【摘要】：石油和石油产品的泄漏可造成严重的土壤污染,传统的土壤石油烃污染监测方法存在耗时长、便携性差等问题,难以满足大面积诊断土壤污染区域和数字化土壤制图的需求。可见-近红外光谱技术具有快速、便捷、低成本和无污染等优势,是土壤信息快速获取最有潜力的手段,也是未来研究发展的趋势。该技术目前在监测土壤性质领域已经取得了一定的成果,但在监测土壤石油烃污染方面,国内外的研究仍然处于起步阶段,石油烃含量反演模型的实际应用仍然是难点,而且针对现有的成果很少有人对其进行总结。文章探讨了可见-近红外光谱监测土壤石油烃污染的可行性,并归纳和总结了污染土壤的光谱敏感波段、预测模型和光谱数据库三个方面近几年最新的研究进展,分析了目前研究成果中存在的不足,并对未来的研究方向进行了展望,指出今后应加强多种类型土壤石油烃混合物样本、通用的石油烃预测模型、野外光谱测量实验和成像光谱技术等四方面研究,以期为后续进行土壤石油烃污染的深入研究提供借鉴。
[Abstract]:The leakage of petroleum and petroleum products can cause serious soil pollution. The traditional monitoring methods of soil petroleum hydrocarbon pollution have the problems of long time consuming and poor portability. It is difficult to meet the needs of diagnosing soil pollution areas in large areas and digitizing soil mapping. Visible-near infrared spectroscopy has the advantages of fast, convenient, low cost and no pollution, so it is the most potential means to obtain soil information quickly. It is also the trend of future research and development. This technology has made some achievements in the field of monitoring soil properties, but in monitoring soil petroleum hydrocarbon pollution, the research at home and abroad is still in its infancy. The practical application of the petroleum hydrocarbon content inversion model is still difficult, and few people summarize the existing results. This paper discusses the feasibility of monitoring soil petroleum hydrocarbon pollution by visible near infrared spectroscopy (NIR). The recent advances in spectral sensitive band, prediction model and spectral database of contaminated soil are summarized. The shortcomings of the present research results are analyzed, and the future research directions are prospected. It is pointed out that four aspects should be strengthened in the future, such as the samples of various types of soil petroleum hydrocarbon mixtures, the general petroleum hydrocarbon prediction model, the field spectral measurement experiment and the imaging spectral technique. In order to provide reference for the further study of soil petroleum hydrocarbon pollution.
