Contaminated Land Repairing Analysis Of Urban Industrial Land In The Process Of Use Conversion

Land is an important part of ecological environment, one of the main resources that human's life depends on, and the storage of biological, physical, chemical's circles. City is the carrier of economy and social activities. The nature of urban land had significant changed from the regional background due to development of industry and human's activities. The threat of urban contaminated land to mankind is growing with industrial development and urbanization. Because there are very close and complicated relationships among the land, groundwater, wastes, industrial waste water, pesticides and various waste things. However, contaminated land has some characteristics like hidden, complexity, lag, which are often neglected. People paid attention on it until a lot of serious environmental incidents happened that caused by contaminated land.This paper analyzed the reasons for pollution of urban industrial land at first. Second, we discussed the necessity for the pollution control, related technologies and the innovation on financing and law. Then made an contaminated industrial land repairing project in Wuhan as an example, analyzed the characteristics of pesticides pollution of land, all possible treatment options and made a recommendation. Research and exploration of this paper had some reference value for solving the urban industrial land pollution problems and improving the climate of human's live.The first chapter introduced the research background and significance. first, I reviewed domestic and foreign researches. At last, I proposed the theme of the depth study. In chapterâ…¡, I made a clear definition about the urban industrial contaminated land, and from the theory of sustainable urban development, the theory of industrial structure adjustment, the theory of urban differential rent and the relationship between economic and environmental quality of the Kuznets curve explained why urban spatial structure changed and the necessity of urban industrial contaminated land repairing. In chapterâ…¢, the statuses were briefly introduced about urban industrial contaminated land. Then, I analyzed the advantages and disadvantages of some technologies which could be used in urban industrial contaminated land repairing. In chapterâ…£, I gave an example of urban industrial contaminated land repairing in Wuhan. Chapterâ…¤is the end of this paper. It summarized the last four chapters, and made an outlook.
