| Today, Industry and traffic can be a major contributor to the air pollution in the cities. The traditional methods for the study of air pollution are based on chemical measurements and analysis which requires time, labor along with relatively high costs. Study of spectral behavior of Plants affected by environmental stresses is one of the non-destructive methods in remote sensing science. The visible and near-infrared spectroscopy of plants technique, since it’s quick, easy to use and precise, is widely used to predict the biochemical components of plants and their changes. The aim of this study is to study the spectral reflectance behavior of leaves exposed to traffic pollution of a part of Imam Khomeini highway, Isfahan-Iran. Spectral characteristics of the leaf surface of infected species including ash, cypress and elm using spectral indices sensitive to stress and chlorophyll were studied. The results of artificial neural network to distinguish the control and polluted species using spectral indices (PRI, NDVI, Gitelson and …) shows the accuracy of 73.4%. The PLS regression model was conducted simultaneously for three species in polluted and control modes and it does not have any acceptable results. In addition, the model was conducted separately for each species; it showed acceptable results for ash trees in polluted and control modes. |
