城市再造與韌性提升:以綠色基礎設施為導向的閑置土地再利用的經濟績效評估
Resilience Through Regeration: The Economics of Repurposing Vacant Land With Green Infrastructure
作者:蓋倫·紐曼,黎東瑩,朱芮,任丁鼎 Galen NEWMAN, LI Dongying, ZHU Rui, REN Dingding
摘要
閑置土地的增多使得很多原本就遭受洪水困擾的城市的生態和社會肌理變得更加碎片化。在談及閑置土地再利用時,重建往往被視為首要目標,但除此之外,它們本身也具有潛在的生態和水文價值。在高洪水風險社區中,與其盲目追求以發展建設為目標的閑置土地再造措施,更重要的是要在新增開發用地和建設綠色基礎設施之間尋求平衡,以削減雨水徑流、降低洪水影響,由此,我們提出了“通過再造提升韌性”的規劃設計理念。以美國德克薩斯州休斯頓市的三個邊緣化社區的規劃設計實踐為例,本文使用景觀績效評估方法評價綠色基礎設施再利用項目的經濟和水文影響。這三個規劃設計場地都面臨著閑置土地過剩和雨洪問題。評估結果表明,使用綠色基礎設施實現閑置土地再利用將使得雨洪風險不斷降低,(與傳統開發模式相比)短期內前期投入成本增加,但長期經濟回報顯著提升。

Abstract
Many urban areas affected by flood disasters are also becoming increasingly ecologically and socially fragmented due to the accumulation of vacant properties. While redevelopment is often viewed as the primary objective in regenerating vacant properties, they can also potentially provide ecological and hydrological land uses. Rather than chasing development-based incentives for regenerating vacant lots in high flood-risk communities, a balance should be sought between new developmental land uses and green infrastructure to help counteract stormwater runoff and flood effects, or “Resilience through Regeneration.” This paper uses landscape performance measures to evaluate the economic and hydrologic performance of green infrastructure regeneration projects for three marginalized neighborhoods in Houston, Texas, USA. Each project site is characterized by excessive vacant lots and flood issues. Results suggest that, when using green infrastructure to regenerate vacant properties, 1) flood risk continually decreases, 2) upfront economic costs increase in the short term (when compared to conventional development), and 3) the long-term economic return on investment is much higher.

Abstract
In the context of China’s current policy-oriented Rural Rejuvenation movement, through case studies, the paper reviews protection and renewal strategies and approaches of traditional rural buildings, ranging from preservation and reshaping of traditional architectural formal elements and group characteristics, contemporary interpretation and application of traditional construction techniques, to introduction of semi-industrialized construction modes and new structural organizing approaches. Based on theoretical and technical studies of sustainability, this paper puts forward a new semi-industrialized intervention mode, called “micro-renewal,” which is more applicable for renewal practices in rural China. Finally, illustrating with an authentic micro-renewal case, the “Embedded House” in Dainan Town in Xinghua, Jiangsu Province, the paper demonstrates that this new semi-industrialized intervention offers a paradigm to strategies, techniques, and alternatives for future architectural renewal and protection in rural China.

生態文明時期的城市競爭力提升與城市治理探索
Exploration on Strengthening City Competitiveness and Improving Urban Governance in the Age of Ecological Civilization
作者:葉裕民 YE Yumin
摘要
在本采訪中,受訪人葉裕民首先對“城市經濟學”“城市經濟”“產業結構升級”等常見的經濟學概念進行了厘清,并指出當前中國城鎮化要以人民得到最廣泛、最大幅度的發展為核心任務,積累人力資本,優化勞動力結構,從而支撐產業結構持續升級,培育新動能。她同時認為,在生態文明時期,城市規劃者和設計者的職責是通過創造包容性的城市更新和城市設計,幫助城市提高競爭力。她繼而強調,中國的大部制改革符合時代的需求,也是提高國家未來整體競爭力、維護城市公共利益的必然選擇。最后,葉裕民闡明了自上而下的管理模式與自下而上的治理模式的適用范疇,認為目前中國政府和社會資本合作項目出現的種種問題,根源都在于合作雙方缺乏誠信,而根本的解決途徑之一則是建立完善的誠信制度,以明確雙方的信用權責。

Abstract
In this interview, Ye Yumin, the interviewee, first clarifies basic concepts of Economics such as Urban Economics, a city’s economy, and industrial structure upgrading, and points out that, to most Chinese cities, the failure of industrial structure upgrading and new driving force fostering largely is due to their inadequate labor force structure. She argues that today’s primary task of China's urbanization is to ensure people’s overall well-being, encourage their activity and cultivate talents, accumulating human capital to support the continuous upgrading of industrial structure and developing new driving forces. Ye further argues that, in the age of Ecological Civilization, urban planners and designers play an important role in strengthening cities’ competitiveness with inclusive renewal and design concepts, while highlighting that China’s new reform of a Super-Ministry System is in line with contemporary needs to improve the overall competitiveness of the country in the future and to safeguard the public interests. Finally, by recognizing the application scopes of the both top-down Management mode and bottom-up Governance mode, Ye articulates that all problems in China’s PPP cases are caused by the poor credibility of both public and private parties, and a sound credibility system and mechanism is urgently required, which would define duties of both parties.

資產管理視角下的景觀設計
Landscape Design as an Asset Management
作者:林瑋 LIN Wei
摘要
景觀是人類經濟活動的產物,亦可被視作一種資產,其形成受限于生產力水平與生產關系。無論是自持、銷售物業,還是政府公共項目,設計都需要考慮租金回報、公眾滿意等全生命周期利益流入。本文提供了以資產管理的思路理解景觀的獨特視角,并指出了在從設計到使用的全生命周期中,資產管理所扮演的角色——其介入有助于基于不同階段和不同群體的利益對設計方案進行平衡與協調。除借助資產管理方的幫助外,設計師也應加強產品思維與用戶思維,通過輪崗、跨部門聯席會議、項目制組織等機制掌握通識與交叉業務知識,藉由早期全局介入和使用后評估及時評估運營結果,以復盤教訓、改良成果。

Abstract
Landscape is a product of economic activities and an asset associated with a society’s productivity levels and the relations of production. Despite the range of projects —self-owned, for-sale, or public infrastructure — that designers undertake, life-cycle benefits such as rental returns and public satisfaction should always be considered. By interpreting landscape design as an asset management, this article highlights the third-party role of asset managers who coordinate the benefits of all stakeholders at different stages through negotiation of design options. Designers are also expected to have a product and user thinking, acquire general and interdisciplinary knowledge of certain businesses through role rotations, cross-department meetings, and diverse project teams to improve design proposals, and strengthen mechanisms of pre-occupancy engagement and post-occupancy evaluation.

摘要
景觀具有多種經濟價值。然而,本次采訪受訪人烏多·韋拉赫爾指出,全球經濟發展的大多數領導力量都低估了景觀所擁有的眾多非經濟價值。他認為,公眾對于景觀和環境價值的認知在某種程度上取決于國家的發展階段,并希望發展中國家不要重復發達國家以環境破壞為代價的發展道路。他繼而強調,盡管景觀效益難以進行經濟核算,但景觀設計師應當超越經濟計算的語境來討論景觀的環境價值。最后,韋拉赫爾認為當前的景觀設計學院校教育對景觀的經濟考量尚不夠重視,但設計必須充滿熱情,才能吸引并感染人們,這樣景觀設計師才有機會說服人們為環境改善而投資。

Abstract
Landscape has various economic values. However, Udo Weilacher, the interviewee, argues that most drivers of the global economic development do underestimate the wide range of non-economic values of landscape. He points out that public awareness on the values of landscape and environment somehow depends on the societal developing phase of a country, and hopes that developing countries would not go through the same developments that caused irreversible environmental damage, as what most developed countries did. Weilacher further reflects that the benefits of landscape cannot be economically calculated and landscape architects need to discuss environmental values beyond economic calculation. Finally, he argues that in the current college education of Landscape Architecture, economic aspects of landscape have not been emphasized enough, and landscape design has to be enthusiastic to overwhelm and fascinate people in order to persuade them to invest for environmental improvement.

從直覺驅動到產品驅動:設計價值觀及其責任的轉變
From Intuition-Driven to Product-Driven Design: Changes in Design Values and Responsibilities
作者:朱勝萱 ZHU Shengxuan
摘要
在本次采訪中,受訪人朱勝萱結合自身從業經歷,從建筑師、景觀設計師、企業家等不同視角闡述了對“設計”的內涵價值及社會責任的理解。他認為,設計的使命是協調各方利益,盡可能創造惠及整個社會的公共價值,以產品為載體的商業思維則有助于傳達設計思維所蘊含的公益價值觀。基于這種認識,他創立了獨特的“設計、建造、運管一體化”模式,以產品化視角傳達設計理念、傳播獨特設計價值觀,以創造更大的社會影響力。對于當前中國亟待實現的鄉村振興,他認為應以多樣化、面向未來的視角分析鄉村問題,并指出制度是阻礙農民從鄉村開發建設中獲得更多經濟收益的重要因素。

Thoughts on Synergetic Development of Watershed Management and Regional Economy
作者:朱慶平 ZHU Qingping
摘要
受訪人朱慶平為中國流域治理專家,在本次采訪中,他以中國流域管理模式與治水理念的變化作為切入點,強調流域管理需綜合考慮公共資源、基礎設施建設、生態系統、歷史文化、人口資源等因素;繼而聚焦于黃河治理,闡釋了河流演變與城市發展之間的相互作用與影響,在反思治水思想的同時,指出當下正是黃河下游沿線城市發展的大好機遇,并提出了建立“黃河國家生態文化帶”這一構想;最后,朱慶平指出,流域治理需要多行業、多學科、跨地區、跨部門協作,并應當重視公眾參與和社會維護在流域管理中的重要意義,以及通過在未來建立“智慧水務/水利”大數據綜合集成平臺,實現水資源供給與水安全保障的智能化、協調化發展。

Abstract
Zhu Qingping, the interviewee, is a prominent expert in China’s watershed management. Starting with the modes of China’s watershed management and the changes of water management philosophy, Zhu emphasizes that watershed management often involves various factors, including public resources, infrastructure construction, ecosystems, historical and cultural traditions, and population, all of which shall be taken into consideration as a whole. The interview then goes to the management of the Yellow River Basin, where Zhu explains the impacts between river flows and urban development, suggests a great opportunity for development the cities in the lower reaches of Yellow River Basin have, and proposes an idea of building a national ecological and cultural belt along the river. He further argues that watershed management requires collaborations across industries, disciplines, and administrative regions and divisions. He also believes that public engagement and maintenance plays an important role in watershed management and an intelligent water / watershed management system needs to be established by networking integrated big-data platforms to facilitate a more intelligent and coordinated water resource management while better ensuring water security at varied scales.

Abstract
While rapid spread of urbanization brings dramatical economic growth to major cities worldwide, they are relentlessly eating up green spaces and farmlands essential to the ecosystem and environmental health, risking the common benefits for all lives with inbalanced development and putting a burden on contemporary Landscape Architecture to coordinate ecology and aesthetic with economy. By integrating design aesthetic and engineering efficiency, Fudao, a first-of-its-kind elevated steel walkway system in Fuzhou, China, addresses this challenge successfully by opening up a once desolated mountain area to the public with a minimum environmental disturbance achieved by an innovative design approach, which gains international attention.

Abstract
Offering an alternative planning and design strategy of renewals of low-density urban villages, this research estimates potentials of increasing a city’s accommodation capacity of low-skilled labor force through economic approaches like the Game Theories. A design idea of creating an “arrival city” is proposed in the prototypical study on the renewal of the Ganjiazhai Community, a typical urban village in Xi’an City, Shaanxi Province. Developing spatial patterns through a series of evidence-based deductions and estimations, this research forms a node-axis framework of urban planning and design that allows for an adaptive combination of spatial modules and encourages spatial sharing, which might shine a reference for future planning and design of urban villages in Chinese cities.

縱向維度:本地生態與垂直經濟
Altitudes: Local Ecologies and Vertical Economies
作者:弗朗西斯科·加羅法洛 Francesco GAROFALO
摘要
“塞爾瓦中央林區”是秘魯境內一個由高海拔森林構成的鄉村地區,當地經濟主要依賴咖啡生產。單一種植對該地區的影響包括由仰賴單一商品造成的經濟脆弱這樣的顯性影響,以及當地社區多元文化與傳統喪失這樣的隱性影響。在該地區咖啡遠銷全球的同時,當地農業模式正因氣候變化發生著轉變。
除了介紹“縱向維度”方案的具體策略,本文亦探討了如何對氣候變化進行可視化呈現、反思供應鏈現狀,以及對作為垂直經濟的在地景觀進行解讀等多元嘗試,在突破咖啡單一種植模式的同時,力求為建立可(部分)自給自足的新社區創造條件。

Abstract
“Selva Central” is a rural area of Peru defined by high-altitude forest, whose economy is largely dependent on the coffee production. The effects of monoculture are both tangible and intangible, ranging from a weak single-commodity economy to the loss of the multifaceted cultural expertise and traditions of local communities. The area, in fact, produces coffee for global exportation, while is suffering shifting local agricultural patterns due to climate change.
This article argues while unfolding “Altitudes” strategic project, how visualizing climate change, rethinking the supply-chain, and understanding the local landscape as a vertical economy can highlight opportunities of moving beyond the monoculture of coffee, creating the conditions for newly (partially) self-sufficient local communities.

摘要
包括煤礦開采在內的資源開發推動了20世紀的工業增長,同時也帶來了嚴重的環境退化和城市擴張問題。西里西亞是波蘭南部的煤礦開采重鎮,目前正在進行后開采時代的經濟轉型。二氧化硫排放和重金屬沉積改變了這里的土壤酸堿度,導致該地區無法開展農業活動,而地勢沉降和煤渣堆積則改變了當地地貌,導致地面溝壑縱橫。隨著時間的推移,地面出現水塘,森林開始生長。西里西亞森林是煤礦開采時代的印記與延續。
森林經常標示著地區發展的邊界,承載著保護主義的議題,且殘留著工業化進程帶來的創傷。“公民的森林”項目將西里西亞森林作為一個新的中心,其尺度及復雜性使其能夠應對后開采時代城市化進程帶來的挑戰。

Abstract
Industrial growth during the twentieth century, fueled by economies of extraction like coal mining, has produced severe environmental degradation and uniquely dispersed metropolitan areas. Silesia, a region of agglomerated mining towns in Southern Poland, is transitioning to a post-extraction economy. Sulfur dioxide emissions and deposits of heavy metals altered the acidity of the land, making farming impossible. Terrain subsidence and slag heaps transformed the topography, forming new valleys and mountains. Over time, surface water bodies appeared, and a new forest grew. The Silesian forests remain a reflection, and also extension, of an extractive and extracted time.
As forests often demarcate the boundaries of growth, embody narratives of preservationism, and retain the trauma of industrial processes, the Civic Forest addresses the forests of Silesia as a new “center,” one that is capable through their scale and complexity to confront the current challenges and ambitions of the post-extraction metropolis.
