Abstract: As the issue of environmental pollution is increasingly serious, relevant studies are moving further and deeper, and more and more high-tech approaches are applied. Synchrotron radiation is a special electromagnetic radiation, which is the tangent radiation induced by circular or snakelike moving electron with a speed close to light. This radiation has high brightness and superior performance, and can be used in a broad energy spectrum. This paper reviewed theapplications of synchrotron radiation in monitoring environmental pollution (water body, atmosphere, and polar region) and in the ecotoxicology of organic pollutants and heavy metals, and discussed the prospects of the applications of this technology in environmental science.

Key words: Picea koraiensis-Abies nephrolepis forest, population structure, gap maker, point pattern analysis, interspecific association.
