3、 human health. So we need acquire the information of soil heavy metal pollution quickly and effectively in order to realize the principle that the earlier we find it, the earlier we curb it. This paper summarized the traditional and new soil heavy metal detecting and monitoring methods at home and a
4、broad in recent years and analyzed their theories, characteristics and service condition,and contrasted the advantages and disadvantages of different methods. Then it pointed out that we can use the surficial or aerospace hyper spectral remote sensing to acquire the spectroscopic data of crops leaf
