Study of Ecological Environment on Assessment Model of Ecosystem Damage Caused by Oil Spill in Ocean

Abstract:

An ecosystem damage assessment model is built in the paper based on the features of marine ecosystem service damages caused by oil spill and traits of ecosystem service after restoration. The ecosystem damages caused by oil spill are mainly reflected in the following six services, namely, the fishery resource supply, gas regulation, waste disposal, disaster defense, entertainment and biodiversity conservation as well as the restoration expense of respective damage. The damage degree of oil spill to each service of marine ecosystem differs, and the recovery time and speed of respective service also vary. According to the change of service value after being damaged, the damage amount of each service is expressed as an integral function of original value, damage degree and recovery speed. Based on the natures and features of each assessment indicators, the method of environmental economics which can judge its original value is selected, and the ecological scale which can measure the damage degree and recovery speed is determined. Expense statistics method is adopted to monetize ecological restoration indicators.
