建設(shè)固若金湯的大都市

建設(shè)固若金湯的大都市

Clay Dillow 2013-06-27
桑迪颶風(fēng)造成洪水圍城之后,紐約市計(jì)劃通過一系列規(guī)模龐大的的工程來(lái)加強(qiáng)它的基礎(chǔ)設(shè)施建設(shè),以此應(yīng)對(duì)氣候變化,而這只是世界各地城市加固運(yùn)動(dòng)的開始。同時(shí),一系列預(yù)測(cè)表明,到這個(gè)十年結(jié)束的時(shí)候,全球的城市恢復(fù)力建設(shè)很可能會(huì)形成一個(gè)價(jià)值數(shù)千億美元的產(chǎn)業(yè)。

????世界其他地方也是如此,而政府需要更多地參與緩解與氣候變化相關(guān)的各種威脅,這一點(diǎn)已經(jīng)越來(lái)越成為全球共識(shí)。這種全球共識(shí)在很大程度上是由過去十年以來(lái)一連串嚴(yán)重自然災(zāi)害所引起的,而且正在催生出一種新的極端型土木工程及建筑項(xiàng)目。而隨著各個(gè)國(guó)家及城市試圖在面對(duì)海平面持續(xù)上升以及惡劣天氣活動(dòng)增加的情況下增強(qiáng)自身的恢復(fù)力,這些項(xiàng)目為全球繁榮做好了充分的準(zhǔn)備。一系列預(yù)測(cè)表明,到這個(gè)十年的末期,恢復(fù)力建設(shè)很可能形成一個(gè)價(jià)值數(shù)千億美元的產(chǎn)業(yè)。

????仿佛是為了印證這種預(yù)測(cè),過去幾個(gè)月以來(lái)突然出現(xiàn)了一系列的設(shè)計(jì)比賽,它們都要求參賽者提交可以成為在災(zāi)害易發(fā)地區(qū)建設(shè)社區(qū)之新標(biāo)準(zhǔn)的“極端天氣型建筑”解決方案。美國(guó)住房和城市發(fā)展部(the U.S. Department of Housing and Urban Development)6月20日推出了一項(xiàng)名為“通過設(shè)計(jì)重建都市”(Rebuild by Design)的廣泛計(jì)劃,旨在專門針對(duì)受桑迪災(zāi)害影響最嚴(yán)重的地區(qū),征詢快速恢復(fù)型建筑設(shè)計(jì)和基礎(chǔ)設(shè)施的新穎設(shè)想。由美國(guó)建筑師協(xié)會(huì)(American Institute of Architects)發(fā)起的“設(shè)計(jì)恢復(fù)力”(Designing Recovery)活動(dòng)要求工程師為三個(gè)具體地區(qū)提出更具恢復(fù)力的住宅解決方案的構(gòu)想,這三個(gè)具體地區(qū)是:密蘇里州喬普林、路易斯安那州新奧爾良以及和紐約市皇后區(qū)。而3C綜合沿海社區(qū)比賽(Comprehensive Coastal Communities)提出了一個(gè)簡(jiǎn)單但棘手的設(shè)計(jì)問題:如何在重建某地區(qū)時(shí)讓其地平面相比以前抬高幾英尺,但又不能使它變得難看?

????如何將這些類型的新解決方案與已經(jīng)通過測(cè)試的土木工程防洪減災(zāi)實(shí)踐結(jié)合起來(lái)?這個(gè)問題將成為紐約市面臨的挑戰(zhàn),因?yàn)榧~約市力圖證明,借助足夠的投資資金以及深思熟慮的規(guī)劃,城市實(shí)際上可以通過加強(qiáng)工程建設(shè)來(lái)繞開海平面上升及其他與氣候變化相關(guān)的威脅。而且,這是全球以第一個(gè)為了增強(qiáng)主要城市地區(qū)應(yīng)對(duì)氣候變化的恢復(fù)力而發(fā)起的這種規(guī)模的重大民用基礎(chǔ)設(shè)施徹底翻修計(jì)劃,世界各地的其他城市都會(huì)拭目以待,看看紐約市打算如何處理這么龐大而復(fù)雜的新體系所需要經(jīng)歷的政治磋商及實(shí)施進(jìn)程,同時(shí)還要看看這項(xiàng)投資是否能夠帶來(lái)回報(bào)。

????卡瓦拉羅說(shuō):“未來(lái)需要作出一些艱難的選擇。某些時(shí)候要保護(hù)某些地區(qū),而這可能會(huì)讓其他地區(qū)懊惱失望,但我們終于要在遭受損失之前先投入一些資金,借以加強(qiáng)防災(zāi)能力。我相信,事先投入一些資金,會(huì)在暴風(fēng)雨來(lái)襲時(shí)省下許多錢。”(財(cái)富中文網(wǎng))

????The same is true elsewhere in the world, and the growing consensus -- largely spawned by a spate of intense natural disasters over the past decade -- that governments need to get more involved in mitigating threats related to climate change is giving rise to a new kind of extreme civil engineering and architecture that is well-positioned for a global boom as cities and states attempt to bolster their own resiliency in the face of rising sea levels and increased severe weather activity. Projections indicate that resiliency construction could very well be its own industry worth hundreds of billions of dollars by the end of the decade.

????As if on cue, a number of design competitions have sprung up in the past few months asking for "extreme weather architecture" solutions that could become the new standard for communities building in disaster-prone regions. The U.S. Department of Housing and Urban Development launched a broad initiative on June 20 titled Rebuild by Design seeking novel ideas for resilient building designs and infrastructure specifically tailored for the areas most devastated by Sandy. Designing Recovery, launched by the American Institute of Architects, asks engineers to concept more resilient residential solutions for three specific areas: Joplin, Mo., New Orleans, La., and Queens, N.Y. And 3C for (Comprehensive Coastal Communities) asks a simple yet tricky design question: How do you rebuild a neighborhood several feet higher than it was before without making it ugly?

????Integrating these kinds of new solutions with tested civil engineering flood mitigation practices will be New York City's challenge as it strives to prove that with enough investment and thoughtful planning, cities really can engineer their way around rising sea levels and other climate change-related threats. And, being the first major civic infrastructure overhaul of this magnitude aimed specifically at enhancing the resiliency of a major urban area with respect to climate change, other cities around the globe will be watching to see how New York manages the politics and implementation of such a vast and complex new system -- and whether the investment pays off.

????"There's going to be some tough choices to make," Cavallaro says. "At some point you're going to protect certain areas probably to the chagrin of other areas. But we're finally going to put some money ahead of the damage. I believe that a little bit of money up front will save a lot money when storms hit."
