Gu Yuxuan, Shijiazhuang Foreign Language School Shijiazhuang, Hebei Province, China China, Factor 6: Sustainable Agriculture
Gu Yuxuan, Shijiazhuang Foreign Language School Shijiazhuang, HeBei Province, China China, Factor 6: Sustainable Agriculture China: Sustainable Land Use on Sanjiang Plain Located in the northeast corner of China, Sanjiang Plain is in the administrative divisions of Heilongjiang Province. Amur River, Ussuri River and Songhua River joining together, with their waves impacting the soil, formed this flat and fertile alluvial plain whose total area is 108,900 square kilometers. The surface is wet and always has surplus water because of the broad and flat terrain. The cold and wet climate condition causes heavy precipitations in summer and autumn. Rivers run slowly with sudden flood peak periods. Seasonal freezing-thawing soil covers the whole plain. All those account for large areas of swamp water and vegetation which involves 2.4 million hectares of swamp and marsh soil, ranking China’s largest swamp area. Ten wetland nature reserves were set up, attracting many international ecological and environmental protection organizations. The region, which is covered with 10 to 15 cm of water and the total quantity is 18.764 billion cubic meters, is home to many first-class national protected animals. For instance, the red-crowned cranes in the IUCN (World Conservation Union) red list, the Chinese merganser and the Siberian tiger all find their habit in this plain. Sod layer soils are thick, generally 30 to 40 cm. In the area lies the most fertile black earth in China, and it’s one of the three black earth terrains in the world. High in organic matter, the organic matter is 3% to 10%. -

Religion in China BKGA 85 Religion Inchina and Bernhard Scheid Edited by Max Deeg Major Concepts and Minority Positions MAX DEEG, BERNHARD SCHEID (EDS.)
Religions of foreign origin have shaped Chinese cultural history much stronger than generally assumed and continue to have impact on Chinese society in varying regional degrees. The essays collected in the present volume put a special emphasis on these “foreign” and less familiar aspects of Chinese religion. Apart from an introductory article on Daoism (the BKGA 85 BKGA Religion in China prototypical autochthonous religion of China), the volume reflects China’s encounter with religions of the so-called Western Regions, starting from the adoption of Indian Buddhism to early settlements of religious minorities from the Near East (Islam, Christianity, and Judaism) and the early modern debates between Confucians and Christian missionaries. Contemporary Major Concepts and religious minorities, their specific social problems, and their regional diversities are discussed in the cases of Abrahamitic traditions in China. The volume therefore contributes to our understanding of most recent and Minority Positions potentially violent religio-political phenomena such as, for instance, Islamist movements in the People’s Republic of China. Religion in China Religion ∙ Max DEEG is Professor of Buddhist Studies at the University of Cardiff. His research interests include in particular Buddhist narratives and their roles for the construction of identity in premodern Buddhist communities. Bernhard SCHEID is a senior research fellow at the Austrian Academy of Sciences. His research focuses on the history of Japanese religions and the interaction of Buddhism with local religions, in particular with Japanese Shintō. Max Deeg, Bernhard Scheid (eds.)

List 3. Headings That Need to Be Changed from the Machine- Converted Form
LIST 3. HEADINGS THAT NEED TO BE CHANGED FROM THE MACHINE- CONVERTED FORM The data dictionary for the machine conversion of subject headings was prepared in summer 2000 based on the systematic romanization of Wade-Giles terms in existing subject headings identified as eligible for conversion before detailed examination of the headings could take place. When investigation of each heading was subsequently undertaken, it was discovered that some headings needed to be revised to forms that differed from the forms that had been given in the data dictionary. This occurred most frequently when older headings no longer conformed to current policy, or in the case of geographic headings, when conflicts were discovered using current geographic reference sources, for example, the listing of more than one river or mountain by the same name in China. Approximately 14% of the subject headings in the pinyin conversion project were revised differently than their machine- converted forms. To aid in bibliographic file maintenance, the following list of those headings is provided. In subject authority records for the revised headings, Used For references (4XX) coded Anne@ in the $w control subfield for earlier form of heading have been supplied for the data dictionary forms as well as the original forms of the headings. For example, when you see: Chien yao ware/ converted to Jian yao ware/ needs to be manually changed to Jian ware It means: The subject heading Chien yao ware was converted to Jian yao ware by the conversion program; however, that heading now -
Polycyclic Aromatic Hydrocarbons in the Estuaries of Two Rivers of the Sea of Japan

The PAH levels were generally low over the year; however, the PAH concentrations increased according to one of two seasonal trends, which were either an increase in PAHs during the cold period, influenced by heating, or a PAH enrichment during the wet period due to higher run-off inputs. The major PAH source was the combustion of fossil fuels and biomass, but a minor input of petrogenic PAHs in some seasons was observed. Higher PAH concentrations were observed in fresh and brackish water compared to the saline waters in the Tumen River estuary, while the PAH concentrations in both types of water were similar in the Partizanskaya River estuary, suggesting different pathways of PAH input into the estuaries. -
Report on Shanghai Water Projects
Consulate General of Switzerland in Shanghai Commercial Section ISSUE NO.4 July 2003 Report on Shanghai Water Projects ‘A glass of water with half a glass of dirt’ was the vivid picture of the quality of drinking water in Shanghai some 25 years ago. People could still clearly remember the strange taste of the water at that time. Half a century’s industrialisation not only led to Shanghai’s fast development, but also to serious environmental problems. As the Chinese saying goes, a city with a river running through it is a city full of life. But this cannot be applied to Shanghai. Having two heavily polluted rivers running across the city, the Huangpu River and the Suzhou Creek, Shanghai has to deal with two problematic water currants. Back to even five years ago, walking along the famous Bund area was not a pleasant experience because of the bad smell emanating from the Huangpu River. For people living close to the Suzhou Creek, the situation was even worse. People had to keep windows closed day and night to avoid the foul smell from the water in the neighbourhood. Instead of being green and clear, the Creek was black and opaque, full of sewage. The drinking water for urban residents is seriously polluted as it comes mainly from outlying sections of these two rivers - the upper stretch of the Huangpu River near the Songpu Bridge in Minhang District, and the river mouth where the Yangtze River merges with the East China Sea. Faced with the threat of worsening water pollution, and demands of meeting international environmental standards, the Shanghai government decided to adopt measures for improving the environmental situation in the city. -

The Current Status of Environmental Criteria for Hydropower Development in the Mekong Region: A literature compilation Foreword Population growth, economic development, and associated increases in personal wealth are causing growth in electricity demand across the Greater Mekong region, if not uniformly within the different countries, still at an overall rapid rate for the region as a whole. Different sets of options are open to meet this demand – each with unique advantages and disadvantages - all of which become entangled in the complex play of diverging priorities supported by different interest groups. In the mean time, the recent recognition of the role of human activities on climate change is leading to rethinking of the entire energy sector. As a result, a complex paradigm lies in front of decision makers, touching on crucial issues such as global -
Soil Heavy Metal Contamination Assessment in the Hun-Taizi River Watershed, China Wei Zhang1, Miao Liu2 ✉ & Chunlin Li2
www.nature.com/scientificreports OPEN Soil heavy metal contamination assessment in the Hun-Taizi River watershed, China Wei Zhang1, Miao Liu2 ✉ & Chunlin Li2 The Hun-Taizi River watershed includes the main part of the Liaoning central urban agglomeration, which contains six cities with an 80-year industrial history. A total of 272 samples were collected from diferent land use areas within the study area to estimate the concentration levels, spatial distributions and potential sources of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn) with a geographic information system (GIS), principal component analysis (PCA) and canonical correspondence analysis (CCA). Only the concentration of Cd was over the national standard value (GB 15618–2018). However, the heavy metal concentrations at 24.54%, 71.43%, 63.37%, 85.71, 70.33%, 53.11%, and 72.16% of the sampling points were higher than the local soil background values for As, Cd, Cr, Cu, Hg, Ni, Pb and Zn, respectively, which were used as standard values in this study. The maximal values of Cd (16.61 times higher than the background value) and Hg (12.18 times higher than the background value) had high concentrations, while Cd was present in the study area at higher values than in some other basins in China. Cd was the primary pollutant in the study area due to its concentration and potential ecological risk contribution. The results of the potential ecological risk index (RI) calculation showed that the overall heavy metal pollution level of the soil was considerably high. -
INDIAN & WORLD GEOGRAPHY ASTRONOMY 1. What Is the Difference Between Asteroids and Comets?
INDIAN & WORLD GEOGRAPHY ASTRONOMY 1. What is the difference between asteroids and comets? (2011) 1. Asteroids are small rocky planetoids, while comet are formed of frozen gases held together by rocky and metallic material. 2. Asteroids are found mostly between the orbits of Jupiter and Mars, while comets are found mostly between Venus and Mercury. 3. Comets show a perceptible glowing tail, while asteroids do not. Which of the statements given above is/are correct? (a) 1 and 2 (b) 1 and 3 (c) 3 (d) 1,2 and 3 Ans: B The biggest difference between comets and asteroids is what they are made of. While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When comets get closer to the Sun, they lose material with each orbit because some of their ice melts and vaporizes. Asteroids typically remain solid, even when near the Sun. Right now, the majority of asteroids reside in the asteroid belt, a region between the orbits of Mars and Jupiter which may hold millions of space rocks of varying sizes. On the other hand, the majority of comets are in the farthest reaches of our Solar System: either 1. in the Kuiper Belt — a region just outside the orbit of the dwarf planet Pluto that may have millions of icy comets (as well as many icy dwarf planets like Pluto and Eris); or 2. the Oort Cloud, a region where trillions of comets may circle the Sun at huge distances of up to 20 trillion kilometers (13 trillion miles). -

Academic Editor: Jamal Jokar Arsanjani Received: 10 July 2016; Accepted: 17 October 2016; Published: 21 October 2016 Abstract: Source apportionment of river water pollution is critical in water resource management and aquatic conservation. Comprehensive application of various GIS-based multivariate statistical methods was performed to analyze datasets (2009–2011) on water quality in the Liao River system (China). Cluster analysis (CA) classified the 12 months of the year into three groups (May–October, February–April and November–January) and the 66 sampling sites into three groups (groups A, B and C) based on similarities in water quality characteristics. Discriminant analysis (DA) determined that temperature, dissolved oxygen (DO), pH, chemical oxygen demand (CODMn), 5-day biochemical + oxygen demand (BOD5), NH4 –N, total phosphorus (TP) and volatile phenols were significant variables affecting temporal variations, with 81.2% correct assignments. Principal component analysis (PCA) and positive matrix factorization (PMF) identified eight potential pollution factors for each part of the data structure, explaining more than 61% of the total variance. -
Impact of Changes in Land Use and Climate on the Runoff in Dawen River Basin Based on SWAT Model - 2849
Zhao et al.: Impact of changes in land use and climate on the runoff in Dawen River Basin based on SWAT model - 2849 - IMPACT OF CHANGES IN LAND USE AND CLIMATE ON THE RUNOFF BASED ON SWAT MODEL IN DAWEN RIVER BASIN, CHINA ZHAO, Q.* – GAO, Q. – ZOU, C. H. – YAO, T. – LI, X. M. School of Water Conservancy and Environment, University of Jinan 336 Nanxinzhuang West Road, Jinan 250022, Shandong Province, China (phone: +86-135-8910-8827) *Corresponding author e-mail: [email protected]; phone: +86-135-8910-8827 (Received 8th Oct 2018; accepted 25th Jan 2019) Abstract. A distributed hydrological model (SWAT), which is widely used both domestically and internationally, was selected to quantitatively analyze the impact of land use and climate change on runoff in this paper in Dawen River Basin, China. The calibration and validation results obtained at Daicunba and Laiwu hydrological stations yield R2 values of 0.83 and 0.80 and 0.73 and 0.69 and the Ens values of 0.79 and 0.76 and 0.71 and 0.72, respectively. Taking 1980-1990 as the reference period, the annual runoff increased by 288 million m3, which was caused by changes in the land use of basin from 1991 to 2004, whereas the annual runoff decreased by 132 million m3 due to climate change. Land use changed from 2005 to 2015, which resulted in an increase in annual runoff of 13 million m3, and annual changes in climate caused a decrease in annual runoff of 61 million m3. An extreme land use scenario simulation analysis shows that, compared to the current land use simulation in 2000, the runoff of cultivated land scenarios and forest land scenarios was reduced by 38.3% and 19.8%, respectively, and the runoff of grassland scenarios increased by 4.3%.
