【摘要】以IKONOS数据为信息源,对甘肃省白银铜矿区进行矿山开发占地信息提取实验研究.在经过预处理的图像上对研究区内的地物进行光谱采样,分析地物的光谱特征；并进一步建立合适的波段计算经验公式,用密度分割函数将矿山背景与占地信息区分开,消除了背景干扰；再根据光谱特征建立新的波段处理模型,对只有矿山占地的图像进行第二次密度分割,将矿山占地信息细分,通过目视解译为占地信息赋予属性.实地查证结果表明,利用计算机提取矿山占地信息能弥补目视解译的不足,不仅节省人力、物力、财力和时间,而且信息提取结果准确,具有实际应用的意义,对同类地区的矿山占地信息提取具有一定的参考价值.%In order to extract area information of the mine development based on processed IKONOS remote sensing data, the authors built 2 bands experience calculation formulas and 2 density segmentation functions after analyzing the spectral features of spectrum sampling data. First, density segmentation functions are used to extract the area information as a whole, which eliminates the background interference, and then the whole area information is divided into smaller pieces, which are then given specific types of meaning standing for the specific use of the area according to visual interpretation. Outdoor verification shows that using computer to extract information of area occupied by mine development can make up the deficiency of the
visual interpretation, such as saving human, material and financial resources and time. The extracted information is accurate and has practical significance, and is of reference values for extraction of information concerning land possessed by mines in similar areas.
