Soil is the important component of the geography environment. Today,soil heavy pollution has badly threaten to ecology environment and the human health, causing by human activity. Quickly obtain content of the soil heavy metals is the premise of managing the soil heavy metal pollution. And the development of the hyperspectral remote sensing technology offer a scientific means for quantitative measuring the content of the soil heavy metals. By summarizing the ways of quantitative inversion of soil heavy metals using hyperspectral remote and the influences to models affected by different spectral progresses, near the twenty years. At the same time, making a brief overview to the route of soil heavy metals inversion and the indirect inversion's correlative elements. Results show that inversion model decides the inversion accuracy, and the accuracy is affected by the preprogresses of spectrum. Last, discussed theshortages and trendency of the hyperspectral remote sensing used in soil heavy metals.
