【摘要】 苏里格南区块气田位于鄂尔多斯高原东南部的毛乌素沙地腹地,自然生态环境十分脆弱,具有极其重要的生态保护价值。通过工程分析,天然气开发必然会对区内生态环境造成巨大的影响,主要体现在对自然植被的破坏和对野生动物的干扰两个方面。为科学预测其生态影响,先后对项目区进行了自然植被和鸟类实地专项调查,查明了自然植被的种类、类型和分布,并首次在项目区发现了国家Ⅱ级重点保护鸟类蓑羽鹤(Anthropoides virgo)的繁殖种群及其主要分布区域,结合工程资料,预测了生态影响,并提出了具体的减缓影响的生态保护措施和建议。更多还原

【Abstract】 Because of locating in the middle of Maowusu sandlot of southeast Ordos plateau,the southern Sulige area of the Inner Mongolia Autonomous Region has vital protected values for its fragile environment. The engineering analysis showed that tremendous impacts to the environment will be taken place during the gas field exploitation by destroying natural vegetation and disturbing wild animals. In order to forecast the ecological impacts accurately,vegetation and birds field survey in this area has been performed successively,species,type and distribution of natural vegetation was found out,and the reproducting population of Anthropoides virgo and its habitats in this area were also found for the first time. Based on the analysis of engineering data,material ecological impacts were forecasted,and some safeguards and suggestions were put forward.更多还原
