确定以及综合评价等4个方面展开讨论。Abstract: The eco-environmental vulnerability of ice-free areas and its differences in the spatial distributions are analyzed.The strong capability of GIS such as data management,spatial analysis and 3D-visualization is explored to assist the assessment proceeds,and success in building up a feasible way of eco-environmental vulnerability quantity assessment.
