The development of tidal barrage in Zhejiang Province presented the ebb and flow trends. Ocean energy This paper introduced the resource status of tidal energy in Zhejiang Province. The five development stages of Tidal barrage tidal barrage technology and the profiles of tidal power plant (TPP) in operation were reviewed, and problems Tidal range and experiences were discussed. Some available future works for the development of tidal barrage were also Tidal power plant (TPP) proposed. The direction of utilizing tidal potential energy in the future is to update the generating units, improve construction skills and run optimization of operation in order to reduce costs and mitigate the impact on the environment. Actively exploring construction methods of medium to large-scale of TPPs are helpful to accelerate the utilization of tidal energy resources in Zhejiang Province and coastal areas in China. 1. Introduction earlier than other types of renewable energy [13]. The wide-range utilization of tidal energy in China began in the mild 50s of the 20th Tidal energy is a form of renewable energy generated by the century [14,15]. According to the relevant literature, over 100 TPPs periodic change in the ocean envelop of earth which results from the were built in China with a total capacity of 7638 kW [6]. Currently, gravitational interaction of Moon, Sun and Earth [1,2]. Tidal energy there are only two TPPs in operation, one is the Jiangxia Experimental includes potential energy and kinetic energy. Modern technology of TPP and another is the Haishan TPP [16]. These two stations were both harvesting the tidal energy center around two main methodologies, i.e. located in Yueqing Bay in Zhejiang Province, China. tidal barrage and tidal stream. Tidal barrages convert the potential China's major development and construction in utilization of tidal energy of the tides to electricity while tidal stream turbines use the energy resources are concentrated in the area of Zhejiang Province. kinetic energy of the tides. Tidal barrage technology utilizes a head Therefore, the review of the development of TPPs in Zhejiang Province difference between two bodies of water [3,4]. A typical tidal barrage is a is critical to understand the utilization history of tidal energy in China. wall, built across a bay or estuary to separate the water into two areas In this paper, the main subject is to give a comprehensive review of the when the tide flows in or out. The wall barricades the flow of the tide development of tidal barrage technology in Zhejiang Province, China. and creates a head difference. Turbines in the barrage generate In the next part of this paper, Section 2, a brief overview on the electricity by using the head difference. resource status of tidal energy in Zhejiang Province is presented. Then, Only a few large TPPs have been built around the world [5,6]. Such the five development stages of tidal barrage technology are summarized as the 240 MW tidal range facility at La Rance, France completed in in Section 3. Section 4 describes the profiles of TPP in operation, 1966 [7], the 1.7 MW tidal range station at Kislaya Guba, Russia including the Jiangxia Experimental TPP and Haishan TPP. completed in 1968 [8], the 4.1 MW Jiangxia Experimental TPP in Meanwhile, problems and experiences from the operating TPPs are Zhejiang Province, China in operation from 1980, the 20 MW also discussed.

Province As shown in Fig. 2, the larger estuary and bay from north to south are Qiantang River Estuary, Hangzhou Bay, Yong River Estuary, The utilization of tidal energy in Zhejiang Province, similar to that Xiangshan Harbor, Sanmen Bay, Taizhou Bay, Jiao River Estuary, developed in China, mainly underwent five stages as follows. Yueqing Bay, Wenzhou Bay, Ou River Estuary, Feiyun River Estuary, and Ao River Estuary. 3.1. Tidal energy resources survey stage (1950s – 1960s) The tidal range increased from east to west in the bay and decreased from south to north in nearshore region. The annual mean tidal range In July 1958, due to the demand of rapid development in China of the southern bay was above 5 m, which of Zhoushan Islands was industrial and agricultural production, an upsurge of utilization of tidal – merely 3 3.5 m. After the tidal wave entering the bay, the tidal range energy was set off in the provinces near the coastal areas. Zhejiang often increases due to narrowing sections. For example, the tidal range Province emphasized on the Qiantang River for the development of of apex of Hangzhou Bay was twice more than the one at the mouth, tidal energy, carrying out a series of resources investigation. After the and the tidal range of apex of Yueqing Bay was 1 m higher than the one first national survey of tidal energy resources, including eleven larger at the mouth. The largest tidal range ever measured in Hangzhou bay estuaries and bays in Zhejiang Province, it estimated that the available was 9 m while over 8 m was measured in Yueqing Bay as well. installed capacity of tidal power is 9.16×106 kW, and the annual energy As the tidal range and tide storage area of the estuary and bay are output is 2.27×1010 kW h as stated in the Survey Report of Tidal considerable, there was a great potential for utilizing rich tidal energy energy Resources in Zhejiang Coastal Area [19]. in Zhejiang Province. According to statistics in research projects [18], In October 1958, National Tidal Energy Conference was held in China's available installed capacity of tidal power is 2.16×107 kW and 10 Shanghai, discussing mainly on the construction of the Qiantang River the annual energy output is 6.19×10 kW h, of which the Zhejiang Estuary TPP.

  • The Chinese in Spain
    The Chinese in Spain Gladys Nieto* ABSTRACT During the past 15 years, the Chinese migrant community in Spain has grown significantly. Originally a small and dispersed population, it now ranks fourth among the migrant groups from non-European Union (EU) countries. Its increasing presence in daily urban life is evident everywhere. Even though the Chinese community has a long history of settlement in Spain, the Spanish population still considers the Chinese as a closed and somewhat mysterious community. References to exaggerated stereotypes and prejudices regarding their activities and social organization can often be overheard in daily conversations. However, China, usually considered exotic and remote, has recently assumed greater importance in Spain’s foreign policy. Thus, the Spanish Government has drawn up the Asia-Pacific Framework Plan for 2000- 2002 as part of its international policy considerations, thereby extending its interests to include areas well beyond its traditional foreign policy focus on Latin America. The Government’s objectives are to expand its economic relations with Asia, to enhance trade and tourism with the area, expand the development cooperation with China, the Philippines, and Viet Nam – countries defined as top priorities for the Spanish Government – and to reinforce linguistic and cultural ties with these countries (Bejarano, 2002). In support of the Asia-Pacific Framework Plan, the Casa Asia (House of Asia) was estab- lished in Barcelona in 2002, an institution created to organize academic and artistic activities in order to promote the knowledge of the region among Spaniards, and to foster political, economic, and cultural relations with Asia. The Government intends to pursue two important objectives related to the increasing commitments it is seeking to establish with China, and which are also of relevance to the overseas Chinese as the principal social actors in- volved.

  • 1 Testimony Before the U.S.-China Economic and Security Review
    Date of the hearing: January 26, 2012. Title of the hearing: China’s Global Quest for Resources and Implications for the United States Name of panelist: Brahma Chellaney Panelist’s title and organization: Professor of Strategic Studies, Center for Policy Research, New Delhi. Testimony before the U.S.-China Economic and Security Review Commission China has pursued an aggressive strategy to secure (and even lock up) supplies of strategic resources like water, energy and mineral ores. Gaining access to or control of resources has been a key driver of its foreign and domestic policies. China, with the world’s most resource-hungry economy, is pursuing the world’s most-assertive policies to gain control of important resources. Much of the international attention on China’s resource strategy has focused on its scramble to secure supplies of hydrocarbons and mineral ores. Such attention is justified by the fact that China is seeking to conserve its own mineral resources and rely on imports. For example, China, a major steel consumer, has substantial reserves of iron ore, yet it has banned exports of this commodity. It actually encourages its own steel producers to import iron ore. China, in fact, has emerged as the largest importer of iron ore, accounting for a third of all global imports. India, in contrast, remains a major exporter of iron ore to China, although the latter has iron-ore deposits more than two-and-half times that of India. But while buying up mineral resources in foreign lands, China now supplies, according to one estimate, about 95 per cent of the world’s consumption of rare earths — a precious group of minerals vital to high- technology industry, such as miniaturized electronics, computer disk drives, display screens, missile guidance, pollution-control catalysts, and advanced materials.

  • Status of Freshwater Fish Biodiversity in the Yangtze River Basin, China
    Status of freshwater fish biodiversity in the Yangtze River Basin, China Jianhua Li College of Environmental Science and Engineering, Tongji University, Shanghai 200092, China ABSTRACT Tere are over 1000 species in Chinese freshwater fish fauna, in which at least 717 species in 33 families inhabit rivers, along with a further 66 species spend part of their lives in rivers. The other species are mainly confined to esturine reaches, but they swim upsteam occasionally. According to the recently gathered information on freshwater fish biodiversity, 361 species are found in the Yangtze River Basin, of which 177 species are endemic to the Yangtze River. Pessimistically, 25 species in the Yangtze River Basin are listed as endangered species in the China Red Data Book for fishes. the Three Gorges Dam (TGD). Regarding to the species richness patterns along the basin altitude gradient of total, non-endemic and endemic fishes were different, which non-endemic richness showed a significant decrease with increasing elevation, whereas endemic richness had a couple of peaks including a major peak at around 500-m and a minor peak at near 1800-m. Meanwhile, species density also presented two peaks at mid elevation zones for endemic and non-endemic fishes, such as 1500-2000m and 3500-4000m for endemic fishes, and 500-1000m and 3500-4000m for non-endemic fishes, respectively. In addition, structure of endemic fish assemblages in the upper Yangtze River was highly correlated with local topographic and geomorphic characteristics. The combined effects of pollution, habitat degradation and overexploitation have reduced fish stocks dramatically. Hydrological alterations are perhaps the largest threat to fish biodiversity in the Yangtze River Basin, such as dam construction and disconnection between river and its lakes.

Based on a survey of enterprises producing low-voltage electric appliances, we find that the entry of a large number of new enterprises producing poor-quality products was followed by the upgrading of product quality and the introduction of new marketing strategies. Hence, we attempt to identify statistically the mechanisms underlying this evolutionary process of industrial development. JEL classification numbers: O12, P23 2 1. Introduction China’s substantial economic growth in the 1980s is attributable mainly to township- and village enterprises (TVEs) according to Chen et al. (1992), Jefferson et al. (1996), and Otsuka et al. (1998). However, the private sector emerged as the new engine of Chinese economic growth in the 1990s. The heartland of this private sector growth is Zhejiang Province, particularly in Wenzhou City as Zhang (1989), Nolan (1990), Dong (1990), Wang (1996), Li (1997), Zhang (1999) and Sonobe et al.
