土壤漏油含量光譜預測實驗研究與分析
[Abstract]:Aiming at the practical problems of oil spill pollution detection, analysis and content prediction, the common soil, diesel oil, oil and oil-soil mixture in Guanzhong Plain were used as the research objects. The experiments of soil spectral characteristics with different oil pollution and different pollution degree were designed. The spectral index was obtained by spectral analysis, and the spectral characteristics and differences of the oil-soil mixture with the same leakage content and the same oil content with the same oil content were measured and analyzed. Based on the analysis results, a spectral prediction model of soil diesel leakage content based on reflection characteristics was established. The results showed that: (1) the reflectivity of the soil with the same leakage content of different oil species was lower than that of the oil leakage soil, and the double absorption valley was found in both the oil and diesel oil leakage soils near 1 740 and 2 328nm. The spectral absorption depth and spectral absorption index of diesel-leaking soil at each point of absorption valley are lower than those of the soil with the same oil content. (2) the correlation coefficient r of the spectral prediction model for the leakage content of soil diesel oil is established. The value reaches 0.854, which indicates that the model has strong stability. The root-mean-square error (RMSE) of the evaluation model was 0.016, which proved that the model had good prediction ability and could be used to predict soil diesel leakage effectively.
