The Functional Structure Convergence of China's Coastal Ports
sustainability Article The Functional Structure Convergence of China’s Coastal Ports Wei Wang 1,2,3, Chengjin Wang 1,* and Fengjun Jin 1 1 Institute of Geographic Sciences and Natural Resources Research, CAS, Beijing 100101, China; [email protected] (W.W.); [email protected] (F.J.) 2 University of Chinese Academy of Sciences, Beijing 100049, China 3 School of Geography, Beijing Normal University, Beijing 100875, China * Correspondence: [email protected] Received: 6 September 2017; Accepted: 23 November 2017; Published: 28 November 2017 Abstract: Functional structure is an important part of a port system, and can reflect the resource endowments and economic development needs of the hinterland. In this study, we investigated the transportation function of coastal ports in China from the perspective of cargo structure using a similarity coefficient. Our research considered both adjacent ports and hub ports. We found that the transportation function of some adjacent ports was very similar in terms of outbound structure (e.g., Qinhuangdao and Huanghua) and inbound structure (e.g., Huanghua and Tangshan). Ports around Bohai Bay and the port group in the Yangtze River Delta were the most competitive areas in terms of outbound and inbound structure, respectively. The major contributors to port similarity in different regions varied geographically due to the different market demands and cargo supplies. For adjacent ports, the functional convergence of inbound structure was more serious than the outbound. The convergence between hub ports was more serious than between adjacent ports in terms of both outbound and inbound structure. The average similarity coefficients displayed an increasing trend over time. -

Australian Earthquake Engineering Society Conference AEES 2008, Ballarat, Victoria. Special Session on 512 Wenchuan Earthquake Lessons Learnt from the 512 Wenchuan Earthquake: Perception of Seismic Risks Hing-Ho Tsang Research Fellow, Department of Civil Engineering, The University of Hong Kong, Pokfulam Road, Hong Kong, China. Email: [email protected] Abstract On May 12, 2008, a devastating earthquake occurred in Sichuan Province of China depriving tens of thousands of lives and destroying homes of millions of people. In this article, the seismotectonic background and the seismicity of the regions are first introduced. The seismic hazard levels specified in the Chinese Code for Seismic Design of Buildings, GB 50011 – 2001, and issues concerning the perception of earthquake risks and the extensive damage to buildings in the affected regions are discussed. Keywords: Wenchuan Earthquake, Sichuan, China, seismic, hazard, risk, intensity 1. BRIEF BACKGROUND OF THE 512 WENCHUAN EARTHQUAKE At 06:28:01.42 UTC on May 12, 2008, a devastating earthquake occurred at the Wenchuan County in the Sichuan Province of China. On the moment magnitude scale, the earthquake was of Mw = 7.9 according to reports from the United States Geological Survey (USGS). On the surface wave magnitude scale, the earthquake was of Ms = 8.0 according to reports from the China Earthquake Administration (CEA). The epicentre of the earthquake was 80 km west-northwest of the provincial capital city of Chengdu (refer Figure 1(a)). The fault ruptured at a depth of about 19 km. There were over 200 aftershocks with magnitudes greater than 4.0 and 8 aftershocks with magnitude greater than 6.0 occurred in the area afterwards. -

Appendix A A Study of the Haicheng Foreshock Sequence By Lucile Jones, Wang Biquan and Xu Shaoxie (English Translation of a Paper Published in Di Zhen Xue Bao (Journal of Seismology), 1980.) Abstract We have examined the locations and radiation patterns of the foreshocks to the 4 February 1978 Haicheng earthquake. Using four stations, the foreshocks were located relative to a master event. They occurred very close together, no more than 6 kilo meters apart. Nevertheless, there appear to have been too clusters of foreshock activity. The majority of events seem to have occurred in a cluster to the east of the master event along a NNE-SSW trend. Moreover, all eight foreshocks that we could locate and with a magnitude greater than 3.0 occurred in this group. The're also "appears to be a second cluster of foresfiocks located to the northwest of the first. Thus it seems possible that the majority of foreshocks did not occur on the rupture plane of the mainshock, which trends WNW, but on another plane nearly perpendicualr to the mainshock. -

Shear-Wave Velocity–Based Probabilistic and Deterministic Assessment of Seismic Soil Liquefaction Potential
Shear-Wave Velocity–Based Probabilistic and Deterministic Assessment of Seismic Soil Liquefaction Potential R. Kayen, M.ASCE ; R. E. S. Moss, M.ASCE ; E. M. Thompson, A.M.ASCE ; R. B. Seed, M.ASCE ; K. O. Cetin, M.ASCE ; A. Der Kiureghian, M.ASCE ; Y. Tanaka ; and K. Tokimatsu, M.ASCE Abstract: Shear-wave velocity (Vs) offers a means to determine the seismic resistance of soil to liquefaction by a fundamental soil property. This paper presents the results of an 11-year international project to gather new Vs site data and develop probabilistic correlations for seismic soil liquefaction occurrence. Toward that objective, shear-wave velocity test sites were identified, and measurements made for 301 new liquefaction field case histories in China, Japan, Taiwan, Greece, and the United States over a decade. The majority of these new case histories reoccupy those previously investigated by penetration testing. These new data are combined with previously published case histories to build a global catalog of 422 case histories of Vs liquefaction performance. Bayesian regression and structural reliability methods facilitate a probabilistic treatment of the Vs catalog for performance-based engineering applications. Where possible, uncertainties of the variables comprising both the seismic demand and the soil capacity were estimated and included in the analysis, resulting in greatly reduced overall model uncertainty relative to previous studies. The presented data set and probabilistic analysis also help resolve the ancillary issues of adjustment for soil fines content and magnitude scaling factors. Introduction correlating more directly with relative density, which has a strong effect on the cyclic behavior of saturated soil (Idriss and fi Of the several eld techniques routinely used to assess triggering of Boulanger 2008). -
Active Tectonics and Intracontinental Earthquakes in China: the Kinematics and Geodynamics
The Geological Society of America Special Paper 425 2007 Active tectonics and intracontinental earthquakes in China: The kinematics and geodynamics Mian Liu Youqing Yang Department of Geological Sciences, University of Missouri, Columbia, Missouri 65211, USA Zhengkang Shen State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China Shimin Wang Department of Geological Sciences, University of Missouri, Columbia, Missouri 65211, USA Min Wang Institute of Earthquake Science, China Earthquake Administration, Beijing 100036, China Yongge Wan School of Disaster Prevention Techniques, Yanjiao, Beijing 101601, China ABSTRACT China is a country of intense intracontinental seismicity. Most earthquakes in west- ern China occur within the diffuse Indo-Eurasian plate-boundary zone, which extends thousands of kilometers into Asia. Earthquakes in eastern China mainly occur within the North China block, which is part of the Archean Sino-Korean craton that has been thermally rejuvenated since late Mesozoic. Here, we summarize neotectonic and geo- detic results of crustal kinematics and explore their implications for geodynamics and seismicity using numerical modeling. Quaternary fault movements and global position- ing system (GPS) measurements indicate a strong infl uence of the Indo-Asian colli- sion on crustal motion in continental China. Using a spherical three-dimensional (3-D) fi nite-element model, we show that the effects of the collisional plate-boundary force are largely limited to western China, whereas gravitational spreading of the Tibetan Plateau has a broad impact on crustal deformation in much of Asia. The intense seis- micity in the North China block, and the lack of seismicity in the South China block, may be explained primarily by the tectonic boundary conditions that produce high devi- atoric stresses within the North China block but allow the South China block to move coherently as a rigid block. -

Under the call of sustainable development, it is of great significance to evaluate the economic, social, and ecological (ESE) impact of transportation network in BTH urban agglomeration for promoting the sustainable development of transportation ESE in BTH urban agglomeration. In this paper, 12 indicators in the field of transportation are selected to build the evaluation index system of ESE effects of transportation network in BTH urban agglomeration. By using entropy weight TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) model and the Jenks natural breaks classification method, the ESE impacts of transportation network in 13 cities of BTH from 2013 to Citation: Zhang, L.; Zhang, X.; Yuan, 2017 are analyzed from the temporal and spatial dimensions. -
Chinese Experience with Post-Natural-Disaster Reconstruction
CHINESE EXPERIENCE WITH POST-NATURAL-DISASTER RECONSTRUCTION Ye Yaoxian* China Architectural Design and Research Group Abstract The paper begins with a discussion of the facts about natural disasters with emphasis on both floods and earthquakes that happened in China, and then shifting the focus from the lessons to be learnt from reconstruction to improvement of reconstruction strategies following a natural disaster. This includes policy development, decision making technology, and evaluation models and etc. The paper concludes with a summary of reconstruction experiences learned from the practices in past decades in China. Post-Natural-Disaster; reconstruction; China INTRODUCTION At the beginning of a millennium, it is appropriate but also necessary to look back upon the events happened in China and to see what lessons and prognoses concerning post-natural-disaster reconstruction can be derived from them for the future. The Government of People’s Republic of China, in response to various natural disasters that occurred in the country after its founding in 1949, particularly the 1976 Tangshan Earthquake which caused 242,000 deaths and the 1991 Anhui and Jiangsu flood which caused 5,000 deaths and 77.9 billion RMB of direct economic losses, noted the importance of significantly improved reconstruction strategies. Reconstruction following a natural disaster is a complicated problem concerning social, economical, cultural, environmental, psychological, and technological aspects. However, for developing countries or regions, it is a good opportunity to change its original economy development model and to push the urban and rural renewal forward. Therefore, improved strategies and reconstruction plans are the key to accelerate the reconstruction process and to improve human settlement environment. -
Air Pollution in China: Mapping of Concentrations and Sources
Air Pollution in China: Mapping of Concentrations and Sources Robert A. Rohde1, Richard A. Muller2 Abstract China has recently made available hourly air pollution data from over 1500 sites, including airborne particulate matter (PM), SO2, NO2, and O3. We apply Kriging interpolation to four months of data to derive pollution maps for eastern China. Consistent with prior findings, the greatest pollution occurs in the east, but significant levels are widespread across northern and central China and are not limited to major cities or geologic basins. Sources of pollution are widespread, but are particularly intense in a northeast corridor that extends from near Shanghai to north of Beijing. During our analysis period, 92% of the population of China experienced >120 hours of unhealthy air (US EPA standard), and 38% experienced average concentrations 3 that were unhealthy. China’s population-weighted average exposure to PM2.5 was 52 µg/m . The observed air pollution is calculated to contribute to 1.6 million deaths/year in China [0.7–2.2 million deaths/year at 95% confidence], roughly 17% of all deaths in China. Introduction Air pollution is a problem for much of the developing world and is believed to kill more people worldwide than AIDS, malaria, breast cancer, or tuberculosis (1-4). Airborne particulate matter (PM) is especially detrimental to health (5-8), and has previously been estimated to cause between 3 and 7 million deaths every year, primarily by creating or worsening cardiorespiratory disease (2-4,6,7). Particulate sources include electric power plants, industrial facilities, automobiles, biomass burning, and fossil fuels used in homes and factories for heating. -

As a result, the land price in an urban area is not only affected by the city’s own factors, but also by its interaction with nearby cities. Understanding the characteristics, types, and patterns of urban interaction is of critical importance in regulating the land market and promoting coordinated regional development. In this study, we integrated a gravity model with an improved Voronoi diagram model to investigate the gravitational characteristics, types of action, gravitational patterns, and problems of land market development in the Beijing-Tianjin-Hebei urban agglomeration region based on social, economic, transportation, and comprehensive land-price data from 2017. The results showed that the gravitational value of land prices for Beijing, Tianjin, Langfang, and Tangshan cities (11.24–63.35) is significantly higher than that for other cities (0–6.09). The gravitational structures are closely connected for cities around Beijing and Tianjin, but loosely connected for peripheral cities. -
Chapter 1: Civil Buildings
1 CHAPTER 1: CIVIL BUILDINGS A SURVEY OF DAMAGE TO CIVIL BUILDINGS Xia Jingqian1, Tong Enchong2 and Zhou Bingzhang3 The Beijing-Tianjin-Tangshan region is situated in the northeastern part of the North China plain and is one of the densely populated and developed regions. During the Tangshan earth- quake civil buildings in this region suffered very severe damage; the damage to and collapse of many residential buildings resulted in great loss of life and property. I. Building Structures Before the Earthquake The Tangshan region includes Tangshan city, Qinhuangdao city and twelve counties, i.e. Fengrun, Fengnan, Luanxian, Luannan, Leting, Changli, Funing, Lulong, Qian-an, Qian-xi, Zunhua and Yutian, and the Baigezhuang Farming Reclamation area. The area of the Tangshan region is 16.5 thousand square kilometers. In Tangshan the area of civil buildings including self- constructed residences was 11.692 million square meters, being 73.7% of the total area of the buildings. The civil buildings included residential buildings of 8.941 million square meters, office buildings of 0.807 million square meters, school buildings of 0.463 million square meters, hospital buildings of 0.225 million square meters and other buildings (store and public buildings, etc.) of 1.256 million square meters. The civil buildings in Tangshan were mainly located in the city and east mining area. Besides, there were 5.483 million square meters of rural civil build- ings in the suburbs of Tangshan city. In other cities, counties and farming reclamation area in the Tangshan area there were 4.969 million units of rural civil building and the total area was about 8.076 million square meters of civil buildings in cities and towns (Table 1).
