【摘要】：石油和石油產(chǎn)品的泄漏可造成嚴(yán)重的土壤污染,傳統(tǒng)的土壤石油烴污染監(jiān)測方法存在耗時長、便攜性差等問題,難以滿足大面積診斷土壤污染區(qū)域和數(shù)字化土壤制圖的需求�？梢�-近紅外光譜技術(shù)具有快速、便捷、低成本和無污染等優(yōu)勢,是土壤信息快速獲取最有潛力的手段,也是未來研究發(fā)展的趨勢。該技術(shù)目前在監(jiān)測土壤性質(zhì)領(lǐng)域已經(jīng)取得了一定的成果,但在監(jiān)測土壤石油烴污染方面,國內(nèi)外的研究仍然處于起步階段,石油烴含量反演模型的實際應(yīng)用仍然是難點,而且針對現(xiàn)有的成果很少有人對其進行總結(jié)。文章探討了可見-近紅外光譜監(jiān)測土壤石油烴污染的可行性,并歸納和總結(jié)了污染土壤的光譜敏感波段、預(yù)測模型和光譜數(shù)據(jù)庫三個方面近幾年最新的研究進展,分析了目前研究成果中存在的不足,并對未來的研究方向進行了展望,指出今后應(yīng)加強多種類型土壤石油烴混合物樣本、通用的石油烴預(yù)測模型、野外光譜測量實驗和成像光譜技術(shù)等四方面研究,以期為后續(xù)進行土壤石油烴污染的深入研究提供借鑒。
[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.
