Integral Assessment of Environmental Risks of Oil Accidental Spillage

Abstract

There was conducted analysis of main factors of environmental risk of impact  relative to oil pipeline on environment in the area of oil producing regions of West Siberia. There was offered procedure for assessment of environmental risks of oil accidental spillage, which is grounded on the use data of remote sensing of the Earth and application of GIS measures. There were detected oil-contaminated plots on the base of remote sensing data that were presented by satellite images Landsat. There were considered procedural issues of mapping for zones, which vulnerable to anthropogenic impacts. With the aid of satellite images Landsat for two fields regions of West Siberia were computed values of normalized difference vegetation index. There was made assessment of the state and variation in time of  oil-contaminated vegetation cover in “vulnerable” zones on the base of normalized difference vegetation index. Presented approach allows detect and made quantitative assessment of environmental risk as impact factor for oil spillage on environment.
