Abstract: Bohai rim is the main distribution area of Chinese coastal oilfields, and a typical ecofragile region. Longterm intensive crude oil exploitation seriously destroys the local environment. Although the local oilfield enterprises adopt many measures to curb environmental pollutions, the quality of local ecoenvironment has not been improved. We review the characteristics of ecoenvironment at Chinese Bohai rim, oilfield exploitation history, and the impact of oilfield exploitation on local ecoenvironment. We also present control measures for current oilfield pollutants and the comprehensive governance strategies for the environment of coastal oilfields. This will be a reference for further oilfield exploitation and management.

Key words: environmental protection, oil field, crude oil contamination, ecological impact, Bohai rim
