摘要
知識工作者推動了當(dāng)代城市的社會和經(jīng)濟發(fā)展,但他們往往由于久坐的工作狀態(tài)、長期的高強度腦力勞動,以及高度職業(yè)競爭,而心理及生理健康狀況堪憂。因此,為知識工作者提供高質(zhì)量恢復(fù)性鄰近綠地以促進(jìn)他們的健康和福祉已成為一項緊迫的重要需求。盡管許多研究已經(jīng)證明鄰近綠地具有多重健康效益,但這些學(xué)術(shù)理論和研究證據(jù)并不足以有效地為相關(guān)規(guī)劃和設(shè)計實踐提供指導(dǎo)。本研究通過綜合性文獻(xiàn)研究,歸納總結(jié)出能體現(xiàn)工作場所鄰近綠地所帶來健康效益的四個理論機制:1)減輕壓力;2)恢復(fù)注意力和提升景觀偏好;3)促進(jìn)體力活動;4)豐富感官體驗。而后,本文確定了可以提高知識工作者健康和福祉的綠地關(guān)鍵環(huán)境特征。最后,研發(fā)了一套現(xiàn)狀場地恢復(fù)性能力的評價標(biāo)準(zhǔn)及一系列恢復(fù)性鄰近綠地設(shè)計導(dǎo)則,并為聯(lián)系跨學(xué)科研究與實踐提出了一種簡明范式。

Abstract
Knowledge workers drive social and economic development in contemporary cities but often exhibit poor psychological and physical health because of sedentary work, long-term and intense mental labor, and high-level occupational competition. Thus, providing high-quality restorative green spaces in knowledge workers’ proximity to promote their health and well-being has become an important and pressing need. Although the multiple health benefits of proximity to green spaces have been highlighted, the existing planning and design practices are not well supported by scientific theories and evidence. This study interprets the health benefits of proximity to green spaces in work environments considering four theoretical mechanisms: stress reduction, attention restoration and landscape preference, physical activity promotion, and sensory enrichment through an integrative literature review. Next, the paper identifies the key environmental characteristics of green spaces that can enhance the health and wellbeing of knowledge workers. In addition, it develops a set of criteria for evaluating the restorative capacity of existing sites and a set of guidelines to design restorative nearby green spaces, and proposes a simple paradigm to connect interdisciplinary research and practice.

摘要
綠視率是衡量城市品質(zhì)的重要參考指標(biāo)。如何通過適宜的綠視率營造良好人居環(huán)境,提高人體愉悅度是風(fēng)景園林學(xué)的重要研究內(nèi)容。當(dāng)前綠視率對人體愉悅度的影響仍缺少定量研究?;谌皥D測量的全景綠視率可涵蓋超出普通二維圖像的環(huán)境要素,因此本文通過調(diào)查問卷和腦電信號(EEG)數(shù)據(jù),探究不同全景綠視率環(huán)境下個體愉悅度變化規(guī)律。實驗通過依次添加灌木、喬木等植被,精準(zhǔn)控制預(yù)景中的全景綠視率,使其按照0、30%、60%、90%、0的順序變化。研究結(jié)果表明:1)個體愉悅度在初次觀看全景綠視率為0的環(huán)境時最低,并隨全景綠視率增加而提升,全景綠視率為60%時被試愉悅度最高;2)全景綠視率為90%時,被試愉悅度顯著下降,部分被試出現(xiàn)恐懼、壓抑的情緒特征;3)全景綠視率由90%重新回到0時,被試愉悅度明顯提高,主觀體感從枯燥、無聊轉(zhuǎn)為開敞、明亮。上述結(jié)果表明,當(dāng)全景綠視率為60%,人體愉悅度可能最佳;過高的全景綠視率可能給人帶來壓力,并顯著降低愉悅度;交替變化的綠視環(huán)境可能比單一的環(huán)境更能提高游憩愉悅度;綠視率與個體愉悅度之間的復(fù)雜性有待深入研究。本研究成果可為戶外綠化環(huán)境的設(shè)計、優(yōu)化及評估提供科學(xué)依據(jù)。

Abstract
Green View Index (GVI) is a core indicator to measure urban quality. Identifying proper ranges of GVI has become a significant proposition in Landscape Architecture to design environments that can increase individuals’ pleasure level. However, quantitative research on the pleasure level impacted by varied GVIs is still inadequate. This research explores the changes of pleasure level through EEG data collection and questionnaire survey under panoramic scenarios with different panoramic GVIs, which can represent more environmental elements than two-dimensional images. By adding shrubs and trees gradually, this experiment precisely set five scenarios with the GVI changing from 0 to 30%, 60%, 90%, and 0. Research results show that 1) individuals’ pleasure level dropped to the lowest when they first enter the scenario with a panoramic GVI of 0, but when panoramic GVI increased from 0 to 30% and to 60%, the pleasure level increased and finally researched the highest; 2) in an environment with a panoramic GVI of 90%, individuals’ pleasure level significantly reduced, while some participants self-reported the sense of fear and oppression; and 3) when shifting panoramic GVI from 90% to 0, the bright and open space increased participants’ pleasure level. All these findings reveal that individuals’ pleasure level reached the highest under the scenario with 60% panoramic GVI; extremely high panoramic GVI may lead to negative emotions; and landscape with carefully designed panoramic GVIs can improve one’s pleasure level. Future research may probe into the relationship between GVI and individuals’ pleasure level from more perspectives to provide reference for the design, optimization, and evaluation of outdoor urban greening.

摘要
為了解人們在商業(yè)步行街上的注意力分布情況,理解街道體驗相關(guān)的視覺認(rèn)知過程,本研究選擇上海市南京路步行街作為實驗場地,采用頭戴式眼動儀探究參與者自然狀態(tài)下行走時的注意力關(guān)注點,同時結(jié)合目的地選擇、興趣點拍照、深度訪談多種實驗任務(wù),以激發(fā)參與者真實的行為決策。研究采用自動語義分割與人工識別結(jié)合的方法,分析并統(tǒng)計各環(huán)境要素的眼動興趣區(qū)注視情況,并引入“信息密度”這一眼動新指標(biāo)(即主觀注視比例與客觀畫面面積占比的比值),以反映環(huán)境要素或區(qū)域?qū)ψ⒁饬Φ奈潭?。研究結(jié)果顯示,環(huán)境要素的信息密度具有差異:外掛店招、建筑入口空間、品牌標(biāo)識和電子屏幕的信息密度最高,其次是綠化和人群,建筑立面、天空和地面最低。通過對以外掛店招為代表的高信息密度環(huán)境要素進(jìn)行系統(tǒng)性設(shè)計,有助于塑造特色鮮明的街道景觀體驗。此外,研究結(jié)果顯示,當(dāng)環(huán)境體驗與個人經(jīng)歷相關(guān)并被賦予情感價值時,容易導(dǎo)致正向的認(rèn)知判斷結(jié)果,促進(jìn)環(huán)境吸引力的形成。

Abstract
To understand the attention distribution and visual cognition in streets, this study conducted an experiment on Nanjing Road Pedestrian Mall (Street) using Head-mounted eye-trackers. Participants’ attention distribution were analyzed via Area Of Interest (AOI) during real-life walking scenarios, combining with several experiment tasks (i.e., destination selection, point-of-interest photography, and in-depth interviews), to capture participants’ naturalistic decision-making. The study combined automatic semantic segmentation with manual audit to code participants’ attention fixation duration and proportion by AOIs. A new indicator “information density,” which is the ratio of the attention percentage to the exposure percentage of a given environmental element, was introduced to describe the efficiency of environmental elements on attracting attentions. Findings revealed information density varies across environmental elements: higher information density was found in sign, building entrance, brand name, and poster; the lower was found in building, sky, and ground; while tree and person fell in between. Findings hence suggest environmental elements of higher information density (such as business signs) should be systematically designed to enhance desired experiences. Findings also indicated that personalized experiences are more likely to induce positive associations about environment which eventually lead to place attachment.

摘要
我們可以將氣候危機看作一種威脅,也可以將之視為一種機遇,因為它促使不同文化、學(xué)科和行業(yè)前所未有地團結(jié)一致,這種團結(jié)有望徹底改變最初導(dǎo)致氣候危機的根深蒂固的惡性循環(huán)。
本文評述了景觀設(shè)計師在多學(xué)科綜合性氣候適應(yīng)語境中的專業(yè)性,即“景觀專長”(landscape expertise)。當(dāng)代景觀設(shè)計學(xué)科中以“系統(tǒng)”和“過程”為主導(dǎo)的思維模式,能成為跨學(xué)科氣候行動、團結(jié)協(xié)作的強有力工具。然而,在現(xiàn)實中,氣候相關(guān)的討論通常由決策者、科學(xué)家和工程師主導(dǎo),景觀專長仍然被忽視甚或邊緣化;如今的景觀設(shè)計師仍然面臨著其他學(xué)科專家的誤解——在本文作者過去的多學(xué)科合作經(jīng)歷中,許多其他領(lǐng)域的專家僅簡單地將景觀設(shè)計等同于美學(xué)和生態(tài)層面的設(shè)計,而忽視了景觀設(shè)計師在解決復(fù)雜、多元問題時重視“系統(tǒng)”和“過程”的思維方法,而本文恰旨在回應(yīng)這一對景觀專長理解上的欠缺。
文章首先通過剖析美國弗吉尼亞州的一項由政府領(lǐng)導(dǎo)的大規(guī)模海岸適應(yīng)總體規(guī)劃實踐,梳理出當(dāng)前世界氣候適應(yīng)實踐工作所涉及的專業(yè)領(lǐng)域。文章繼而對過去二十年間一系列景觀設(shè)計項目進(jìn)行了理論分析,并提出了三個術(shù)語——“空間化”(spatialize)、“融合”(synthesize)和“推想”(speculate)——以闡釋多學(xué)科綜合性氣候適應(yīng)項目中景觀專長的內(nèi)涵?!翱臻g化”是指景觀設(shè)計師通過戰(zhàn)略性地展示“數(shù)據(jù)”,批判性地審讀地圖和構(gòu)建知識的能力。“融合”是指景觀設(shè)計師通過物理空間實踐,統(tǒng)籌考量文化、生態(tài)、歷史、生物和政治等視角,來構(gòu)想“多物種共生”的愿景?!巴葡搿敝荚趯⒕坝^設(shè)計視為一種必須頻繁運營的長期實踐,從而將景觀設(shè)計視為“基于實踐產(chǎn)生知識”的探索性框架,而非由理論知識主導(dǎo)實踐的過程。

Abstract
This article maps out landscape architects’ expertise in multidisciplinary, comprehensive climate adaptation discourse. Systemic frameworks and process-driven approaches in contemporary Landscape Architecture discipline can become a powerful tool for harnessing unprecedented solidarity for climate actions across fields. However, landscape expertise is still largely ignored or marginalized in real-life climate discourse dominated by policymakers, scientists, and engineers. This study addresses this gap in understanding landscape expertise through design research projects over the past two decades. The article theorizes a body of landscape architecture projects in the past two decades, and proposes three terms—spatialize, synthesize, and speculate—for describing the landscape expertise in multidisciplinary, comprehensive climate adaptation projects. “Spatialize” refers to landscape architects’ capacity to construct knowledge through strategically displaying “data” through critical cartography. “Synthesize” is the ability to envision multispecies entanglement by combining cultural, ecological, historical, biological, and political lenses through material practices. “Speculate” means to understand landscape design as a long-term practice with repeated operations, and, thus, to design is to deploy a speculative framework that generates knowledge through practice.

摘要
氣候變化對瑞士的高山生態(tài)造成的影響是極為特殊的。由于年平均氣溫不斷上升,當(dāng)?shù)卦S多植物物種的棲息地遭到破壞,它們被迫逐漸向海拔更高的區(qū)域遷移。在旅游經(jīng)濟開發(fā)和先鋒植物物種不斷入侵的雙重影響下,敏感而稀有的植物群落將無力適應(yīng)新的環(huán)境,以致當(dāng)?shù)鼐哂兄匾獌r值的高山草甸日漸衰敗。生物多樣性喪失正迅速成為瑞士舉國關(guān)注的重要生態(tài)問題。
安德馬特鎮(zhèn)位于瑞士中部烏塞倫河谷的東端,地處歐伯拉普、圣哥達(dá)山和富爾卡三個隘口的交匯處,擁有豐富的植物物種。周邊的山脈上坐落著若干“國家堡壘防御計劃”時期遺留下來的軍事掩體和堡壘,其中包括建于1893年的斯托克利堡壘和建于1944年的古奇炮工廠。20世紀(jì)90年代,隨著冷戰(zhàn)的結(jié)束,逾8 000座防御工事逐漸喪失功能,其中一部分與當(dāng)?shù)鼐坝^融為一體。與此同時,精品酒店的大量開發(fā)、為建設(shè)高山滑雪公園而進(jìn)行的斜坡改造等對當(dāng)?shù)氐母呱讲莸樵斐闪藝?yán)重威脅。如不加以干預(yù),該地區(qū)特色植物的生存空間將持續(xù)萎縮,加劇生物多樣性缺失與土壤質(zhì)量下降。
本文所述項目探究了如何將特定軍事基礎(chǔ)設(shè)施融入景觀中,進(jìn)而推動高山植物群落的研究、保護(hù)與復(fù)育。具體策略包括:1)重新引入傳統(tǒng)的放牧管理方式,控制榿木的入侵;2)以斯托克利堡壘和古奇炮工廠為基地,建立高海拔種子庫;3)將古奇炮工廠上方崎嶇不平的景觀改造為一處生態(tài)庭院,促進(jìn)植物的主動與被動繁殖??紤]到部分高山植物生長于海拔較低的區(qū)域,本項目設(shè)計了一套新的種子主動傳播機制,該機制與種子的天然傳播途徑相結(jié)合,充分利用焚風(fēng),可大大增加種子的傳播距離,適應(yīng)不斷變化的氣候條件。廢棄的防御工事由此重獲新生,成為了集生產(chǎn)、研究與教育功能為一體的重要場所。

Abstract
Switzerland’s alpine ecologies are uniquely affected by climate change. Many of the country’s plant species are migrating higher in altitude due to rising annual mean temperature with extensive habitat loss expected in as early as 2050. Given the compounded effects of the growing tourism economy and the expanding presence of aggressive pioneer plant species, regionally significant alpine meadows have been displaced before their sensitive and rare plant communities can adapt. This impending loss of biodiversity is quickly becoming a national ecological redoubt.
Situated at the crossroads of the Oberalp, the St. Gotthard, and the Furka passes, the town of Andermatt lies at the eastern end of the Urseren Valley, a floristically diverse region of Central Switzerland. Abandoned military bunkers and fortresses (Fort St?ckli and Artillery Works Gütsch) overlook Andermatt as relics of the Swiss National Redoubt defence plan.
This project investigates how specific military infrastructure integrated into the landscape can be repurposed into living archives for research, preservation, and propagation of alpine plant communities. Can this design strategy combining active and passive interventions mitigate anthropocentric pressures on these alpine ecologies while providing a new purpose to outmoded military infrastructure? Will a strategically managed ecological retreat preserve Swiss identity beyond the non-human?

摘要
近兩年來,老撾的宏觀經(jīng)濟深受新冠肺炎(COVID-19)疫情影響,北部瑯南塔省的旅游業(yè)也遭受重創(chuàng),迫切需要制定產(chǎn)業(yè)復(fù)蘇計劃以促進(jìn)長遠(yuǎn)發(fā)展。當(dāng)?shù)鼐用駥ν恋貎r值的認(rèn)知與近年來老撾正在施行的“以生產(chǎn)力克服貧困”的改革政策一致:相較于將土地應(yīng)用于復(fù)興生態(tài)旅游業(yè)并提升生態(tài)系統(tǒng)服務(wù)價值,他們更傾向于將土地應(yīng)用于其他產(chǎn)業(yè),如經(jīng)營橡膠種植園,以直接獲取經(jīng)濟回報。然而,這樣的發(fā)展模式會大大消耗這片世代相傳的土地,磨滅祖先們在這片土地上留下的痕跡,最終造成本土社會文化的同質(zhì)化。
“迂回發(fā)展”項目基于景觀譜系理念提出適應(yīng)性生態(tài)旅游框架,以避免上述本土社會文化的同質(zhì)化。項目以位于瑯南塔省的兩個村莊——具有較長特許經(jīng)營史的辛烏多姆村和近期搬遷的坤康村——針對當(dāng)?shù)氐湫偷木湃松鷳B(tài)旅游項目定制了兩套方案。首先開展多維度考察,記錄當(dāng)?shù)厣鐓^(qū)居民生存方式與文化思維的變遷??疾彀l(fā)現(xiàn),這兩個村莊居民的生計模式在過去六年間發(fā)生了巨大的改變,當(dāng)?shù)匚幕瘍r值面臨巨大威脅。隨后通過比較當(dāng)?shù)厝齻€頗受歡迎旅游項目的活動內(nèi)容和運營情況,發(fā)現(xiàn)為期兩天的行程最有助于合理安排游覽時間和活動內(nèi)容,在幫助當(dāng)?shù)鼐用耖_發(fā)和保護(hù)本土價值的同時,也可為游客創(chuàng)造精彩的體驗。研究發(fā)現(xiàn),由于缺乏定期維護(hù),林間步道受坡度、土壤成分、排水性能和氣候條件影響較大。同時,土地使用情況跟隨休耕周期(三年)而變化。最終,本項目提出通過迂回發(fā)展來構(gòu)建本土韌性,串連上述動態(tài)節(jié)點、組織游覽路線。其中,方案一強調(diào)生計間的差異,即“外部差異”:在游覽過程中,游客們被分為兩組,分別體驗不同的生計,而后互相交流分享各自對景觀的看法。方案二專為搬遷安置點設(shè)計,關(guān)注本土價值的延續(xù),即“內(nèi)部相似性”:在游覽中融入民俗文化體驗、歷史情境展示等活動,喚起人們對本土文化身份的認(rèn)同,進(jìn)而更好地展望未來。這兩套方案被分別應(yīng)用于辛烏多姆村和坤康村。本文所提出的適應(yīng)性框架適用于老撾北部的所有村莊,在應(yīng)用時應(yīng)遵循各村莊自身的發(fā)展歷程,以避免社會文化的同質(zhì)化。

Abstract
After two years of sporadic lockdowns, northern Laos has fully reopened to travelers. However, communities have shown indifference to ecotourism recovery that provides ecological services; prioritized alternatives such as rubber concession are diminishing indigenous sociocultural values and turning ancestral soils into exploitative grounds in exchange for economic returns. Disappearance of historical traces may ultimately homogenize communities’ indigenous sociocultural significance. In light of such fragility, Development Detours offers an adaptive framework of landscape genealogies by using two tailored formulas externally and internally. The proposal constructs resilience by detouring development progression, interconnecting nodes of chronicle as a rework of presence. Two villages along the Nam Tha River, namely Sin Oudom and Khon Kham, were selected for their ongoing frictions. While formula one emphasizes “differences” between livelihoods by reconnecting nonlinear spatio-temporality into discursive viewpoints, formula two delineates “collectiveness” by acknowledging myths, traditions, and legacies of practices as a celebration of identities. By utilizing account as a forward-minded approach, history is adapted to the present.
