Evolution and Governance of the Structure of Marine Economic Networks in China’s Coastal Areas: Based on Sea-related A-share Listed Companies

Data on discrete,isolated attributes of the marine economy are often used in traditional marine economic research.However,as the focus of urban research shifts from internal static attributes to external dynamic linkages,the importance of marine economic net-work research is beginning to emerge.The construction of the marine economic network in China’s coastal areas is necessary to change the flow of land and sea resources and optimize regional marine economic development.Employing data from headquarters and branches of sea-related A-share listed enterprises to construct the marine economic network in China,we use social network analysis(SNA)to discuss the characteristics of its evolution as of 2010,2015,and 2020 and its governance.The following results were obtained.1)In terms of topological characteristics,the scale of the marine economic network in China’s coastal areas has accelerated and expan-ded,and the connections have become increasingly close;thus,this development has complex network characteristics.2)In terms of spatial structure,the intensity of the connection fluctuates and does not form stable development support;the group structure gradually becomes clear,but the overall pattern is fragmented;there are spatial differences in marine economic agglomeration radiation;the radi-ation effect of the eastern marine economic circle is obvious;and the polarization effect of northern and southern marine economic circles is significant.On this basis,we construct a framework for the governance of a marine economic network with the market,the government,and industry as the three governing bodies.By clarifying the driving factors and building objectives of marine economic network construction,this study aims to foster the high-quality development of China’s marine economy.

RELATIVE SEA LEVEL RISE AND ITS EFFECTS ON ENVIRONMENT AND RESOURCES IN CHINAS COASTAL AREAS

Due to global climate warming and natural and man-made land subsidence etc., relative sea level rise in the coastal plains of China will exceed 2-3 times over the golbal mean value during the first half part of the 21st century. It will result in a series of adverse impacts on evolution of natural environment and socioeconomic development of the coastal area. This paper analyses environmental and resource effects induced by relative sea level rise in China's coastal areas on the basis of rough estimate of future relative sea level rise. These effects include inundating tidal flat and wetlands and increase in inundated risk of coastal habitable land,exacerbating storm surge. coastal erosion, flooding and salt water intrusion hazards.as well as endangering land. water. tourism and living resources and their utilization.

Validation and application of multi-source altimeter wave data in China＇s offshore areas

Studies of offshore wave climate based on satellite altimeter significant wave height（SWH） have widespread application value. This study used a calibrated multi-altimeter SWH dataset to investigate the wave climate characteristics in the offshore areas of China. First, the SWH measurements from 28 buoys located in China＇s coastal seas were compared with an Ifremer calibrated altimeter SWH dataset. Although the altimeter dataset tended to slightly overestimate SWH, it was in good agreement with the in situ data in general. The correlation coefficient was 0.97 and the root-mean-square（RMS） of differences was 0.30 m. The validation results showed a slight difference in different areas. The correlation coefficient was the maximum（0.97） and the RMS difference was the minimum（0.28 m） in the area from the East China Sea to the north of the South China Sea.The correlation coefficient of approximately 0.95 was relatively low in the seas off the Changjiang（Yangtze River） Estuary. The RMS difference was the maximum（0.32 m） in the seas off the Changjiang Estuary and was0.30 m in the Bohai Sea and the Yellow Sea. Based on the above evidence, it is confirmed that the multialtimeter wave data are reliable in China＇s offshore areas. Then, the characteristics of the wave field, including the frequency of huge waves and the multi-year return SWH in China＇s offshore seas were analyzed using the23-year altimeter wave dataset. The 23-year mean SWH generally ranged from 0.6-2.2 m. The greatest SWH appeared in the southeast of the China East Sea, the Taiwan Strait and the northeast of the South China Sea.Obvious seasonal variation of SWH was found in most areas; SWH was greater in winter and autumn than in summer and spring. Extreme waves greater than 4 m in height mainly occurred in the following areas： the southeast of the East China Sea, the south of the Ryukyu Islands, the east of Taiwan-Luzon Island, and the Dongsha Islands extending to the Zhongsha Islands, and the frequency of extreme waves was 3%-6%. Extreme waves occurred most frequently in autumn and rarely in spring. The 100-year return wave height was greatest from the northwest Pacific seas extending to southeast of the Ryukyu Islands（9-12 m）, and the northeast of the South China Sea and the East China Sea had the second largest wave heights（7-11 m）. For inshore areas, the100-year return wave height was the greatest in the waters off the east coast of Guangdong Province and the south coast of Zhejiang Province（7-8 m）, whereas it was at a minimum in the area from the Changjiang Estuary to the Bohai Sea（4-6 m）. An investigation of sampling effects indicates that when using the 1°×1°grid dataset, although the combination of nine altimeters obviously enhanced the time and space coverage of sampling, the accuracy of statistical results, particularly extreme values obtained from the dataset, still suffered from undersampling problems because the time sampling percent in each 1°×1°grid cell was always less than33%.

China's Manganese Geological Research and Prospecting have Achieved Great Breakthrough

Data announced by the Chinese Ministry of Land and Resources in 2015 suggest that China has discovered more than 480 manganese ore-producing areas, with manganese ore resource reserves up to 1.22 billion tons, including 0.303 billion tons of basic reserves and 0.915 billion tons amount of resource. Among these reserves, manganese carbonate ores account for 56%, manganese oxide ores （including spongy manganese ores） accounts for 25%, and other types of manganese ore occupy 19%. Rich ores with 〉30% manganese content only account for 5% of the total resource amount, and the remaining 95% are poor manganese ores. Since 1983 when China first began to import, the imported manganese ores have increased annually by 25%. In 2001, the annual imported manganese ores reached 1.71 million tons. From 2010, the annual imported manganese ores increased by greater than 45%, reaching up to 12 million tons in 2015. Thus it seemed that the shortage of manganese ore resources will be a longterm phenomenon for China＇s economic development.

What Efforts has the Chinese Government Made to Reduce Educa­tional Inequality in Poor Areas?

Since the founding of the People’s Republic of China in 1949,China’s per capita education level has risen from less than two years to 9.91 years.However,as the province with the lowest per capita education level in China,Tibet has only reached the level of 6.75 years per capita.This illustrates the worrying educational inequality that still exists between China’s poorer and more developed regions.This educational inequality can also be expressed by the Gini coefficient of education.In order to eliminate this educational inequality,the Chinese government has made great efforts.The Chinese government has expanded the demand for education through the right incentive system and the nine-year compulsory education law.On the other hand,the Chinese government directly or indirectly grants subsidies to education suppliers and demanders to achieve the purpose of increasing education output.Based on the positive externality of education itself,the Chinese government attaches great importance to the cultivation of human resources for offspring,and hopes to transform China’s quantity-based demographic dividend into quality-based demographic dividend,and finally realize sustained economic growth.We believe that some education-related policies promulgated by China have indeed reduced educational inequality in poor areas to some extent,but there is still potential for progress in further addressing educational inequality in poor areas by the Chinese government.

The Human Rights Legislation Practices of the Communist Party of China During the War of Liberation

During the War of Liberation,the liberated areas,under the leadership of the Communist Party of China,kept deepening and developing the concepts and ideas of protecting human rights,promulgated a series of human rights laws and related administrative programs,and put them into practice.The contents included not only the political rights of citizens but also their economic,social,and cultural rights,with emphasis on the protection of the rights to subsistence and development.The human rights legislation in the liberated areas has a wartime and class-based nature due to its social environment.It reflects the transition of the Communist Party of China from a revolutionary party to a ruling party on the historical stage.It played an important role in directing,advancing,and promoting the progress of democracy and the rule of law at that time and accumulated experience for the human rights legislation after the founding of the People’s Republic of China.History proves that the Communist Party of China has always been a political party dedicated to fighting for the human rights of the Chinese people,and only the Communist Party of China can lead China’s human rights development to a deeper level.

华北地区地壳上地幔S波三维速度结构

利用华北地区大型流动地震台阵的记录资料,采用近震和远震联合成像方法,得到了水平分辨率0.5°×0.5°、深至600km的S波速度结构.研究结果表明,上地壳S波速度结构与地表地质构造基本一致,燕山—太行山山脉均呈现高速异常,延庆—怀来盆地、大同盆地表现为低速异常,华北盆地内部的拗陷和隆起分别呈现低速和高速.唐山地区中地壳、山西裂陷盆地中下地壳存在明显的低速异常,可能分别与流体和热物质作用有关,有利于形成孕育强震的地质构造环境.90km的速度结构图像依然与地表的构造特征有较大的相关性,可能说明深部结构对地表构造有一定的控制作用.燕山隆起区岩石圈的厚度可达120～150km左右,华北盆地的岩石圈厚度可能在80km左右,太行山地区的岩石圈厚度介于两者之间.山西裂陷盆地上地幔低速层较厚,反映了该区不稳定的构造环境造成了地幔热物质的上涌.华北盆地下方220～320km出现的高速异常体,可能揭示了华北盆地上地幔仍然存在拆沉后残留的难熔、高密度的古老岩石圈地幔.研究区东部地幔转换带呈低速异常,推测可能与太平洋板块俯冲至该区下方地幔转换带前缘120°E左右的俯冲板块相变脱水有关.
