摘　　要：在综合分析大量文献的基础上,归纳了高光谱技术在矿山次生矿物识别、重金属浓度反演、p H值定量估算、污染植被信息提取等方面的应用,总结了基于高光谱遥感提取有关氧化和脱水状态动态分析、气候变化追踪等信息的研究进展,展示了高光谱技术在矿山环境调查监测领域的广阔应用前景。研究表明,含铁硫化物及其氧化矿物标准光谱库的建立具有重大意义,推动了酸性矿山环境高光谱遥感研究;对矿山环境地质作用与光谱响应之间关系的认识逐渐深入,促进了高光谱地质应用模型的开发;高光谱数据蕴含着丰富的矿山环境地学信息,具备提取多方面重要信息的潜力。最后结合当前欧美发达国家开发高光谱小卫星的实际,指出今后矿山环境高光谱遥感研究将从矿物及矿物成分识别转向矿物形成时的物理化学性质反演、从短期调查向长期监测、从航空向航天、从单一矿山向成矿区带或大型矿集区转变。Based on an analysis of large quantities of literature,this paper describes briefly the application of hyperspectral technique to mine secondary mineral identification,reversion of heavy metal concentrations,p H prediction and contaminated vegetation detection,and then summarizes the research progress in such aspects as oxidation / hydration level and climate change through hyperspectral information extraction,thus showing widespread application prospect of hyperspectral technique in mine environmental survey. Some conclusions have been reached： the establishment of standard spectral database of Fe- bearing sulfide and its oxidized products is greatly helpful to hyperspectral research on acid mine environment,the understanding of geological process in mine environment and their spectral response helps to develop hyperspectral geological application model,and the hyperspectral data contain rich information about mine environment and has significant potential of extracting many kinds of information. According to the practice of developing hyperspectral satellite in developed countries such as countries in Europe and America,the authors point out that future hyperspectral research on mine environment will tend to experience the conversion from physical / chemical identification of minerals and their components to the physical / chemical property inversion during the formation of the minerals,from short term investigation to long term investigation,from aeroplane to hyperspectral sensor aboard on spaceship,and from single mines to large ore concentration areas.
