%X In the last few decades,due to rapid economic development and urbanization,potentially harmful contamination of soils and vegetation has become increasingly serious in the world.Due to their persistent nature and long biological half-lives,contaminants can accumulate in the food chain.High contents of these contaminants are known to be very toxic to various biota.Hence,there is an increasing need to investigate the plant stress using the remote sensing method.Firstly,this paper pointed out the major factors affecting the spectral features of plants.These factors include chlorophyll concentration,cell structure and water content in leaves.The spectral variation of the stressed plants was analyzed.Secondly,the major indicators (vegetation index and red edge) by which to investigate plant stress using the remote sensing method were introduced.We also discussed the two applications of the remote sensing method for investigating plant stress.One is for heavy metal and the other is for oil contamination.We showed that appropriate vegetation index and the accurate position of red edge are the key to investigate vegetation stress.In the end,we showed the prospect of investigating vegetation stress using the remote sensing method for the future studies.
