Analysis Of Socio-Economic Factors And Countermeasures On Territorial Ecosystem Geochemistry Of Jiangsu Province

"Territorial Ecological Geochemical Survey of Jiangsu Province"is a ministry-province cooperation item."Analysis of Socio-economic Factors and Countermeasures on Territorial Ecosystem Geochemistry of Jiangsu Province"(brief name"Countermeasures Analysis") is an important partial item of the cooperation item. On the basis of data on soil acidification and heavy metals pollution in Nanjing city and Suzhou city, and the change of soil fertility in Pei county and Tongshan county, the thesis investigates and scurvies and socio-economic development of these regions. The results show that regional socio-economic factors are the key factors in the process of regional ecosystem geochemistry system evolution. Regional social factors are an interaction with the regional ecosystem geochemistry factors and they affect mutually. Among them, the economic development, the population migration, the process of urbanization, industrial structure alternation and increasing ways of agriculture production and ways of lifestyle and other factors have important influence for characteristic of regional ecosystem geochemistry.Results show that economic development, the rapid urbanization and industrialization, the improvements of people's living quality play an important role in changing the soil quality.Industrial structure and urbanization are positively corrected to soil acidification and soil heavy metals pollutions. The change of industrial structure affects soil fertility by the agriculture proportion and way of agriculture production. The energy structure is positively corrected to soil acidification and heavy metal pollution. The usage of fertilizer and pesticide has the very strong relativity with the soil acidification, changes of soil felicity and soil heavy metals pollution. But agriculture planting structure soil heavy metals pollution have no direct relation. Improving the living quality contributes to the variety of consume structure and increasing the consumption of high-grade goods and electronics products, which has close relationship with the soil heavy metals pollution. Increasing the level of science and technology and quality of living, living habitual improvement have positive meaning by improvement of consumption of living energy on alleviation of soil acidification. The increment of fossil-fuel-type-motor vehicle is a major contribution factor in soil heavy metals pollution and soil acidification in living aspect.Soils are affected greatly by human activity and characterized by significantly anthropogenic enhancement of soil acidification, variations of soil fertility and heavy metals pollution. It will be helpful for us to protect and to remedy the ecosystem of soil better of we are learn the relation between the ecosystem geochemistry factors and the social economic factors. The aim of the thesis is to find the possible socio-economic factors that may influence the dynamic change in soil quality and their intrinsic relationship, to provide scientific basis for decision making to policy makers, using late soil survey data and corresponding socio-economic field survey data.The regional ecosystem geochemistry evolution is concomitant with human social development. Therefore, the starting point and the end of the thesis is that promoting the industrial structure, coordinating the process of urbanization, improving people's living habit and people's living quality, building a harmonious society, building a harmonious Jiangsu province.
