Abstract: Environmental geology is concerned with the study of the hazards resulting from human geologi-cal activities and geological environmentology is concerned with the study of the impacts of the natural en-vironment on the human beings.They are completely different disciplines.Ecoenvironmental geology applies the principles and knowledge of biology,environmentology,and geology to the solution of the problems caused by man's use and exploitation of the physical environment.It also involves studies of taxonomy ,e-cology,ecochemistry,environmental chemistry,sedimentology,Quaternary geology and geochemistry,as well as remobilization,enrichment and redeposition of elements caused by human geological activities.This branch of earth science is very important for the human life and health and concerns the sustainable eco-nomic development of the country and regions.The study of ecoenvironmental geology includes the fol-lowing content :(a)the loadability of ecoenvironmental geology,(b)monitoring,(c)early warning,(d)rehabilitation,(e)laboratory experiment ,and(f)computer simulation.
