Reanalysis on the Spectral Characteristics and Materials of Jade Jue Unearthed from Lijiashan Ancient Tomb in Yunnan Province, China

Jade ware Jue is one of the most fashionable ornament in ancient China from the Neolithic Age to the Han Dynasty.In this study,the remnants of jade ware Jue,from Lijiashan ancient tomb group have been tested and analyzed respectively.The samples through a light etch surface showing glass luster and those with a severe etch surface showing earthen luster.With the aid of X-ray fluorescence Spectrometer(X-ray Fluorescence)test and X-ray diffraction(XRD)detection,the results show that tremolite is not the main mineral of the sample.The main components of the tested samples with light erosion are antigorite and talc,although the main components of the samples with severe erosion are calcite containing calcium carbonate barium.Furthermore,the research on jade ware Jue in Yunnan culture has not only contributed to our further understanding of the jade objects from Yunnan culture and the variety of jade material located in the Yunnan Province.It also provides a basis for the trace of the history and culture through the distribution and evolution of burial hierarchy laws.At the same time,the microscopic observation of the tested samples manifested a residual trace of“string”at the perforation,which has played a critical role in restoring the wearing of jade ware Jue from the tombs of the ancient Yunnan State and the handicraft skills at that time.

Development and Evolution of Papermaking in Ancient China based on the Uses and Forms of Paper

In the past,scholars have divided the history of Chinese papermaking into different stages based on the development of ancient papermaking technology,emphasizing the development and progress of papermaking in different historical periods but paying less attention to the changes in the form of paper.Here,the stages are defined based on changes in use and function rather than technological developments.When this approach is combined with the history of printing,books,calligraphy,and painting,the history of Chinese papermaking can be divided into the writing paper,writing and printing paper,printing paper,and calligraphy and painting paper periods.Different periods of paper have significant differences in texture,form,and performance owing to their different applications.This significant difference provides a reference for the identification of ancient papers and reveals the internal connection between the history of printing,books,calligraphy,painting,and papermaking.

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.

Sedimentary Environment Analysis of Ancient Sand Ridges from Zk23 Hole in the East China Sea

Abstract： Based on the analysis of core samples from the hole of Zk23 in the East China Sea Continental Shelf and by means of sedimentary stratigraphy, biostratigraphy and chronostratigraphy, the authors consider that the fine-sand deposition in borehole was part of buried ancient estuary sand ridges of the Yangtze River. The deposition history of study area around the hole before and after the glacial period as well as postglacial period is made clear after our research： （1） the estuarine sublayer -undersea delta facies strata was deposited under the fast sea level rise about 15 kaB.P; （2） sand ridges mostly consisting of fine-sand, were formed when the sea level was the fluctuant range of 60 - 80 m of isoba during the deglacial period around 15 - 12 kaB.P; （3） first silty clay and clay silt strata above the sand ridges were deposited during the period when the sea level rose fast from 12 to 7 kaB.P, and then it keeps stable to the present.

Eastern Ancient Terrane of the North China Craton

Based on the spatial distribution of ancient rocks and zircons, three ancient terranes older than ca. 2.6 Ga have recently been identified in the North China Craton, namely the Eastern, Southern, and Central Ancient Terranes. The Eastern Ancient Terrane is the best studied and understood of the three ancient terranes. It has a long geological history back to ca. 3.8 Ga ago and includes the areas of Anshan-Benxi, eastern Hebei, eastern Shandong and western Shandong. In Anshan-Benxi, several different types of 3.8 Ga rocks were discovered together with 3.1-3.7 Ga rocks, whereas 2.9-3.0 Ga K-rich granites and 2.5 Ga syenogranite occur on larger scales. In eastern Hebei, 3.0-3.4 Ga rocks and older detrital and xenocrystic zircons were identified. In eastern Shandong, there are a large volumes of 2.7 Ga and 2.9 Ga rocks. In western Shandong, early Neoarchean （2.6-2.7 Ga） intrusive and supracrustal rocks are widely distributed. Whole-rock Nd and zircon Hf isotope data suggest that both mantle additions and crustal recycling played important roles within the Eastern Ancient Terrane during almost every tectono-magmatic event. Most BIFs in the North China Craton are late Neoarchean in age and are distributed on continental crust along the western margin of the Eastern Ancient Terrane, probably suggesting that a stable environment was one of the key factors for the formation of large-scale BIFs.

Government's Responsibility for Control of Agricultural Environmental Pollution in China

In this paper,the current situation of agricultural environmental pollution caused by the increase of chemicals input in agriculture in China was analyzed,and it is found that agricultural pollution is related to agricultural industrial policies,urban-rural economic structure,funds input in pollution control,comprehensive environmental management,laws of pollution control,and so forth. To control agricultural pollution effectively,it is needed to implement integration of agricultural and environmental policies,establish environmentally friendly agricultural technology popularizing system,implement integrated planning and management of a basin,and set up and improve legislation to protect agricultural environment.

Gravity and magnetic field characteristics and regional ore prospecting of the Yili ancient continent, West Tianshan, Xinjiang Uygur Autonomous Region, China

Gold,iron,copper,lead-zinc and other mineral exploration in West Tianshan,Xinjiang Uygur Autonomous Region,has made remarkable progress in recent years.However,due to the dispute on the tectonic division of West Tianshan,the ore-controlling factors and the regional metallogenic laws are controversial.The authors analyze regional gravity data and notice that the high-value region corresponds to the Yili ancient continent,thus the southeastern boundary of the Yili ancient continent is delineated.Comparative analysis of gravity,aeromagnetic and geologic data reveals that the Tulasu basin,where some medium to large epithermal gold deposits locate,lies above the Yili ancient continent;the Yili Carboniferous-Permian rift extends in E-W direction,numbers of copper deposits have been found in the mid-west section of the rift which lies above the Yili ancient continent,whereas few copper deposits have been discovered in the east section which is outside the Yili ancient continent.Accordingly,the Yili ancient continent may be rich in gold,copper and other metal elements;the metal-bearing hydrothermal solution moves up with the activity of magmatism,and deposits in the favorable places(the Tulasu basin and the Yili Carboniferous-Permian rift),forming numerous small and medium gold,copper deposits,as well as some large and super-large gold deposits.Therefore,the tectonic-magmatic hydrothermal zone above the Yili ancient continent should be the prospective area for epithermal gold and copper polymetallic deposits.

THE NOMENCLATURE OF THE SOUTH CHINA SEA ISLANDS IN ANCIENT CHINA

The thesis studies the ancient place names recorded in Chinese ancient maps, such as Shanhuzhou, Changsha, Shitang, Qianlichangsha, Jiuruleizhou,Shixingshitang, Wanlishitang, Wanlichangti, Changshahai, Shitanghai, Nanoqi,Hongmaoqian, Dongsha, Hongmaqian, and more than 100 folk place manes recorded in Geng Lu Bu and some finding rePOrts. After that, it POints out that the formaer representing the colony of coral reef are general place names and the latter representing the individual coral reefs are particular place names. Both of them set up the place name system of the South China Sea islands in ancient China. It also POints out that it is the Chinese People who first name the South China Sea islands before west colonialists invaded the islands, and nine place names of itu Aha, Namyit island, Sincowe islands, Subi Reef, Lankian Cay, London Reef, Passukeak, Thitu island, and Duncan Island, which were used by the west coloniali are transliteration place names of Chinese folk place names, Lastly, the paper draw the conclussion that the namenclature of the South China Sea Islands in ancient China provide the strongist evidence that the South China Sea islands are parts of China.

Sedimentary Features of Shallow Ancient River Channels on the Northern Shelf of the South China Sea

Quaternary buried ancient river channels are widespread in the shallow-level sediments of the northern shelf of the South China Sea. The sedimentary sequence mainly of fluvial deposits comprise an important component part of the low-stand system tract and transgressive system tract in the study region. The plannar variation and spatial association of the sedimentary features such as incised valley fillings, deltaic foreset wedges and block slides of shelf-marginal fans reflect the palaeogeographic environment during the fall of the regional sea level in the northern part of the South China Sea. Based on the high-resolution seismic reflection data and gelogical data from boreholes, the present paper makes an integrated interpretation of the Quaternary ancient river channels in the shallow sediments of the study area, studies the sedimentary features of the ancient channels such as their spatial distribution, seismic facies reflection indicators, sedimentary facies and sand -body types, and discusses their formational setting and evolutionary model, with the main purpose to render a service to the hydrocarbon resources exploration and development and marine engineering in the northern shelf of the South China Sea.

On the Government Function Orientation in China's Agricultural Management Reform

Since the reform and opening up,China's market-oriented agricultural management reform has achieved remarkable results,but the reform has not yet been put in place,and there are some flaws in some areas of reform.To deepen the reform of government's agricultural management reform under the new situation,it is necessary to further define the boundary between government and market on the basis of following the general rules of world's agricultural development and considering China's special situation of agriculture,nail down the scope of government functions,pinpoint the key areas of reform,and actively promote the rapid development of China's characteristic modern agriculture.

The Pattern of Government Health Expenditure in China

For a while since the inception of economic system reform programs in 1980s,China's government investment in health was weakened.This resulted in healthcare provider's increasing reliance on user charges for their income,poorer access to healthcare for the vulnerable population groups,and increasing socioeconomic disparities in health and healthcare.To address these problems,China initiated a series of health sector reforms since late 1990s.Our comprehensive review study has found that indeed Chinese government spending on health has been increasing in recent years,especially since 2009,when the new Healthcare Reform Plan was announced.Still,China needs to both further strengthen government investment in health and address the structural imbalances in government health financing,in order to make the overall Chinese health system more equitable and more efficient.

On the Government's Responsibility in China's Rural Land Transfer

There is an urgent need for China's rural land transfer in order to develop modern agriculture,ensure food security,transfer rural population,and accelerate industrialization and urbanization.At present,there is still disordered transfer of rural land in China,making the interests of the transferors and transferees difficult to be effectively guaranteed;there is inefficient transfer,leading to decline in actual agricultural production level after transfer;there is jobless transfer,leading to difficult placement for rural surplus labor after transfer,seriously restricting rural land transfer.Therefore,the Chinese government's legal responsibility,economic responsibility and social responsibility in rural land transfer should be further strengthened.

Study on the ancient cultivated rice in China

The Positive Influence of Buddhism Upon the Development of Science and Technology in Ancient China

It is important and worthwhile to discuss what kind of influence Buddhism cast on the development of science and technology in ancient China. The author does not agree with Joseph Needham’s view:“There can be little doubt that on the whole its action was powerfully inhibitory”, and the author thinks Buddhism took a positive promotion and influence on the development of science and technology in ancient China as a whole. There were four main ways of Chinese Buddhism influence on ancient science and technology:(1) The Buddhist scriptures actually contain a wealth of knowledge of science and technology;the eminent Buddhist monks introduced them into China through translation, therefore enriched contents of science and technology in ancient China.(2) Some knowledge of science and technology in ancient Indian and other districts got into China along with the spread of Buddhism.(3) Ancient Chinese Buddhists took part in science and technology practice actively at that time, and they had got a series of achievements in science and technology.(4) Being inspired and affected by Buddhist scientific knowledge, those non-Buddhist scientists had engaged in many created work in a further step, and made much contributions to development of science and technology. The doctrine of Buddhism was not a complete hindrance to the development of science and technology, and the result turned out contrary in many respects that it had promoted development of science and technology. In fact, Chinese Buddhism had made many important contributions in the fields of astronomy, mathematics, medicine, and so on.

An Examination of Social Relief in Ancient China

Social assistance and relief to the impoverished and vulnerable groups is a timehonored tradition that has been continued throughout Chinese history.Although social and economic development varied from one historical period to another,poverty,being a social phenomenon,can be found in any historical society.Under no circumstances could the ruling class ignore the very existence of such special groups.To meet the needs of social development and political ruling,the imperial governments of all dynasties in Chinese history invariably offered social assistance and relief to the vulnerable groups to highlight their consideration and care of them at the state level.

Prospects of the New German Government’s China Policy

In contrast to the Merkel era, the emphasis on ideological disputes and competition with China is evident in the new German government's Coalition Treaty and several of its new ministers' expressions about China. Against the background of the rising antagonism between China and the West as well as the continuous efforts of the US to urge Europe to curb China in recent years, Germany's understanding of China tends to be negative. Besides, because of the changes in Germany's political landscape and in Sino-German economic and trade relations, the new government is likely to reinforce its defense against and pressure upon China, reduce its strategic dependence on China, strengthen the coordination with its European and American allies for a collective China policy, and compete for dominance in economy and trade, science and technology, global infrastructure, and rules and standards. Sino-German relations may fluctuate, but because of the binding of the economy and trade between the two countries, internal contradictions inside the Western Bloc, and the German tradition of diplomatic pragmatism, the new government will adjust its China policy on the basis of continuation, so that the reversal of the Sino-German relations is hardly to be triggered.

The transformation of China＇s economic and government functions

The content of China＇s economic transformation is not single, and this article argues that it includes three parts. The first is the reform of economic system, the second is the change in the pattern of economic growth, and the third is the adjustment of economic structure. Government is the leading force of China＇s economic transformation, and repeated reform of government institutions has brought about some changes to government functions. But problems are obvious that lag changes of government functions have become an obstacle in China＇s economic transformation. This article describes the historical evolution and the reality of China＇s economic transformation, and analyzes the main reasons of lag changes in government functions, and reveals that the transformation of government functions is the key for successful transformation of China＇s economy.
