  • A Survey of Marine Coastal Litters Around Zhoushan Island, China and Their Impacts
    Journal of Marine Science and Engineering Article A Survey of Marine Coastal Litters around Zhoushan Island, China and Their Impacts Xuehua Ma 1, Yi Zhou 1, Luyi Yang 1 and Jianfeng Tong 1,2,3,* 1 College of Marine Science, Shanghai Ocean University, Shanghai 201306, China; [email protected] (X.M.); [email protected] (Y.Z.); [email protected] (L.Y.) 2 National Engineering Research Center for Oceanic Fisheries, Shanghai 201306, China 3 Experimental Teaching Demonstration Center for Marine Science and Technology, Shanghai Ocean University, Shanghai 201306, China * Correspondence: [email protected] Abstract: Rapid development of the economy increased marine litter around Zhoushan Island. Social- ecological scenario studies can help to develop strategies to adapt to such change. To investigate the present situation of marine litter pollution, a stratified random sampling (StRS) method was applied to survey the distribution of marine coastal litters around Zhoushan Island. A univariate analysis of variance was conducted to access the amount of litter in different landforms that include mudflats, artificial and rocky beaches. In addition, two questionnaires were designed for local fishermen and tourists to provide social scenarios. The results showed that the distribution of litter in different landforms was significantly different, while the distribution of litter in different sampling points had no significant difference. The StRS survey showed to be a valuable method for giving a relative overview of beach litter around Zhoushan Island with less effort in a future survey. The questionnaire feedbacks helped to understand the source of marine litter and showed the impact on the local environment and economy.

  • The Curious Double-Life of Putuoshan As Monastic Centre and Commercial Emporium, 1684–1728 113 ©2021 by RCHSS, Academia Sinica
    Journal of Social Sciences and Philosophy Volume 33, Number 1, pp. 113–140 The Curious Double-Life of Putuoshan as Monastic Centre and Commercial Emporium, 1684–1728 113 ©2021 by RCHSS, Academia Sinica. All rights reserved. The Curious Double-Life of Putuoshan as Monastic Centre and Commercial Emporium, 1684–1728✽ Ryan Holroyd✽✽ Postdoctoral Research Associate Center for Asia-Pacific Area Studies, Research Center for Humanities and Social Sciences, Academia Sinica ABSTRACT This article investigates how the island of Putuoshan simultaneously acted as a Buddhist monastic centre and a maritime shipping hub from the Qing dynasty’s legalisation of overseas trade in 1684 until the 1720s. It argues that because overseas trade during the Kangxi era was inconsistently regulated, a mutually beneficial relationship developed between Putuoshan’s Buddhist mon- asteries, the merchants who sailed between China and Japan, and the regional naval commanders on Zhoushan. Instead of forcing merchant vessels to enter ports with customs offices, the naval commanders allowed merchants to use Putuoshan’s harbour, which lay beyond the empire’s trade administration system. The monasteries enjoyed the patronage of the merchants, and so rewarded the naval commanders by publicly honouring them. However, a reorganisation of the empire’s customs system in the mid–1720s shifted the power over trade to Zhejiang’s governor general, who brought an end to Putuoshan’s special status outside the administration around 1728. Key Words: maritime trade, Qing dynasty, Putuoshan, Buddhist history ✽I would like to express my gratitude to Liu Shiuh-Feng, Wu Hsin-fang, Su Shu-Wei, and the two anonymous reviewers of my paper for taking the time to read it and for offering patient and helpful advice.

Introduction II. Theoretical Background on Port Competition and Co-operation III. A Comparative Analysis of Ports in the Yangtze River IV. Analysis of relationship between Shanghai port and Ningbo-Zhoushan port V. Summary and Suggestion Abstract With the course of the integration of global economy accelerating, and the speedy growth of world trade, important nodes of global logistics and ports acquire more and more important status in the global economy. Ports with the development of Chinese economy and especially with the rapid growth of the foreign trade have made a great progress. This research mainly focuses on the study of the competition and cooperation between neighboring ports. Several models were developed in the research to analyze the relationship between Shanghai port and Ningbo-Zhoushan port. The research results show that the two ports enter into competition with each other. Ports are faced with competition not only from domestic ports but also from their counterparts in other countries. Therefore, Shanghai port and Ningbo-Zhoushan port should avoid competition and join hands in developing the resource reasonably in Zhoushan and achieving a regional scale economy, so that the entire ports in the region of the Yangtze River Delta can have a better competitive power.

  • The Evolution Pathways, Dynamics and Perspectives of Ningbo-Zhoushan Port (China)
    From a feeder port to a hub port: the evolution pathways, dynamics and perspectives of Ningbo-Zhoushan port (China) Abstract: This paper analyses the spatio-temporal evolution of Ningbo-Zhoushan port growing from a feeder port to a hub port finding the historical pathways followed by its expanding in terms of container throughput capacity and total traffic. The dynamic mechanism of evolution is the results of economic globalization, containerization and its natural endowments in channel and terminal depths. Analysis of the traffic evolution and its underlying dynamics suggest 3 periods in the development processes of container transport in Ningbo-Zhoushan: (1) adoption period (1986-2000) in which the main dynamics is the impact of the Chinese ‘Open Door policy’; (2) acceleration period (2001-2008) in which the dynamics is related of the mainland China’s entry into the WTO; (3) peak growth period (2009-now) in which the dynamics is impacted by the anti-crisis strategy against the financial and economic crisis in 2008. We analyse the perspectives of Ningbo-Zhoushan port. ARIMA model is employed to forecast the container traffic in the coming future; about after 2026, the throughput in Ningbo-Zhoushan port would reach about 49 million TEU which would be approximately equal to that of Shanghai port. The resultant port development would exemplify a model of spatial distribution such as a multi-layered gateway hub. In the respect of growth potential, Ningbo-Zhoushan port possesses excellent coastline resource suitable for deep-water berthing, bonded port policy and free trade zone policy. Geographical position, service level, hinterland economic level and government will support its perspectives.
