近日，宁波、洛阳等城市地铁规划被审批部门搁置的消息引起社会关注，这标志着我国城市地铁建设正 在告别规模扩张，步入质量提升的新阶段。 另一方面，也需要清醒认识到，地下空间是城市稀缺生态资源，承载着稳定地质结构、维系地下水循环 的核心功能。据测算，每公里地铁隧道施工需扰动约10万立方米土壤，产生的弃土不仅占用土地，更可 能破坏地下含水层与土壤微生物群落。如个别城市部分区域因地铁施工导致地面沉降，预计修复周期长 达20年；地铁穿越湿地时曾因防护不当造成局部植被枯萎，还需要投入大量资金进行生态修复。这些案 例说明，地质生态系统一旦破坏便难以逆转，生态欠账远非短期经济收益所能弥补的。 地铁建设算好生态低碳账，既是对资源约束的清醒认知，更是新时代城市建设高质量发展的必然要求。 笔者认为，当前亟须强化地铁建设生态环保硬性约束。 一是完善环境影响评价生态指标体系。要将地下空间资源承载力、地质稳定性、地下水保护、生态敏感 区影响等纳入核心指标，细化土壤污染风险、生物栖息地扰动、噪声扬尘控制等量化标准，严格编制生 态修复方案，形成"前期评估—中期监测—后期修复"的全周期闭环管理。如北京地铁新线路规划将生态 评估提前至规划初期，评 ...

近年来，随着国家城市轨道交通审批从严从紧，多地新一轮轨道交通建设规划也因不满足客流强度、财 政收入等因素被搁浅。 近日，宁波市发展改革委在民生e点通问政平台回复网友提问时表示：根据国家最新政策要求，宁波市 申报轨道交通第四期建设规划的条件尚不成熟，待达到条件后再行上报。对于其中的缘由，宁波市发展 改革委在回复网友提问时称，目前宁波市轨道交通客流强度有待提升。 除了宁波，今年3月，洛阳市发展改革委在回复网友"洛阳轨道交通二期工程进度"咨询时就表示：受客 流强度、一般公共预算收入等指标约束，目前我市申报建设地铁二期的条件暂不成熟。下一步将结合国 家政策扎实做好各项工作，在达到各项报批条件后，集中力量推进地铁二期建设。 根据洛阳交通投资有限公司发布的数据，客流强度方面，目前洛阳地铁1号、2号线平均客流强度为每日 每公里0.46万人次，尚未达到每日每公里0.7万人次的标准；一般公共预算收入方面，截至2024年年底， 洛阳市本级和区级一般公共预算收入261亿元，尚未达到300亿元标准。 针对上述情况，一位地方政府人士对《中国经营报》记者表示，从2017年包头地铁项目被中央叫停之 后，地铁审批和建设的风向明显发生变化，近 ...
