城市“进化”,创新蝶变
人民大会堂、国家大剧院、北京大兴国际机场、国家速滑馆……一个个地标建筑,见证了北京在发展中不断优化城市格局,完善城市服务,建设国际一流的和谐宜居之都的轨迹。“新地标——北京城市的‘进化史’”专场上,这些地标的建筑师们介绍了建筑的诞生故事,讲述了他们眼中的城市“进化史”。
不断“进化”着的还有北京的轨道交通。地铁是城市融入现代化交通的显著标志,同时也是城市发展和科技水平的重要体现。
从2008到2022,一座城市、两段奥运缘。14年来,从奥运支线到冬奥支线,从8条线、200公里到27条线、近800公里。飞速发展的北京轨道交通不仅承载着亿万人的“奥运情”“北京梦”,也见证了“双奥之城”的蝶变。在“从北京的地下路过”主题上,北京市轨道交通相关负责人带领观众“复盘”了北京地铁的发展史,也分享了他们在北京的地铁站设计、地铁驾驶等工作中发生的有趣故事。
绿色生态,全民共享
近年来,北京的生态建设取得了显著成果,越来越多的湿地公园、优美河湖出现在市民身边,成为备受市民喜爱的休闲观光区。
2月2日是“世界湿地日”,当天的活动以“乘风破浪的‘治水人’”主题,邀请了延庆区自然保护地管理处副主任刘雪梅,延庆区自然保护地管理处科普宣教科科长李昀倩等嘉宾参与直播,与直播间的市民畅聊他们各自在保护湿地、评选优美河湖和担任“河长”的工作中发生的故事。
北京日报报业集团记者叶晓彦介绍,随着优美河湖评定工作的开展,这一评定正在从专业化向大众化过渡,也正有越来越多的市民群众能够参与河湖治理和保护的工作中来。共治、共管、共享,北京美好的生态环境是大家共同参与维护的结果。
冰雪之上,圣火“飞扬”
在“双奥之城·看典”的直播间里,有冬奥会和冬残奥会的火炬火种灯的设计者,也有服务冬奥保障的工作者,还有努力推动冰雪进校园、推进实现“三亿人上冰雪”目标的民间奥运文化的推动者。他们在“双奥之城·看典”中讲述了自己与冬奥、与冰雪的缘分,与观众分享了奥运精神与冰雪运动赋予自己的激情与快乐。
2月4日是2022北京冬奥会的开幕日,奥运圣火在鸟巢点燃。当天的直播以“圣火飞扬”为主题,邀请了冬奥会和冬残奥会的火炬火种灯的设计者李剑叶,奥运特许商品销售相关负责人饶杰以及奥运藏品收藏者张文全等嘉宾参与活动,分享他们各自与奥运的缘分。
冬奥会火炬“飞扬”的设计者李剑叶讲述了在从设计到成品中自己团队经历的众多幕后故事,象征着生命力的火炬外形、体现传统文化的榫卯结构、凸显绿色理念的环保氢燃料等,回顾先进科技与中华文化在火炬上完美融合的历程。
“最密”站网,精准监测
天气是冬奥会成功举办的重要因素之一。2月9日,以“太阳照常升起”为主题的直播活动,邀请延庆区气象服务组副组长张曼,北京市气象台首席预报员、冬奥开闭幕式预报服务保障团队队长翟亮等嘉宾参与,为观众介绍了2022北京冬奥精准气象服务使用的创新科技,以及冬奥气象保障里有关监测、科研和预报的“奥秘”。
据介绍,北京在“十里不同天”的海陀山建设了17套自动气象站、4套便携自动气象站的地面监测系统,还在赛区建设了S波段天气雷达、激光测风雷达的垂直监测系统,完成了延庆赛区周边38套自动气象站的升级改造工作,组建的“三维、秒级、多要素”的气象综合监测系统,是目前冬奥会历届赛事中最为稠密的监测站网。
截至2月20日,“双奥之城·看典”活动累计直播访问量达8105.7万次,累计网络点击率达突破5000万次,直播点击和阅读量达到1.3亿次。未来,北京将用更具时代气息和人文关怀的美好与繁荣,向世界展示“双奥之城”的独特风采。(完)
中新网评:处理核污水绝不是日本自家私事****** 中新网北京1月19日电(蒋鲤)日本政府近日称,将于2023年春夏期间开始向海洋排放经过处理的福岛第一核电站核污水。日本罔顾国内民众及周边国家的屡屡反对,企图将核污水“一倒了之”,把一件关乎全球海洋生态环境和公众健康的事当成了自家私事。 资料图:日本福岛第一核电站。2011年,福岛核电站事故发生后,大量放射性物质泄漏到大气层和太平洋,对周围环境造成了难以逆转的伤害,数十万人被迫撤离该地区。时至今日,作为日本邻国之一的韩国仍未解除福岛海鲜禁令。 日本以核污水存储能力即将达到上限为由,在2021年4月13日,正式决定将福岛第一核电站核污水排入太平洋。过去一年多,日本政府和东京电力公司一直在持续推进核污水排海计划。 日本政府辩称,这些核污水经多核素处理系统(ALPS)处理后很安全,甚至“可以喝”,这样的表态无疑在愚弄大众。 事实上,经过处理的核污水仍含有多种放射性物质,核污水一旦排放入海就无法回收,长期来看,将会给海洋生态带来难以估量的潜在威胁,最终危害人类健康。 因此,核污水排海计划推出后,遭到日本民众强烈反对。日本《朝日新闻》2022年3月公布的问卷调查显示,福岛县、宫城县和岩手县受访的42个市町村长中,约六成反对东京电力公司福岛第一核电站核污水排放入海。日本全国渔业协会联合会也多次申明立场,反对该计划。 日本政府认为,核污水排海是最便宜、最省事的解决方案,但此举却将周边国家乃至全世界置于核污染风险中。太平洋非日本一家之海,核污水会随着洋流流动,其影响势必会跨越国界,危害周边国家乃至整个国际社会的公共福祉和利益。 《韩国经济新闻》发文称,相关研究认为,福岛核污水如果排放入海,约7个月后将到达济州等韩国海域,该国水产业和旅游业将遭受相当大的损失。 德国南极海洋机构也曾发出警告,若日本将所有核污水排入海中,不到半年,整个太平洋都将面临高度辐射威胁,包括远在大洋另一端的美国。太平洋地区人民更是对日本该计划持反对意见。 日本作为《联合国海洋法公约》缔约国,有义务保护海洋环境。然而,在核污水排海方案的正当性、核污水数据的可靠性、净化装置的有效性、环境影响的不确定性等问题上,日本未能作出科学、可信的说明。 国际原子能机构技术工作组虽已三次赴日实地考察评估,但尚未就日排海方案的安全性给出结论,并且对日本提出诸多澄清要求和整改意见。在此情况下,日本仍执意推进核污水排海工程建设,这是极不负责任的行为。 太平洋不是日本的下水道,日本必须正视各方合理关切,在与周边国家等相关利益方和国际原子能机构充分协商后,制定合理的核污水处理方案。日本也要着眼长远,若只顾眼前,执意将核污水排放入海,不仅其自身,周边国家乃至全世界都将为之买单,其后果必将会危害数代人。 Fukushima water disposal by no means Japan’s own business By John Lee (ECNS) -- Japan has announced it will release treated wastewater from the wrecked Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean this year. Although Fukushima wastewater disposal affects global marine ecological environment protection and public health, Japan has turned a deaf ear to domestic and international opposition to dumping the contaminated water into the sea, treating the "global" matter as its own business. The Fukushima accident in 2011 had sent large quantities of radiation into the atmosphere and the Pacific Ocean, causing irreversible damage to the surrounding environment, and hundreds of thousands of people were forced to evacuate the area. South Korea still maintains its import ban on Japanese seafood from areas affected by the Fukushima nuclear disaster. On April 13, 2021, Japan announced it had decided to discharge contaminated radioactive wastewater in Fukushima Prefecture into the sea due to dwindling storage space, with the Japanese government and plant operator Tokyo Electric Power Company Holdings Inc. promoting the release plan over the past year. The Japanese government argues that the water treated by an advanced liquid processing system, or ALPS, is safe and drinkable, which is undoubtedly fooling the public. In fact, the treated wastewater still includes a variety of radioactive substances and can’t be recycled once discharged into the sea, which will pose a great threat to marine ecology and ultimately endanger human health in the long run. Therefore, the discharge plan has been strongly opposed in Japan. According to a questionnaire conducted by The Asahi Shimbun, nearly 60 percent of mayors of 42 municipalities in Iwate, Miyagi and Fukushima prefectures oppose the discharge plan. The National Fisheries Cooperative Federation of Japan has also repeatedly stated its opposition in public. The Japanese government believes that dumping Fukushima wastewater into the sea is the cheapest and most convenient solution, but neighboring countries and even the whole world will be at risk of nuclear pollution. The Pacific Ocean doesn’t belong to Japan and the wastewater flow along oceanic currents will surely break boundaries and endanger public welfare and the interests of neighboring countries and even the international community. The Korea Economic Daily reported that related research concluded that if contaminated water from Fukushima is released into the ocean, it would only take seven months for the contaminated water to reach the shores of Jeju Island, with the country's aquaculture and tourism suffering considerable losses. According to the calculation of a German marine scientific research institute, radioactive materials will spread to most of the Pacific Ocean within half a year from the date of discharge, and the U.S. and Canada will be affected by nuclear pollution. People in the Pacific region also oppose the discharge plan. As a participant of the United Nations Convention on the Law of the Sea, Japan has the obligation of protecting the marine environment. However, it hasn’t offered a full and convincing explanation on issues like the legitimacy of the discharge plan, the reliability of data on the nuclear-contaminated water, the efficacy of the treatment system or the uncertainty of environmental impact. Though the IAEA has yet to complete a comprehensive review after three investigations in Japan, the Japanese side has been pushing through the approval process for its discharge plan and even started building facilities for the discharge. It is rather irresponsible for Japan to act against public opinion at home and concerns abroad. The Pacific Ocean is not a private Japanese sewer. The country must seriously heed the voices of the international community and make a reasonable plan for the Fukushima wastewater disposal after full consultation with stakeholders and international agencies. If it only seeks instant interest and insists on discharging the contaminated water into the sea, not only itself, but also its neighboring countries and the entire world will pay for the decision and several generations will be forced to bear the consequence.
