Abstract


Risk assessment originated from several developed countries in the 1970s, which is a new gradually developing research field and get a rapidly development accompanied by environment management objectives and changing of environmental attitude. The ecological risk assessment is mainly concerned the possibility that ecological system components in different level exposed to single or multiple intimidating factor.We analysis the response characteristics of different functional groups to oil pollutant,and get the instructional species of petroleum contaminated environmental changes, extract the key species which have sensitive reflect to the pollution things.According to oil characteristics and the process of ecological risk assessment receptor options-expose effect-assessment, we establish ecological risk evaluation model frame referencing the relationship between ecological receptor exposure ways and ecological effect. Comprehensive evaluation about the advantages and disadvantages of current ecological risk assessment methods is made in this paper, we select joint probability curve evaluation to establish oilfield ecological risk assessment model and assess oilfield risk,and we select simple GM(1,1) gray model to warn current and future ecological risk. We collect and research the expressing characteristics of structure and function of the land surface ecological system, and analysis the main function and ecological system food web about the land plants and water plants, get the potential risk from the PAHS and COD in Shengli oilfield using the assessment and warn system, so can we provide more reasonable and accurate basis for land oil management.
