Yibin City Environmental Geology Evaluation

With the development of global urbanization, the effect of geological environmental factors at the development of the city also increasing obviously. It becomes the actual problem about the city development nowadays, so it becomes a new research of city geology study how evaluate the city's environmental geology.This article takes Yibin City for example, based on the data which came from the geology, mine, hydrology , the physical geography , the economy and the development programming of Yibin all-around., This article has found the geological environmental condition and main problems about city programming, construction and development, which by the way of the data exploiture and investigation on the spot. It also made use of the theories and methods of the city environmental geology, the environmental geochemistry and the city ecology etc. At the above-mentioned elements, I carried the homologous evaluation which include The Analytic Hierarchy Process on the city environment geology of Yibin City I divided the city environment geology into the city geology environment condition foundation evaluation, the city geology disaster risk evaluation and city geochemistry friability evaluate. New exploration on evaluation method and the evaluation systems in the city environmental geology was done.The geological environment of Yibin City is good as a whole. The area of good geological environment arrives at 74.88%, and the area of bad geological environment only accounts for 1.16%, so it adapts to human habitation and development of city. At the same time, it affects city constructing and development that the city geology disaster, ill geological bodies and acid rain etc. This article, combining the programming of Yibin City, put forward the homologous prevent and cure district and measure which aim at the main environment geological problem in the research area. This article offered scientific and accurate hereunder in geological environment to improve and adjust the city ecosystem of Yibin City, and to table a proposal to the development programming of city society, economy.
