Rising and Development of Environmental Sedimentology

Environmental sedimentology emerged as the times require when human beings are facing with some key issues of ecological destroy, environment pollution, disaster and global changes and development of environmental science and sedimentology. The development of environmental sedimentology underwent two stages and has been given more and wider attentions since mid-1990's. The concept and study target of environmental sedimentology are defined in this paper. The study content includes not only environmental problem in sedimentology study but also sedimentary one in environmental science study, and 4 main study directions are original environmental sedimentology, contamination environmental sedimentology, entironment sedimentology and global change environmental sedimentology. Environmental sedimentology, studying environment and disaster, must be important for solution of environment contamination, ecological destroy, geologic disaster and global climate change, and are becoming one of important development directions of sedimentology.
