摘 要：Oil production related activities have led to many environmental *** 80%of the total output of crude oil is generated from terrestrial oilfields in the ***,the impact of oil exploitation procedures on soil animal communities has not been fully *** study investigated the responses of soil nematode communities to the oil exploitation activities in the Yellow River Delta of *** setting 10 oilfield sites and 5 relatively uncontaminated sites(controls),we found that the content of soil total petroleum hydrocarbons(TPH)was significantly higher at oilfield sites than at *** a longer oil exploitation history,the content of soil TPH *** nematode community structure at oilfield sites was largely different from that at *** nematodes were significantly less abundant but more diverse at oilfield sites than at *** proportions of fungal feeders were significantly lower at oilfield sites than at controls,attaining only half of those at *** nematode trophic diversity and genus number negatively correlated with the duration of petroleum exploitation *** study elucidated the difference in soil nematode communities caused by oilfield exploitation and indicated that the nematode diversity was most obviously influenced by the soil TPH content and the oil exploitation history.
