摘　　要：为了评价并推进"北京一号"小卫星在我国矿产资源调查领域中的应用,以新疆哈密黄山铜镍多金属成矿带为试验区,在深入分析岩石及其影像光谱特征的基础上,针对小卫星多光谱数据,采取几种信息增强方法对构造和矿化蚀变信息进行提取,结果证明了所用方法对"北京一号"小卫星褐铁矿和绿泥石类等矿化蚀变异常信息提取的可行性。In order to evaluate and promote the application of small satellite Beijing - 1 in mineral resources exploration, the authors used this satellite as data source to do some information extraction study of the remote sensing mineralizing anomalyin the Huangshan copper- nickel ore belt. The lab and image spectra of various rocks were analyzed, and then the structural and mineralizing technique. The results show that it alteration information was extracted by using an effective image processing is feasible to extract alteration anomaly of iron - bearing minerals such as limonite and chlorite with Beijing- 1.
