Historical geographic information system construction echoes the call of academic development in the information era and demonstrates the in-depth advancement of history studies. In recent years, an increasing number of data platforms have been built to facilitate historical information storage, display, management and analysis. In such a context, the geographic information system(GIS) begins to contribute to the study of Chinese history. Its contribution is highlighted in nine areas: historical climate, fluvial landforms, town economies, rural settlements, hydraulic societies, environmental changes, ancient cities, ancient maps and HGIS-enabled research methods. The application of GIS to the study of Chinese history initiates a reform in research methods and at the same time upgrades the philosophy of history studies, facilitating the utilization of a diversity of historical data(documents, ancient maps, remote-sensing images, archaeological information, etc.) for dynamic tracing and multi-factor comprehensive research. At present, restricted by traditional disciplinary boundaries, the construction of HGIS platforms remains slow and insufficient, making it difficult to extensively apply GIS to the study of Chinese history. 展开更多

Living Cephalotaxus (plum yews) occurs mainly in East Asia and North of Indo-China peninsula. The study of original taxonomic literatures found that, in early days, the plum yews had ever been described as palnts of Taxus (Taxaceae). Since after the genus name Cephalotaxus Sieb. & Zucc. was firstly cited (from inedited and unpublished Flora Japonica) by Endlicher in 1842, most taxonomist thought which is the earliest time of the genus Cephalotaxus Sieb. & Zucc. was set. However, the genus Cephalotaxus Sieb. & Zucc. was formally effective and valid published by Sieb. & Zucc. in Flora Japonica in 1870 so that there exists some confusions in chronological order. Originally as a genus, Cephalotaxus was included in family Taxaceae and Neger (1907) separated Cephalotaxus from Taxaceae and set family Cephalotaxaceae. Later, Fu (1984) divided Cephalotaxus up into two sections of Cephalotaxus Sieb. & Zucc. sect. Pectinatae L. K. Fu and Cephalotaxus Sieb. & Zucc. sect. Cephalotaxus L. K. Fu on the bases of C. oliveri Masters differ significantly from other taxa of Cephalotaxus in morphological characteristics. Although the plum yews was a little genus of conifers, up to now, about 77 taxa have still been published by taxonomist in different countries or regions. Among them, C. tardiva Sieb. ex Endl. (1847), C. umbraculifera Sieb. ex Endl. (1847), C. sumatrana Miq. (1856) and C. celebica Warb. (1900) have been combined to Taxus, and C. argotaenia (Hance) Pilger (1903) has been combined to Amentotaxus. And at the same time, those taxa existing in Cephalotaxus courently which were accepted by most taxonomist in different countries was also cited in acticle. Lastly, the paper thought presently there still exists many debates about binary classification of Cephalotaxus and the nomenclature of this genus still particularly confusing. Based on some controversial problems, we also point out some taxonomically researching directions at creating some order out of the chaos. 展开更多

In Chinese language studies, both “The Textual Research on Historical Documents” and “The Comparative Study of Historical Data” are traditional in methodology and they both deserve being treasured, passed on, and further developed. It will certainly do harm to the development of academic research if any of the two methods is given unreasonable priority. The author claims that the best or one of the best methodologies of the historical study of Chinese language is the combination of the two, hence a new interpretation of “The Double-proof Method”. Meanwhile, this essay is also an attempt to put forward “The Law of Quan-ma and Gui-mei” in Chinese language studies, in which the author believes that it is not advisable to either treat Gui-mei as Quan-ma or vice versa in linguistic research. It is crucial for us to respect always the language facts first, which is considered the very soul of linguistics. 展开更多

This paper reviews the history and progress of research on active tectonics in China and overseas.By giving a brief introduction on the history of active tectonic research in China and other countries,the paper sums up the process and development of quantitative investigation of active tectonics since the 1980s.The focus is on the main efforts and progress made in China on certain aspects of research,such as basic surveys and applied investigation of active tectonics,the study of theories related to regional active tectonics and their kinematics and geodynamics,surveys on coupling relations between deep and shallow structures,active fault surveys and prospecting and seismic hazard assessment in urban areas,as well as the efforts made using Quaternary geochronology.Furthermore,the paper looks back on Chinese quantitative investigation of active tectonics in China and sums up cognitions derived from studies on the determination of several basic and measurable parameters of active tectonics.These parameters include the length of fault and fault segmentation,coseismic slip and cumulative slip,fault slip rate,the sequence of paleoearthquake events and the time elapsed since the most recent event.At the same time,efforts and progress made in China on assessing the long-term seismic potential for active faults and evaluating the risk from potential active fault movement have been reviewed by summarizing research on developing theories,models,methods and the application of time-dependent seismic potential to probabilistic assessment,magnitude estimation for potential earthquakes on active faults,and the forecast of potential risk caused by active fault movement.Finally,in consideration of the realities and problems in the research of active tectonics in China,the authors put forward several suggestions for issues worthy of more attention for further investigation in the future. 展开更多

The first modem survey of the Dead Sea was performed by the Geological Survey of Israel in 1959-1960, and the report published remains the baseline study for our understanding of the physical and chemical properties of the lake. At the time the Dead Sea was a meromictic lake with a strong salinity gradient separating the deep waters (〉40 m depth) from the less saline surface waters. A few results of analyses of deeper water samples collected in the 1930s were reported, but overall we have very little information about the structure of the lake's water column before the 1959-1960 survey. However, it is little known that data on the physical and the chemical structure of the Dead Sea water column were obtained already in the middle of the 19~ century, and the information collected then is highly relevant for the reconstruction of the limnological properties of the lake in earlier times. The expedition of Lieutenant William Lynch (U.S. Navy) in 1848 reported the presence of a temperature minimum at a depth of-18 m, and also retrieved a water sample collected close to the bottom for chemical analysis. In 1864, the French Dead Sea exploration by the Duc de Luynes and his crew yielded detailed density and salinity profiles for a number of sampling stations. The results of these pioneering studies are discussed here, as well as the sampling equipment and measuring instruments used by the 1848 and the 1864 expeditions. 展开更多

The Olympic Games, as the global sports event, attract many countries in the world to participate in and they always take obtaining the right of holding it as the pride of the country. With the constant development of the Olympic Games, people have proposed higher requirements for it and the reformation is eagerly needed and the reformation is mainly concentrated on the item setting. According to a large amount of theoretical research to the item setting of Olympic Games in academia, there is big issue about the item setting for the current Summer Olympic Games which has sustained for a long time. Its practical representations are the contradiction between narrowing the scope of the Olympic Games and borrowing in the new items and the contradiction of gender equality in item setting and also the contradiction of balancing the business value and social value. Therefore, this thesis will mainly study on the evolution and value of the item setting of the Summer Olympic Games and propose reasonable improvement measures for the issue of the item setting, combining with the practical conditions, and thus to better promote the sustain development of the Summer Olympic Games. 展开更多

Discussions on grasping the laws and trends of historical development take a fundamental theoretical position in the scientific system of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era.Xi Jinping’s important statements have systematically answered such questions as what type of laws and trends of historical development should be followed,how did the Party follow the laws and trends of historical development in its centennial history,and how should the laws and trends of historical development be followed in a new era.The birth of the Communist Party of China(CPC),the victory of China’s War of Resistance against Japanese Aggression,the founding of the People’s Republic of China,and the unveiling of a new era for reform and opening up and socialism with Chinese characteristics are all the results of grasping the laws and trends of historical development.Over the past century,the Party has followed the laws and trends of historical development and continuously advanced the sinicization of Marxism on the basis of adhering to the unification between truth and values.In pursuit of“putting people first,”the Party has courageously been reforming itself and made relentless progress in the great endeavor of Party building.History shows that a keen appreciation of the laws and trends of historical development is an important sign of political maturity for a proletarian party.Only by applying Marxism according to current times and conditions will we keep abreast with the laws and trends of historical development.We should establish a broader concept of history and identify the laws and trends of historical development from the interactions and linkages between China and the rest of the world.We must recognize and promote the outstanding role of great leaders in steering the country in line with the laws and trends of historical development. 展开更多

In the evolution of modern railway thought,it includes not only the discussion of railway planning,sovereignty,debt,and construction,but also the discussion of spiritual guiding ideology such as“Tao,body and utility”and“material and spirit”.From the perspective of the relationship between road and equipment,the development of modern railway thought in China has experienced three stages.During the Westernization Movement,Li Hongzhang and other people expounded the benefits brought by railway construction from the angle of“utility”,and believed that there was still a unity of“Tao and style”.After the Sino-Japanese Naval Battle,with the emergence of the theory of railway sovereignty and the theory of dividing China,Kang Youwei and others questioned the thought of Westernization school.The unified Tao body was divided into two parts:China and the West.After the May Fourth Movement,railway,as a product of western material civilization,was compared with Eastern spiritual civilization by Liang Shuming,Li Dazhao,and others.The conflict between material and spirit made the Western“Tao style”evolve into the Europe-American way of pursuing“scientific spirit”and the Soviet-Russian way of exploring the ideas of revolution and transformation.The railway has thus become an important carrier of the“scientific spirit”and socialism. 展开更多

Jujube(Ziziphus jujuba Mill.),or Chinese date,is the most important species of Rhamnaceae,a large cosmopolitan family,and is one of the oldest cultivated fruit trees in the world.It originates from the middle and lower reaches of the Yellow River,the‘mother river’of the Chinese people.It is distributed in at least 48 countries on all continents except Antarctica and is becoming increasingly important,especially in arid and semiarid marginal lands.Based on a systematic analysis of the unique characteristics of jujube,we suggest that it deserves to be recognized as a superfruit.We summarized historical research achievements from the past 3000 years and reviewed recent research advances since 1949 in seven fields,including genome sequencing and application,germplasm resources and systematic taxonomy,breeding and genetics,cultivation theory and techniques,pest control,postharvest physiology and techniques,and nutrition and processing.Based on the challenges facing the jujube industry,we discuss eight research aspects to be focused on in the future. 展开更多

Sinkers are quicksand enthusiasts that crave the sensation of being trapped in deep mud while being sucked downward. Although humans have been interested in quicksand over the years (particularly through film), there remains a void of research into the meaning and value in the lives of those who engage in a recreational pursuit of quicksand, most notably the community of individuals who self-describe as sinkers. The purpose of this exploratory study was to examine if sinking can contribute to a participant’s understanding of history and natural resources at state parks. In order to obtain a better understanding of the effects, a qualitative study was conducted in the summer of 2016 at Stephen C. Foster State Park, a state park adjacent to Okefenokee Swamp. The researchers exercised grounded theory techniques and inductive content analysis to analyze interview data and compile coded text into four main categories: learning, enjoyment, traveling, and economic impact. Findings suggest that participants believed their knowledge of park history and natural resources increased through a recreational pursuit of quicksand. 展开更多
