| 摘 要： | 页岩气开发和生产过程影响水资源与水质、土地利用与植被覆盖、土壤侵蚀与土壤质量。综述了页岩气开发和生产过程可能存在的生态环境影响,并重点评价了国际上不同区域页岩气开发和生产对土地利用和植被覆被变化、景观破碎化的影响,以及对土壤侵蚀和土壤质量的影响。研究发现页岩气开发平台、运输道路和管线占用农田、牧场、森林,造成不同程度的景观破碎化,在坡地开发页岩气会导致土壤侵蚀与沉积风险增大。截止2015年末,在我国重庆涪陵焦石坝页岩气产建区55.8%的面积(146.56 km~2)存在土壤侵蚀和石漠化生态风险。我国页岩气开发区水基钻屑固化填埋未对周边土壤造成污染。建议页岩气开发设计应考虑占地、景观破碎化的影响,并及时开展页岩气开发暂时占地的复垦工作。

| Abstract: | Shale gas development and production has potential ecological effects on water resources and quality, land use, vegetation cover, soil erosion, and soil quality. However, the ecological effects of shale gas development and production on vegetation cover and soil erosion have not been reviewed globally. In this paper, the ecological effects during shale gas development and production, including changes of land use and vegetation cover, landscape fragmentation, soil erosion, and soil quality were assessed. Crop, pasture, and forest lands were occupied by well pads, transportation roads, and pipelines and resulted in landscape fragmentation, whereas shale gas development has increased the risks of soil erosion and deposition in slope land. Until the end of 2015, about 55.8% (146.56 km2) of the region was classified as sensitive to soil erosion and Karst rocky desertification in the Fuling Jiaoshiba region, Chongqing, China. In the Chinese shale gas development area, the solidification treatment technology of water-based drilling cuttings in shale gas wells did not pollute nearby soils. We suggested that plans for shale gas development should consider land occupation and landscape fragmentation. Furthermore, temporary occupied land by shale gas development should be reclaimed promptly. |
