تحلیل فضایی ـ زمانی مدیریت مخاطرات آنتروپوژنیکی معادن در ایران

The appearance of Hazards in human life is affected by natural and human forces. So far, human beings were the most powerful stimulant to create these hazards and to intensify them. The negative role of human beings in environment is caused by factors like lack of knowledge, weak reaction, technology lack, aggressive ideologies and competition; in social system, however, human behavioral engineering especially in dealing with nature is totally affected by management system. One of the common human behaviors which place in economic system framework is extraction and exploitation of Mines that has many consequences for ecosystem. In fact, Mines are the result of human beings reactions in dealing with nature which their activity ranges are increasing. According to micro-scale to macro-scale in economics, economic life of a country like Iran is based on its huge natural/mineral recourses.      On the other hand, environmental consequences of exploiting Mines in this country are numerous and varied. In this study, we tried to present a spatial-temporal analysis and explanation about environmental hazards phenomena in the case of exploiting Mines of the country caused by human beings with the title of "anthropogenic hazards in Mines” that is totally a result of its respective management system. In terms of its objectives, this study is a practical research and it is a descriptive-analytic one. For data collecting, we reviewed the existing literature and surveyed the data base in Statistical Center of Iran. These data are extracted from 2009 census and 2013 census (because of limited statistical domain) which belong to all the provinces of the country. To perform the analysis, these data are collected based on 5 indices and 16 sub-indices and after completing data base, percentage distribution graphs for Mines  and environmental activities in the provinces (in 5 total framework) has been drawn by using GEO DaTM software. Following that, by using a multi-criteria decision making method (COPPARS) all the regions are ranked according to the level of their environmental hazards in exploiting Mines. Finally, to illustrate the spatial pattern and method of hazards in Mines in the country on the studied period of time, based on COPRAS method, the calculated standard deviation ellipse was drawn in GIS which is according to 2009 and 2013 data.       Studying the increasing number of Mines  which are exploiting in the provinces of the country during 2009-2013 confirm that most of the provinces had experienced a positive growth during this period of time and among these areas Ardabil, Alborz, Ilam, Bushehr, Tehran, Kurdestan, Qazvin, Fars, Luristan and Hamadan provinces had experienced a negative growth and we can mention to other economic activities reinforcement as the reason of this negative growth such as services in Mines  section rather than activities in this section, spatial location and the influence of border line or ignorance of planning system. On the whole we can conclude that in economic system of the country, there is a constant attention to Mines and expansion of their exploitation in the area.      According to the findings of this study, we can conclude that in spite of the existence of Mines  which are extracting in all around the country and the expansion of exploitation of these resources in these regions, required attention and consideration is not paid to decrease or modify destructive effects on environment in the case of Mines  which are operating in the country, on the contrary indices such as investment and increasing the value of investment had decreased, and by considering the inflation in country, it can be said that economic attention to Mines  management in the country to reinforce the basis of environmental compatible Mines  is insignificant and declining. So it is not out of question that exploitation of these Mines in this country is an effective and intensifying factor to create and intensify other human-made and natural hazards.      In regional point of view, management activities which modify negative and destructive effects of exploiting this country's Mines  (maybe in a small scale) are done by ignorance to regions that have predetermined hazards and it seems that other factors are used to conduct and strategize the environmental compatible management engineering in exploiting of the country's Mines  not the systematic management factors; for example, according to Iran's Environmental Protection Organization (EPO) statement, Isfahan, Fars Yazd, Khuzestan, Bushehr and Hormozgan provinces are dealing with the highest level of environmental hazards (IRNA, 2015), while these provinces have the most hazardous Mines  and they are located in the limited area of anthropogenic hazards of Mines  or they are close to regions that have maximum Mines ' hazards. In industrial provinces as Isfahan which are dealing with water scarcity and environmental pollution too, "anthropogenic hazards of exploiting Mines  which are the result of management" could create hazards like different kinds of water and air pollutions and they also enforce spatial environmental hazards.     Finally, according to spatial-locational movements or changes of place, related to anthropogenic hazards of exploiting Mines in Iran, it can be said that the dominant approach on economic system of region which is related to Mines is proceeding fast to important population centers of the country and similar problematic ecosystems which may cause the appearance of hazardous crisis in some parts of the country.
