央视网消息：近期，全国多地气温下降，迎峰度冬能源保供工作进入关键期。位于山东济宁的梁山港地处京杭运河和瓦日铁路的交汇点， 是山西、陕西、内蒙古等地区煤炭东运的的重要枢纽。今年，港口采取多项新举措提升冬季能源保供能力。来看记者发回的报道。 济宁市梁山县的梁山港是京杭运河上重要的港口之一，也是铁路、水路和公路联运的一个重要枢纽，入冬以来每天都有六七万吨的煤从山 西、陕西、内蒙古等地区通过瓦日铁路运到这里，再从这里装船通过运河运往长三角地区，有力保障那里的能源供应。 在现场，大家可以看到大型起重机正在往船上装集装箱，这是今年港口新推出的一种"水铁直连"的煤炭运转模式，就是把集装箱的煤通过 铁路运到这里，不再经过卸煤和存储的过程，而是通过精准的需求调度把集装箱直接装船，通过运河发往目的地。这种方式大幅缩短了煤炭运 输的周期，把整个周期从5天缩短到3天，也提升了港口能源保障的效率和能力。 梁山港之所以能够对长三角地区的能源供应发挥着重要保障作用，首先是源于它优越的地理位置。透过示意图可以看到，这条红色的线路 是瓦日铁路，它连接了山西省吕梁市瓦塘镇和山东日照，是山西、陕西等地煤炭东运的铁路大动脉，每年的煤炭运输量近1亿吨 ...
