ANALYSIS OF REMOTE SENSING ARCHAEOLOGY ON TRAFFIC FUNCTION TRANSFORMATION OF TONGJI GRAND CANAL IN SUI AND TANG DYNASTIES

In China, most directions of river flowing are from west to east. During historic period, since the water traffic played an important role, it was very important to form a cross-horizontal net of water carriage route. Canals should be dug so as to make up the lack of north-south river. Tongji Grand Canal, dug in the first year of Daye (605 A.D.) in the Sui Dynasty, was the important component of north-south system of Grand Canals in China. It promoted economic and social development of the Sui, Tang and Song dynasties (605 A.D.-1279 A.D.). As Tongji Canal (i.e. Tongji Grand Canal) flowed across the Huaibei Plain, which is aggraded by abundant mud and sand deposit resulted from the Huanghe (Yellow) River flooding, many traces (such as old channel) and human culture heritages were buried under mud-sand. Tongji Canal was silted up, and disappeared in the Jin Dynasty (1115 A.D.-1234 A.D.). From then on, there were many different stories about the flowing route of the canal in historical literature. Based on space-bone and air-bone remote sensing imagery, we attempt to search the old channel of Tongji Canal, and supplement historical record. The paper discusses transformation process of Tongji Canal’s traffic function, and resumptively summarizes the reasons of the transformation, which results from synthetic function of physical geographical, political, economic, and social conditions.

Ancient Canal Town——Tai’erzhuang

IN June 2014,the 2,500-year-old Beijing-Hangzhou Grand Canal,running a length of 1,797 kilometers,made the World Cultural Heritage list.The 42.5-kilometer-long stretch at Tai’erzhuang（now a district of Zaozhuang City,Shandong Province）,at the junction of the upper and middle sections,is widely known as the sole east-west waterway of the Grand Canal.

关于歌剧《运河谣》剧本的若干思考

关于创作歌剧《大运河》的想法已经有好几年。为此作了一些准备工作,阅读了大量有关中国运河文化与运河历史的著作,也沿着京杭大运河作过许多实地考察。渐渐形成了关于剧本主要内容的构想。首先,想做一部民族歌剧。我们现在舞台上出现的大量歌剧作品,基本都是西洋样式的歌剧。西洋歌剧的做法是，音乐受到极大的重视，但对剧本的文学性和戏剧性的要求不高。所以现在我们知道许多西洋著名歌剧的作曲者，但不太知道它们的编剧是谁。有相当部分的西洋歌剧剧本，

Mapping Mythical and Imaginary Places in d＇Anville＇s Carte de I＇Amrrique Meridionale

This article aims to discuss the blank spaces in the cartography of the Enlightenment, examining one map by French mapmaker Jean Baptist Bourguignon d＇Anville, the Carte de l＇Amdrique m＆idionale, first printed in 1748. Here, emptiness reflects the limits of the geographical knowledge of that continent. Moreover, it also indicates that a mythological geography still present on the maps of the time. This was also evident in the case of Lake Parima, which is represented within the Amazon region. In the first manuscript or print version of the Carte de [＇Amdrique mdridionale in 1748, on sheet l--depicting the Amazonian region--one can see that Lake Parima is not presente. Following the information of the French La Condamine had gathered on his expedition traveling down the Amazon and scorning tradition, d＇Anville did not include Lake Parima but Lake Amucu, placing it not in Guiana, in the Portuguese portion of the territory, below the Orinoco River and to the north of the Amazon. This was due to a manuscript map drawn up by a Prussian whom La Condamine had met during his trip down the Amazon, Nicholas Horstman. In the 1760 version--we see to our surprise that the geographer has included Lake Parima. This article aims to discuss the disappearance of the lake in the first version of the map and why does he then add it in 1760.

Comparative Analysis of the Spatial-temporal Distribution and Influencing Factors of the Tourism Industry in Three Cities along Beijing-Hangzhou Grand Canal in China

The temporal-spatial pattern of linear cultural heritage in the context of the tourism industry is closely linked to heritage management.Using the 1800 km long Beijing-Hangzhou Grand Canal as an example,this study compared the dynamic evolution of tourism businesses in Beijing,Liaocheng,and Yangzhou at three time points(2010,2015,and 2019)via nearest neighbor analysis,kernel density estimation,and the standard deviational ellipse.Next,a Geo-detector was used to examine the influencing factors.The results reveal significant growth regardless of the quantity or agglomeration degree from 2010 to 2019,and the direction of industrial expansion is consistent with the flow direction of the canal.Moreover,the explanatory powers of factors related to socioeconomic development and canal resources are obviously stronger than those of the natural environment.The findings of this study offer theoretical constructs and policy recommendations for the sustainable development of the Beijing-Hangzhou Grand Canal and other linear cultural heritage sites.

Developing Regional Ecological Networks along the Grand Canal based on an Integrated Analysis Framework

As a complex social ecosystem network,the area along the Grand Canal has a prominent contradiction between the demand for economic development and the protection of natural resources,which means that there is an urgent need for ecological restoration and environmental protection.Using ArcGIS,Conefor,Linkage Mapper and other software platforms,this paper developed an integrated analysis framework,through loose coupling of the attribute-function-structure index system and a series of methods such as the least cost path,circuit theory and moving window search.Based on the framework,we resolve a series of scientific issues in developing regional ecological networks,such as the selection of ecological sources,the simulation of potential ecological corridors,the assessment of the importance of ecological sources and corridors,and the identification of key ecological nodes.Moreover,an overall conservation pattern of the regional ecological network is constructed.The results show that:1)A total of 88 important ecological sources are identified in the study area.The patches with high centrality values are mainly concentrated in the southern mountainous area and the areas with abundant rivers and lakes.2)A total of 138 important ecological corridors are identified,and they are not evenly distributed.Extremely important corridors mostly appear between important patches,and very important corridors are mainly distributed in the central area.3)Fifteen ecological pinch points are extracted,and they are mainly concentrated in the northern part of the study area and eastern Zhejiang Province.The barriers are mostly concentrated in the southern and northern parts of the study area.4)Combining the demands of ecological protection and socioeconomic development,we propose an overall ecological conservation pattern of"one axis,five sections,multiple cores and multiple nodes"to effectively guide future ecological restoration work.These results can provide a useful reference and spatial guidance for decision makers in terms of ecological restoration and cooperation on cross-regional ecological protection along the Grand Canal.

The Changing Cold Regions Network:Observation,diagnosis and prediction of environmental change in the Saskatchewan and Mackenzie River Basins,Canada

Climate change is causing rapid and severe changes to many Earth systems and processes,with widespread cryospheric,ecological,and hydrological impacts globally,and especially in high northern latitudes.This is of major societal concern and there is an urgent need for improved understanding and predictive tools for environmental management.The Changing Cold Regions Network(CCRN)is a Canadian research consortium with a focus to integrate existing and new experimental data with modelling and remote sensing products to understand,diagnose,and predict changing land,water,and climate,and their interactions and feedbacks over the geographic domain of the Mackenzie and Saskatchewan River Basins in Canada.The network operates a set of 14 unique and focused Water,Ecosystem,Cryosphere and Climate(WECC)observatories within this region,which provide opportunities to observe and understand processes and their interaction,as well as develop and test numerical simulation models,and provide validation data for remote sensing products.This paper describes this network and its observational,experimental,and modelling programme.An overview of many of the recent Earth system changes observed across the study region is provided,and some local insights from WECC observatories that may partly explain regional patterns and trends are described.Several of the model products being developed are discussed,and linkages with the local to international user community are reviewed—In particular,the use of WECC data towards model and remote sensing product calibration and validation is highlighted.Some future activities and prospects for the network are also presented at the end of the paper.

Patterns of brain injuries associated with maxillofacial fractures and its fate in emergency Egyptian polytrauma patients

Purpose： Maxillofacial injuries are commonly encountered in the practice of emergency medicine. More than 50% of patients with these injuries have multisystem trauma that requires coordinated manage- ment between emergency physicians and surgical specialists in oral and maxillofacial surgery, otolar- yngology, plastic surgery, ophthalmology, and trauma surgery. The aim of this study is to identify the patterns of brain injuries associated with maxillofacial trauma and its outcome. Methods： This descriptive study （cross-sectional） was carried out among 90 polytrauma patients with maxillofacial fractures attending the Emergency Department at Suez Canal university Hospital and fulfilling our inclusion and exclusion criteria. Results： This study demonstrates the relation between type of maxillofacial fracture and type of trau- matic brain injuries in which the majority of patients with epidural hemorrhage presented with mid face fractures （60%）, while the minority of them presented with upper and lower face fractures （20% for each of them）. The majority of patients with subdural hemorrhage were associated with mid face fractures （75%）, the majority of patients with brain contusions associated with mid face fractures （75%）, and all of the patients presented by pneumocephalus were associated with mid face fractures （100%）. Conclusion： The results of this study confirm the value of quick diagnosis and early intervention, which is fundamental to prevent morbidity as well as mortality especially with regards to prevention of traumatic brain injury as even a short duration of hvpoxia and edema will lead to significant permanent neurological deficits.

The stars hang down over the great emptiness of the level plain, and the moon bobs on the running waters of the Great River： thirty years of New Era research on the essay

New Era research on the essay and other occasional writing already has a history of thirty years. For various reasons, however, such research has consistently been slighted and condemned. This article offers a systematic and comprehensive review and analysis of the last thirty years of research in this field in terms of writers and their works, research on special topics, and the construction of the history and theory of this genre, and explores the reasons why it has been slighted for so long. To deepen and broaden this research in the new century, we must exert ourselves in three areas： first, we must adopt a modern vision of criticism of the essay; second, we must ＂digest Western theories＂ and ＂Sinicize essay writing and research＂; and third, we must change our research methods and way of thinking. These three points not only offer an important dimension for understanding and solving contemporary issues relating to the essay, but also have methodological significance for research.

Direct estimation of the Solar acceleration using geodetic/astrometric VLBI observations

The secular aberration drift observed as the apparent proper motion of extragalactic radio sources is caused by the acceleration of the coordinate origin,the Solar System barycenter.So,the acceleration can be estimated as a global parameter by using the 30 years global geodetic/astrometric VLBI data.This estimation is independent of any kinematic or dynamic model of the Milky Way or statistics hypothesis.The estimated acceleration in the direction of the Galactic center is (0.80±0.04) cm·s-1 ·yr-1,while the other two components are (0.0-1±0.06) and (0.52±0.05) cm ·s-1 ·yr-1 in the direction along the Solar motion in the Galactic plane and in the direction normal to the Galactic plane,respectively.The estimate of the acceleration independently provides another kinematics parameter without referring to any objects within the Galaxy.
