Abstract: Environmental pollution and its solicitation in ecological problems of old industrial and mining areas have become a worldwide technological puzzle restricting sustainable economic and social development.But,the definition and category of old industrial and mining areas is still disputed as an important concept.In this paper,the concept of old industrial and mining area was discussed in theory,and,proceeded with analyzing the complexity of current situation and environmental pollution problems of old industrial and mining areas in China,more keystone attention was paid to the secondary pollution problems from old industrial and mining areas as an important frontier of science.On the basis of expounding the complexity and characters of environmental pollution in old industrial and mining areas,it was suggested that as two key scientific problems in environmental sciences and ecology,the formation mechanisms and control technology of secondary pollution in old industrial and mining areas and the responses of new-type diseases to environmental pollution based on molecular ecotoxicology should be systematically studied on the national scale,and be an important component of environmental protection strategy in China in the future.
