摘要: 重金属污染物原位监测是对废弃金属尾矿库重金属污染治理的基础，由于缺乏基础监测数据，基础数据采集工作量巨大。采用对应分析法建立某尾矿库的土壤样本和污染物之间的联系，以达到优化监测点和监测因子的目的。将监测点和监测因子反映到同一因子轴的图形上，能清晰直观地表述监测点和污染物间的内在联系和分布特征；确定主监测点和主监测指标，在保证监测数据的典型性和代表性的前提下，减少监测点数量，达到优化布点；利用污染物之间的相关性，减少监测指标数量，提高采集数据的效用。Abstract: Heavy metal pollution in-situ monitoring is the foundation of pollution treatment. Due to the lack of basic monitoring data， the workload of basic data collection is huge. In order to optimize monitoring points and monitoring factors， the relationships between pollutants and soil sample were established by using correspondence analysis method. The intrinsic link between pollutants and monitoring points and distribution characteristics can be clearly expressed if monitoring points and monitoring factors are put on the same axis in the graphic. To determine the main monitoring points and the main monitoring factors， the number of monitoring points can reduce and optimize under the premise of ensuring the typical and representative of monitoring data. Using the correlation of pollutants can reduce the number of monitoring factors and improve the effectiveness of data collection.
