摘要
森林沼泽是我国重要的景观类型,自2000年以来采用新的方法技术重新实施了森林沼泽景观区域地球化学调查,截至2011年已完成调查面积29万km2,采集水系沉积物样品73 000余件,分析测试39种元素或氧化物,积累了十分丰富的地球化学信息。针对这些十分宝贵的资料,笔者采用金维地学信息处理研究应用系统(GeoIPAS)计算了数据平均值、中位值、标准离差、数值范围等系列参数。统计的各种地球化学参数值反映了该景观区的地球化学区域性特征,为进一步研究地球化学分布规律,发现地球化学异常,开展矿产资源远景评价提供了重要的基础性参考依据。
Forest swamp is an important landscape type in China. New technology has been used to re-implement the regional geochem- ical survey of the forest swamp landscape since 2000. An area of 290 000 km2 had been completed by the end of 2011. 73 000 pieces of stream sediment samples were collected and analyzed for 39 elements or oxides. Valuable geochemical information was accumulated in this study. Series of geochemical parameters such as the average, median, standard deviation, and range of elements content were calculated by JinWei software of geoscienee information processing application systems （GeolPAS）. The results provide some important reference information concerning the regional geochemical characteristics of the landscape area and geochemical anomalies for further e- valuation of mineral resources in such landscape areas of China.
