The Research on the Assessment Module Based on the Environmental Long-term Hazards Caused by the Oil Medium

摘要

The oil pipeline is the aorta of the countries economic development and the principal pillar of economic development.But with the aging pipeline,the accident of pipeline spills has increased year by year,resulting in the expanding scope of the contaminated environment.Since the first oil spill event occurred in 1969,tens of millions of oil leaks every year,causing serious harm on soil,biological and ecological environment.In this paper,aiming at the diffusion characteristics of the oil spill in the water or soil,the author introduces some concepts such as the cleaning efficiency,leakage volume equivalent on the basis of extensive research at home and abroad,which is combined with Chinas oil pipeline transportation.Then establish an appropriate risk calculation model in order to quickly calculate quantitatively the harmful consequences to the river,soil and ecological environment of the oil pipeline leaks,providing a scientific basis for decider to take a reasonable solution and effective way to bring the harm under control.
