“十一五”期间,在国家宏观政策引导和扶持下,全国城市轨道交通投入运营里程达到1000公里左右。目前,国家制定规划的36个城市中已有29个城市的轨道交通规划获得国务院的审批,包括洛阳、包头等一部分极具发展潜力的城市也在积极筹建规划地铁中。未来,我国大约有229个城市具备发展城市轨道交通的潜力,预计到2050年规划线路将增加到289条,总里程数达到11700公里。 During the “Eleventh Five-Year Plan” period, under the guidance and support of the state macroeconomic policy, the operational mileage of urban rail transit in the country reached about 1,000 km. At present, the rail transit planning of 29 cities in 36 cities under state planning has been approved by the State Council. Some cities with great potential for development, including Luoyang and Baotou, are also actively planning the construction of the subway. In the future, about 229 cities in our country have the potential to develop urban rail transit. It is estimated that by 2050, the number of planned routes will increase to 289 with a total mileage of 11 700 km.
