摘　　要：化探背景与异常划分涉及系统误差和不同地质体的背景差异，是地球化学找矿中至关重要的内容，直接影响能否正确提取找矿信息和化探找矿效果。背景与异常划分方法可分成估值和模式识别两大类，无论使用何种方法。The systematic error and background differentiation of different geological bodies are concerned in discrimination of background from anomaly, which is an important issue in geochemical prospecting and affects the correct extraction of geochemical information and prospecting effectiveness. The methods of discrimination of anomaly from background are divided into estimating methods and model recognition methods. It is necessary to transform the original data to be consistent with geological regularities.
