中国天然气供应安全战略研究　 （摘编）　 摘〓要：我国天然气资源的勘探 和开发都有较大的潜力，应当立足于本国天然气资源开发，积极、适当地引进一部分国外天 然气资源作为补充，这不仅有利于我国能源消费结构、供需状况和城市大气环境的改善，而 且能促进我国西北、东北地区天然气资源的开发利用。　 关键词：供应安全；天然气；煤层气；液化天然气　　 Chinese natural gas supply security strategic research (Excerpts) Abstract: The exploration and development of Chinas natural gas resource have greater potential; it should be based on domestic natural gas resource development. Meanwhile, we should introduce part of foreign natural gas resources positively and appropriately as a supplement; this will not only benefit the improvement of Chinas energy consumption structure, the supply and demand situation and the citys atmospheric environment, but also can promote the development and utilization of natural gas resources in Chinas northwest and northeast area.
