2015年4月25日14時(shí)11分,尼泊爾首都加德滿都在一陣地動(dòng)山搖之后,隨即被籠罩在了塵埃之中。4年過(guò)去,如今的尼泊爾已經(jīng)從那場(chǎng)8.1級(jí)的地震中恢復(fù)了平靜,只有杜巴廣場(chǎng)上那些還在修復(fù)重建的寺廟、樓宇,提醒著人們,這里曾經(jīng)發(fā)生的災(zāi)難。
人類(lèi)擴(kuò)張活動(dòng)版圖的歷程,也是人類(lèi)與自然相融相爭(zhēng)的一部史詩(shī)。從近兩千年前,被火山付之一炬的龐貝古城;到2004年,印尼北部蘇門(mén)答臘島亞齊省海域發(fā)生里氏8.7級(jí)地震,引發(fā)強(qiáng)烈海嘯;到2008年5月12日,汶川特大地震留下的傷痛;再到2010年1月,巴基斯坦北部罕薩谷Atabad山體滑坡形成堰塞湖,淹沒(méi)數(shù)個(gè)村莊和部分喀喇昆侖公路……而這其中,汶川特大地震影響尤為嚴(yán)重,是中華人民共和國(guó)成立以來(lái)破壞力最大的地震,為此國(guó)務(wù)院特批,自2009年起,每年5月12日為全國(guó)“防災(zāi)減災(zāi)日”。
從地質(zhì)構(gòu)造及板塊活躍度來(lái)看,“一帶一路”沿線國(guó)家與地區(qū)地質(zhì)構(gòu)造復(fù)雜、地震活動(dòng)頻繁,加之受季風(fēng)氣候影響,降水集中且強(qiáng)度高,地震、地質(zhì)、氣象、海洋等自然災(zāi)害極為發(fā)育。據(jù)聯(lián)合國(guó)災(zāi)害數(shù)據(jù)庫(kù)數(shù)據(jù)顯示,“一帶一路”沿線國(guó)家相對(duì)災(zāi)害損失是全球平均值的2倍以上,災(zāi)害死亡率遠(yuǎn)遠(yuǎn)大于全球平均水平,其中南亞和東亞地區(qū)高出全球平均數(shù)的10倍。
“一帶一路”沿線國(guó)家大多是發(fā)展中國(guó)家,這些國(guó)家應(yīng)該如何提高防災(zāi)減災(zāi)能力,滿足當(dāng)?shù)亟?jīng)濟(jì)社會(huì)發(fā)展安全需求?各國(guó)應(yīng)該如何聯(lián)合行動(dòng),開(kāi)展更加有效的防災(zāi)減災(zāi)行動(dòng)?
5月11日-12日,“一帶一路”防災(zāi)減災(zāi)與可持續(xù)發(fā)展國(guó)際學(xué)術(shù)大會(huì)上,來(lái)自全球40余個(gè)國(guó)家和地區(qū)的780余名專(zhuān)家學(xué)者齊聚北京,為科學(xué)應(yīng)對(duì)“一帶一路”沿線國(guó)家共同面對(duì)的減災(zāi)需求,推動(dòng)落實(shí)聯(lián)合國(guó)《2015-2030年仙臺(tái)減少災(zāi)害風(fēng)險(xiǎn)框架》《巴黎氣候變化協(xié)議》和《2030年可持續(xù)發(fā)展議程》,攜手國(guó)際伙伴共建科技協(xié)同減災(zāi)機(jī)制建言獻(xiàn)策。
The history of human’s expansion activities is also a process of integration and struggle between human and nature. About 2,000 years ago, Pompeii was ruined by volcanic eruption; in 2004, a major earthquake of 8.7 magnitude happened in sea area of Aceh, Sumatra in north of Indonesia, triggering strong tsunami; on May 12, 2008, the 2008 Wenchuan earthquake jolted China; in January 2010, a landslide happened in Attabad Lake, Gojal Valley in north of Pakistan, submerging several villages and part of China-Pakistan highway. Among those disasters, 2008 Wenchuan earthquake was the most devastating. In this connection, the State Council approved May 12 as “Disaster Prevention and Mitigation Day” since 2009.
Judging from the geological structure and plate activity, countries and regions along the Belt and Road (the route) have complex geological structure and frequent seismic activity. These, plus impacts of monsoon climate and intensive and strong precipitation, make those countries and regions vulnerable to earthquake and other natural disasters of geology, meteorology, and marine. According to disaster database of the UN, the relative disaster loss of countries and regions along the route is more than two times of global average, and the disaster mortality is far higher than global average. Moreover, those of South Asia and East Asia are 10 times above global average.
Most of these countries are developing ones. So, what should they do to enhance the capacity of disaster prevention and mitigation and meet local demands for security of economic and social development? What measures should they take to act together and launch more effective disaster prevention and mitigation activities?
On May 11-12, at International Conference on Silk Road Disaster Risk Reduction and Sustainable Development, some 780-plus experts and scholars from 40-plus countries and regions gathered in Beijing International Convention Center. They offered suggestions and insights on how to tackle with the common disaster mitigation demands of countries and regions along the route, implement the UN’s Sendai Framework for Disaster Risk Reduction 2015-2030, Paris Agreement, and 2030 Agenda for Sustainable Development, and how to co-build a coordinated technological disaster mitigation mechanism together with global partners.
2018年8月12日凌晨,四川茂縣南新鎮(zhèn)牟托村水磨溝組受短時(shí)降雨影響,突發(fā)泥石流災(zāi)害,因在災(zāi)害發(fā)生前,監(jiān)測(cè)預(yù)警工作及時(shí)到位,為緊急避險(xiǎn)轉(zhuǎn)移贏得了寶貴時(shí)間,共轉(zhuǎn)移240余人,未造成人員傷亡。這次成功的轉(zhuǎn)移是科學(xué)防災(zāi)減災(zāi)的一次有效實(shí)踐。
如何利用科學(xué)手段,在防災(zāi)減災(zāi)上提高效率,成為本次大會(huì)的一個(gè)重要議題。
會(huì)上,專(zhuān)家學(xué)者們圍繞災(zāi)害數(shù)據(jù)調(diào)查與共享、形成機(jī)理與物理過(guò)程、風(fēng)險(xiǎn)分析與管理、監(jiān)測(cè)及早期預(yù)警、防災(zāi)減災(zāi)與應(yīng)急管理、災(zāi)后恢復(fù)重建、跨境災(zāi)害風(fēng)險(xiǎn)防范、可持續(xù)發(fā)展等議題作了探討,提出要在“一帶一路”框架下,聚焦減災(zāi)與可持續(xù)發(fā)展,充分凝聚國(guó)際共識(shí),謀劃減災(zāi)科技合作新路徑,搭建國(guó)際協(xié)同減災(zāi)新平臺(tái),致力于促進(jìn)各國(guó)更加科學(xué)、更加有效地應(yīng)對(duì)重大自然災(zāi)害風(fēng)險(xiǎn),為推動(dòng)沿線國(guó)家可持續(xù)發(fā)展、增進(jìn)各國(guó)民生福祉給出科技方案,為共建“一帶一路”和促進(jìn)各國(guó)共同繁榮提供有力的科技支撐。
在“一帶一路”防災(zāi)減災(zāi)與可持續(xù)發(fā)展國(guó)際學(xué)術(shù)大會(huì)鐵道工程分論壇上,中國(guó)中鐵二院工程集團(tuán)有限責(zé)任公司總經(jīng)理朱穎分享了成蘭鐵路減災(zāi)選線的“中鐵智慧”。
建設(shè)中的成蘭鐵路,位于成都平原向青藏高原邊緣過(guò)渡區(qū)——川西北三角形斷塊區(qū),主要構(gòu)造由龍門(mén)山褶皺斷裂帶、西秦嶺褶皺斷裂帶和次級(jí)岷江斷裂帶組合而成。該區(qū)域位于著名的“南北向地震構(gòu)造帶”的中段,是我國(guó)活動(dòng)斷裂和地震強(qiáng)烈的集中地帶之一。
朱穎介紹說(shuō),“山區(qū)鐵路選線,要以規(guī)避、防范鐵路全壽命周期(建設(shè)及運(yùn)營(yíng)期間)可能發(fā)生的地質(zhì)災(zāi)害為根本出發(fā)點(diǎn),降低、減小鐵路工程建設(shè)及營(yíng)運(yùn)期間的地質(zhì)災(zāi)害風(fēng)險(xiǎn)損失?!?/p>
因此,在成蘭鐵路施工的過(guò)程中,在滿足線路宏觀走向的情況下,為最大限度降低龍門(mén)山斷裂帶(束)對(duì)線路及工程的影響,規(guī)避沿線不良地質(zhì),避免地震引起的山體失穩(wěn)、泥石流、危巖落石等次生災(zāi)害,線路東移,經(jīng)龍門(mén)山前山斷裂破裂的末端、地震次生災(zāi)害相對(duì)明顯較輕的間隔性廊道,采取隧道形式大角度穿越龍門(mén)山活動(dòng)斷裂帶,避開(kāi)岷江河谷下游嚴(yán)重的岸坡穩(wěn)定問(wèn)題。
在經(jīng)濟(jì)全球化趨勢(shì)下,科技創(chuàng)新是應(yīng)對(duì)氣候變化、自然災(zāi)害等全球性問(wèn)題的重要出路。而成果的共享,則是提升風(fēng)險(xiǎn)防控最行之有效的路徑。
當(dāng)中國(guó)科學(xué)院院士崔鵬在談起成果共享的話題時(shí),提起了他曾經(jīng)征戰(zhàn)的喀喇昆侖公路。
喀喇昆侖公路是一條連接中國(guó)西部與巴基斯坦的交通大動(dòng)脈,也是世界上平均海拔最高的跨境國(guó)際公路之一,地質(zhì)情況極為復(fù)雜,區(qū)域內(nèi)雪崩、泥石流、山體滑坡、塌方等地質(zhì)災(zāi)害頻發(fā)。
復(fù)雜的地質(zhì)條件,意味著無(wú)數(shù)的未知風(fēng)險(xiǎn)。在公路修建的10余年里,多名中巴建設(shè)者獻(xiàn)出了寶貴的生命。進(jìn)入新世紀(jì)后,巴基斯坦對(duì)這條公路提出了擴(kuò)建升級(jí)需求,提高道路的防災(zāi)標(biāo)準(zhǔn)和通行能力是當(dāng)務(wù)之急。
2008年,擴(kuò)建升級(jí)項(xiàng)目正式啟動(dòng)。與建設(shè)之初相比,40年后的施工條件發(fā)生了翻天覆地的變化,但巴基斯坦北部的地質(zhì)條件依然給工程帶來(lái)巨大挑戰(zhàn)。2010年,項(xiàng)目中段發(fā)生嚴(yán)重山體滑坡,垮塌的半座山截?cái)嗔松较碌暮恿?,形?0多公里長(zhǎng)的堰塞湖。
面對(duì)這樣一個(gè)堰塞湖,中方團(tuán)隊(duì)專(zhuān)門(mén)請(qǐng)來(lái)了從事泥石流等山地災(zāi)害研究20多年的崔鵬院士,經(jīng)過(guò)綜合考察、科學(xué)評(píng)估,崔鵬團(tuán)隊(duì)提出了堰塞湖改線的應(yīng)對(duì)措施,即通過(guò)新建5條總長(zhǎng)7公里的隧道,同時(shí)架設(shè)4座橋梁并鋪設(shè)14公里路面,來(lái)解決堰塞湖難題。
2013年11月,除改線段外,喀喇昆侖公路改擴(kuò)建工程一期全部完工。2015年9月,堰塞湖改線工程通過(guò)驗(yàn)收。
氣候變化和災(zāi)害影響是當(dāng)前全球共同關(guān)注的問(wèn)題,特別是基礎(chǔ)設(shè)施建設(shè)可能帶來(lái)的災(zāi)害加劇、生態(tài)退化、環(huán)境破壞等影響,除了運(yùn)用科學(xué)技術(shù)積極應(yīng)對(duì)外,也需要國(guó)際社會(huì)通力合作。
為此,在此次學(xué)術(shù)大會(huì)上,由中國(guó)科學(xué)院水利部成都山地災(zāi)害與環(huán)境研究所、四川大學(xué)災(zāi)后重建與管理學(xué)院、中國(guó)科學(xué)院地理科學(xué)與資源研究所共同發(fā)起的國(guó)際減災(zāi)科學(xué)聯(lián)盟正式成立。同時(shí),參會(huì)的中外科學(xué)家還共同發(fā)表了《“一帶一路”防災(zāi)減災(zāi)與可持續(xù)發(fā)展北京宣言》,提出將共同致力于加強(qiáng)科技及政策交流,推進(jìn)構(gòu)建“一帶一路”自然災(zāi)害風(fēng)險(xiǎn)防范協(xié)同機(jī)制。
早在2013年,中國(guó)科學(xué)院成都山地災(zāi)害與環(huán)境研究所就與意大利國(guó)家研究委員會(huì)水文地質(zhì)災(zāi)害防治研究所達(dá)成共識(shí),建立中意山地災(zāi)害聯(lián)合實(shí)驗(yàn)室。實(shí)驗(yàn)室建成后,先后開(kāi)展了“滑坡、泥石流監(jiān)測(cè)與風(fēng)險(xiǎn)管理”等項(xiàng)目研究,為雙邊緊密合作與交流,加強(qiáng)泥石流、滑坡等山地災(zāi)害防治的研究工作打下了堅(jiān)實(shí)基礎(chǔ)。
中科院院士崔鵬在接受記者采訪時(shí)表示:“建立聯(lián)合實(shí)驗(yàn)室對(duì)提升中意兩國(guó)防災(zāi)減災(zāi)的科研水平,促進(jìn)兩國(guó)減災(zāi)事業(yè)的發(fā)展和實(shí)現(xiàn)科技惠民目標(biāo)均具有重要意義,能有效促進(jìn)兩國(guó)互惠共贏!”他認(rèn)為,科學(xué)的防災(zāi)減災(zāi)是沿線國(guó)家共同面臨的重大現(xiàn)實(shí)問(wèn)題,也是各國(guó)間合作的“最大公約數(shù)”。
中國(guó)科學(xué)院院長(zhǎng)、“一帶一路”國(guó)際科學(xué)組織聯(lián)盟主席白春禮:
科技創(chuàng)新與國(guó)際合作對(duì)于“一帶一路”沿線國(guó)家和地區(qū)攜手應(yīng)對(duì)重大自然災(zāi)害風(fēng)險(xiǎn)、保護(hù)生態(tài)環(huán)境安全和實(shí)現(xiàn)國(guó)際社會(huì)經(jīng)濟(jì)繁榮與可持續(xù)發(fā)展具有重要意義。作為中國(guó)的科技國(guó)家隊(duì),中國(guó)科學(xué)院有責(zé)任和義務(wù)為建設(shè)安全、綠色、可持續(xù)發(fā)展的“一帶一路”貢獻(xiàn)科技智慧和力量。
