【摘要】：海洋溢油与烃渗漏是资源与环境遥感关注的重要方向之一。光学遥感在该领域的理论与应用研究表明:(1)光学遥感探测的分类目标已经明确,即溢油污染形成的海面油膜、黑色浮油与油水混合物,海底烃渗漏形成的海面油膜与近海表大气碳氢化合物气体异常;(2)这些目标对入射光具有不同的光学作用过程(如反射、吸收、散射、干涉等),会产生不同的光学响应特征,是光学遥感识别、分类与定量估算的理论基础;(3)在实际应用中,目标介质面(不同类型、折射率与粗糙度的油面与海面)的菲涅尔反射差异,有利于目标探测的同时,也给目标识别分类与定量估算带来诸多不确定性影响。光学遥感技术在本领域的应用特点与优势逐渐清晰,但依然面临巨大的挑战,今后的研究趋势也主要集中于以下几个方面:光学传感器的可探测性,典型目标的光学响应特征,定量遥感模型与参数查找表,目标的光谱与空间尺度响应,实地测量等。随着研究的深入,光学遥感技术必能以新的视角为海洋溢油与烃渗漏目标的实时监测、识别分类与定量评估提供更好的解决方案。
[Abstract]:Marine oil spill and hydrocarbon leakage is one of the important direction of remote sensing on resources and environment. In the field of optical remote sensing theory and application research shows that: (1) the classification of target optical remote sensing has made it clear that the oil spill pollution formation of oil slick, black oil and oil-water mixture, the formation of abnormal seabed hydrocarbon seepage oil spills and sea surface atmospheric hydrocarbon gas; (2) the target light has different optical processes of incident (such as reflection, absorption, scattering, interference, etc.) will produce different optical response characteristics of optical remote sensing identification, classification and theoretical basis for quantitative estimation; (3) in the actual in the application, the target medium (refractive index and surface roughness of the sea surface and the oil of different types, the Finel reflection difference), is conducive to the target detection at the same time, but also to the target recognition and classification and quantitative estimation brings many uncertainties. The optical effect. The application characteristics and advantages of sensing technology in this field gradually clear, but still faces enormous challenges and future research trends are mainly focused on the following aspects: detection of optical sensor, the typical target characteristics of optical response, quantitative remote sensing model and parameter lookup table, spatial and spectral dimensions of the target response, field measurement. With further research, optical remote sensing technology will be in a new perspective for the real-time monitoring of marine oil spill and hydrocarbon leakage targets, provide a better solution for classification and quantitative evaluation.
