Climate change and China’s mega urban regions

Chaolin GU, Sunsheng HAN

《结构与土木工程前沿（英文）》 2010年 第4卷 第4期   页码 418-430 doi: 10.1007/s11709-010-0075-5

摘要： China’s mega urban regions are focal points of economic development and environmental concerns. This paper positions four mega urban regions (i.e., the Yangtze River Delta, the Pearl River Delta, the Bohai Bay Area, and the South-eastern Fujian Province) along China’s coast into the national economy and elaborates their development challenges and planning innovations. Mega urban regions in China are spatial consequences of rapid economic transition. They deserve close scrutiny and demands for innovative planning responses in order to maintain their key role in driving economic growth but limiting their greenhouse gas emission.

Zhaoheng GONG, Zijuan LAN, Lian XUE, Liwu ZENG, Lingyan HE, Xiaofeng HUANG

《环境科学与工程前沿（英文）》 2012年 第6卷 第5期   页码 725-733 doi: 10.1007/s11783-012-0441-8

摘要： Submicron aerosol particles (with aerodynamic diameters less than 1 μm, PM ) were sampled and measured in Heshan, an urban outflow site of Guangzhou megacity in Pearl River Delta in South China, using an Aerodyne High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) in November 2010 during 2010 Guangzhou Asian Games. The mean PM mass concentration measured was 47.9±17.0 μg·m during the campaign, with organic aerosol (OA) and sulfate being the two dominant species, accounting for 36.3% and 20.9% of the total mass, respectively, followed by black carbon (17.1%, measured by an aethalometer), nitrate (12.9%), ammonium (9.6%) and chloride (3.1%). The average size distributions of the species (except black carbon) were dominated by an accumulation mode peaking at ~550 nm. Calculations based on high-resolution organic mass spectrum showed that, C, H, O and N on average contributed 58.1%, 7.3%, 30.7%, and 3.9% to the total organic mass, respectively. The average ratio of organic mass over organic carbon mass (OM/OC) was 1.73±0.08. Four components of OA were identified by the Positive Matrix Factorization (PMF) analysis, including a hydrocarbon-like (HOA), a biomass burning (BBOA) and two oxygenated (SV-OOA and LV-OOA) organic aerosol components, which on average accounted for 18.0%, 14.3%, 28.8% and 38.9% of the total organic mass, respectively.

Region-gridding recycling of bulk organic waste: Emerging views based on coordinated urban and rural

Wenbing Tan, Dongyu Cui, Xiaohui Zhang, Beidou Xi

《环境科学与工程前沿（英文）》 2020年 第14卷 第6期 doi: 10.1007/s11783-020-1291-4

摘要： Abstract Bulk organic waste (BOW) has a large output in China. The improper disposal of BOW will not only bring serious environmental pollution, but also cause waste of biomass resources. The viewpoint proposes a region-gridding recycling management system of BOW that highlights the coordinated development of environmental, agricultural and energy elements in urban and rural areas. The viewpoint aims to drive the upstream and downstream industrial chains of BOW treatments, avoid the repeated construction of resource facilities, guide the upgrading of resource-based technologies, promote the professionalization of farmers, and thus built the high-quality modern agricultural recycling industrial park based on system management.

Zheming LIU, Liangyan WANG, Zhaohan SHENG, Xinglin GAO

《工程管理前沿（英文）》 2018年 第5卷 第1期   页码 98-108 doi: 10.15302/J-FEM-2018084

摘要： Ecological compensation plays an important role in implementing the social responsibility of infrastructure mega-projects. Based on the results of a field study, an in-depth interview, and archive data, this paper introduces the ecological compensation for (the Indo-Pacific humpbacked dolphin) during the construction of the Hong Kong-Zhuhai-Macao Bridge. It studies the concrete measures, decision-making processes, and organizational collaboration of the ecological compensation, using the method of a case study. The present study not only enriches our understanding of the ecological compensation practice during the construction of infrastructure mega-projects, but also extends the literature on the social responsibility of infrastructure mega-projects. This sheds light on the protection of the environment as well as biodiversity in the construction of future infrastructure mega-projects.

Silk Roads for the 21st Century: Engineering Mega-Infrastructure for Development and Sustainability

Tony Marjoram

《工程管理前沿（英文）》 2016年 第3卷 第3期   页码 187-196 doi: 10.15302/J-FEM-2016038

摘要： Infrastructure facilitates the movement of people, the production and distribution of goods and services, and underpins development. Infrastructure is expensive and long-lasting, and needs long-term policy, planning and management, in terms of design, construction, operation and maintenance. Infrastructure relates particularly to engineering and technology. All technological change brings economic, social, cultural and environmental change, planned and unpredicted. Mega levels of technology bring mega levels of change, effects and impacts. Mega infrastructure such as the Silk Road Economic Belt and 21st Century Maritime Silk Road, the “One Belt, One Road” (OBOR) initiative, announced by President Xi Jinping in 2013, will require equally mega policy, planning and management. This paper will discuss policy, planning and management issues relating to mega infrastructure and the OBOR initiative, with particular reference to energy, communications, transportation, health, emergency preparedness and response, and less predictable areas of change, for example in disease prevention and control, within the overall need for economic, environmental and ecological sustainability. The paper will discuss associated needs for education, training and capacity building in engineering. The paper will also refer to lessons learnt from the original Silk Road in the context of the development of civilizations and intercultural dialogue through the transfer of goods, services, technologies, ideas, knowledge, customs, cultures and philosophies, less predictable and unwanted transfers, for example of disease, and the need for awareness, policy, planning and management of such wider issues.

Mankind and Mega-projects

Naomi J. Brookes

《工程管理前沿（英文）》 2014年 第1卷 第3期   页码 241-245 doi: 10.15302/J-FEM-2014033

摘要： Throughout history mankind has sought to improve its economic and even its spiritual development through the creation of gargantuan and awe-inspiring infrastructure projects. The twenty-first century has seen the rapid growth of the use of this type of project in providing society’s needs: such projects are widely referred to as “mega-projects”. Mega-projects are extremely large-scale infrastructure projects typically costing more than $1 billion. Mega-projects include power-plant (conventional, nuclear or renewable), oil and gas extraction and processing projects and transport projects such as highways and tunnels, bridges, railways, seaports and even cultural events such as the Olympics. Mega-projects are united by their extreme complexity (both in technical and human terms) and by a long record of poor delivery. What to do in the face of this dilemma is a question that is still being asked by mega-project practitioners and academics alike. This paper presents the unique work of the MEGAPROJECT COST Action which brings together a multi-disciplinary network of over 80 researchers from 24 countries to respond to this dilemma. Mega-project’s aim involves capturing the existing performance of large infrastructural mega-projects and understanding how their delivery can be improved. In order to do this, the investigation has gathered together the MEGAPROJECT Portfolio. The Portfolio contains meta-data on a wide range of mega-projects from across countries and sectors and acts as a firm empirical foundation for the investigation’s activities. Having assembled the MEGAPROJECT Portfolio, this paper shows how analyzing the Portfolio shatters myths of mega-project management and identifies new areas of fruitful investigation. Mega-project’s findings downplay the importance of formal project management tools and techniques in insuring successful delivery. Instead mega-project highlights the need to concentrate on the impact of financing on project governance, the technical modularization of the project and the devastating roles that eternal stakeholders can have on mega-project delivery. Most importantly, it discusses how we can effectively learn across mega-projects in order to maximize their value to their stakeholders and to society as a whole.

Adaptability evolution of financing systems of mega projects

Xue YAN, Longmiao GAO, Huimin LIU

《工程管理前沿（英文）》 2021年 第8卷 第2期   页码 258-270 doi: 10.1007/s42524-019-0066-8

摘要： Mega projects require large funding, which often reaches tens or even hundreds of billions of yuan. In the state-oriented financing system, the huge fund gap has generally become an important factor restricting the development of mega projects worldwide. Since the 1980s, China’s long-span bridge projects have developed rapidly as typical mega projects as their financing systems have also undergone a series of changes and shown a high adaptability to complexity. However, the existing literature based on the perspective of evolution lacks focus on the complexity of mega project financing systems and its causes. Therefore, the complexity of the financing methods employed in the financing systems for China’s long-span bridges is analyzed in this work from the dimensions of time and regions through investigation and interviews. On the basis of the results and complex adaptive systems theory, the causes of the complexity are further explored in terms of the clustering effects of financing subjects and the deep uncertainty of financing environments. Then, the evolution rules of financing systems of mega projects are established from the aspect of financing subjects, financing environments, and financing methods. The research results can enrich decision-makers’ understanding of the essential attributes and formation mechanism of the financing systems of mega projects and provide powerful support for decision-making in financing.

摘要：

The Sino-German research collaboration project, “Recycling of organic residues from agricultural and municipal origin in China” (2008–2012), comprising different interdisciplinary research groups, and also German small and medium-sized enterprises, aimed at developing integrated strategies and solutions for the recycling of organic residues in China. In an intensive crop-livestock agricultural region in the Shunyi District of Beijing, five typical cropping systems were investigated. The research was conducted in the form of analyses of phosphorus (P) in soil, plants, animal feed, animal products, manures, mineral and organic fertilizers and the derivation of the corresponding nutrient balances and P flows. The mean annual P balance surplus was 492 kg·ha ·yr P for the vegetable production system, significantly higher ( <0.05) than that for orchards (130 kg·ha ·yr P) and cereal crops (83 kg·ha ·yr P). Plant-available P (Olsen-P) concentrations of topsoils (0–20 cm) had good correlations with the amounts of P applied (from mineral and organic sources). Compared to results from the Second Chinese National Soil Survey of 1981, mean concentrations of available P in soils of 19 plots investigated in Shunyi District increased 10-fold (from 7.3 to 60 mg·kg ) from 1981 to 2009. On average, the critical limit for Olsen-P concentrations (>30 mg·kg ) that can lead to increased risk of P loss was exceeded in all five cropping systems. With feed additives, the “natural background value” (Chinese Environmental Quality Standard for Soils) of copper and zinc in topsoils was exceeded at several sites. Screening for several substances in the veterinary antibiotic classes of sulfonamides, tetracyclines, and fluoroquinolones revealed widespread topsoil contamination. Calculated livestock densities were 10.6 livestock units per ha arable land in 2007. Animal husbandry is increasingly conducted in large operations, making traditional ways of reuse difficult to apply. Comparing three management systems for treatment of organic residues from a pig farm via aerobic (composting) or anaerobic (biogas) treatment in a life cycle assessment, the resulting cropland demand for a sustainable land application of biogas effluent varied between 139 and 288 ha·yr , well above the cropland area owned by the farm (10 ha). The mismatch problems in the above context between business-as-usual and improving performance are framed and discussed as (1) the mismatch between centralized animal husbandry and smallholder farming, (2) the mismatch between livestock density and cropland, (3) nutrient (including P) recycling and increasing organic matter content versus energy production, (4) subsidies for compost production and biogas, as well as (5) advances in the regulatory framework in China.

《工程管理前沿（英文）》 2018年 第5卷 第1期   页码 88-97 doi: 10.15302/J-FEM-2018077

摘要： In this paper the Hong Kong-Zhuhai-Macao Bridge project is taken as a case to analyze supplier development in infrastructure mega-projects. Compared with manufacturing industry, the characteristics of supplier development in infrastructure mega-projects is analyzed in term of development motives, supplier selection, quality management, production mode, owner participation and risks. The critical factors influencing the construction supplier development are identified, which include incentives, collaboration, future market, trust and bilateral communication. Furthermore, focusing on the incentives for the supplier’s product quality and production capacity improvement, decision-making framework models are proposed to design the incentive mechanisms.

摘要： Infrastructure mega-project (IMP) innovation is a complex process characterized by highly diverse innovators, a dynamic life-cycle, and stickiness of innovation knowledge. The IMP’s innovation network can be easily broken due to the fact that the network involves many different innovators across different industries and different projects. Further reasons for the fragility of the IMP’s innovation network are the dynamics of the IMP life-cycle, the diversity of the IMP’s innovative entities, the uniqueness of each IMP, and the temporary nature of each IMP’s organizations. The formed by the breaking of an IMP’s innovation network can stifle and harm innovation performance. Drawing from the knowledge-based view as well as innovation network theory, our research identifies the heterogeneous characte- ristics of IMP innovation. We propose a framework to analyze the formation mechanism of the IMP innovation island from three dimensions—the , the , and the . We look at the Hong Kong-Zhuhai-Macao Bridge project to elaborate the innovation island concept that negatively impacts IMP innovation. We also offer theoretical implications regarding the broader question of how IMPs can manage their innovation in practice.

Smart construction site in mega construction projects: A case study on island tunneling project of Hong

Hongtao ZHOU, Hongwei WANG, Wei ZENG

《工程管理前沿（英文）》 2018年 第5卷 第1期   页码 78-87 doi: 10.15302/J-FEM-2018075

摘要： The construction sites of mega construction projects (MCP) often have numerous participants with interfacing work within a highly complex system. It is critical how to realize collaborative work and information sharing among such participants. The information and communication technologies (ICTs) provides a technical guarantee for solving this problem. Existing research has been achieved the partial processes digitization of construction site, but certain problems still exist: 1)information perception of the construction site is passive. 2) common collaboration and coordination problems in the construction industry have not been addressed. The emerging trends of ICTs have resulted in the integration of various computer technologies such as CPS, BIM, big data, and cloud computing into construction process, which would changes behavioral and management mode of construction sites. These new ICTs have been applied successfully in MCP, in particular, Hong Kong-Zhuhai-Macao Bridge project. A new management mode of construction sites is inspired by these case. In this paper, a new management mode of construction site for MCP has been proposed, namely, smart construction site. The ultimate goal of smart construction site is to accomplish safe, efficient and high-quality construction. This study put forward the conceptual framework for smart construction site, and have identified three key elements of smart construction site, including information support platform, collaboration work, and intelligent construction management. A case study on Hong Kong-Zhuhai-Macao Bridge project work as an evidence to support the practicability of the proposed mode. Significant contributions of this study is to propose a new management mode for MCP in construction industry, which would enrich the body of knowledge or the construction management community. Future research should be dedicated to further explore the potential of smart construction site in MCP management.
