大庆宋芳屯油田开发对周围草原羊草群落的影响

油田开发过程中 ,由于污染物的排放 ,对油田周围的生态系统将产生一定的影响。以大庆宋芳屯油田开发活动为例 ,通过实地调研和实验 ,分析了油田开发建设对草原羊草群落的影响和羊原群落的恢复规律。结果表明 :油田采油、贮存、运输及其他生产过程中产生大量的环境污染物 ,对油井周围环境中的植物生长发育及作物品质有一定的影响 ;黑钙土和风沙土上的钻井场可在 4～ 5a内恢复为羊草为优势种的群落

Impact of the Development of Songfangtun Oil Field on Aneurolepidium Chinensis of Surrounding Pastures

Development of an oil field often causes pollution to its surrounding areas, negatively affecting the ecological environment therein. The development of Songfangtun Oil Field is cited as an example for the study to illustrate its impact on the surrounding pastures and the regularity of pasture restoration. Results show that during the processes of drilling, oil extraction, storage, conveyance and various other operations, large quantities of pollutants were generated, seriously polluting the pasture and affecting the growth of forage grasses. It takes 4-5 years for the pasture to restore the dominance of Aneurolopidium chinensis in drilling sites of chernozem and aeolian sand soils.
