Effects of Human Activities in the Wei River Basin on the Lower Yellow River, China
Pol. J. Environ. Stud. Vol. 26, No. 6 (2017), 2555-2565 DOI: 10.15244/pjoes/70629 ONLINE PUBLICATION DATE: 2017-08-31 Original Research Effects of Human Activities in the Wei River Basin on the Lower Yellow River, China Li He Key Laboratory of Water Cycle and Related Land Surface Processes, Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, 100101 Beijing Received: 15 March 2017 Accepted: 22 April 2017 Abstract Water and soil conservation practices in the Wei River Basin (WRB) may in��uence the Lower Wei River (LWR) itself and the Lower Yellow River (LYR), of which the Wei is a tributary. Based on data of measured and natural runoff and suspended sediment load (SSL) in the WRB, the connections between runoff and SSL from the WRB and deposition in the LWR, the elevation of Tonggguan Hydrology Station, and deposition in the LYR are analyzed. For the compound effects of human activity and climate change in the WRB, the amount of deposition reduction in the LWR during 2000-2009 is about three times what it decreased dur- ing 1970-1979. For per square kilometers of soil conservation, the effect of human activities in the WRB on deposition in the LWR during period of 2000-09 is about four times that of the period of 1970-1979. As decreased runoff and SSL from the WRB, deposition in the LYR decreased during the periods of 1970-1979 and 1990-1999, while deposition in the LYR increased during the periods of 1980-1989 and 2000-2009. For the planned reservoir in the Jing River Basin, the decreased deposition in the LYR may be smaller than that of the LWR. -

Jun Xu Received: 13 May 2016; Accepted: 26 July 2016; Published: 3 August 2016 Abstract: Nitrate contamination in rivers has raised widespread concern in the world, particularly in arid/semi-arid river basins lacking qualified water. Understanding the nitrate pollution levels and sources is critical to control the nitrogen input and promote a more sustainable water management in those basins. Water samples were collected from a typical semi-arid river basin, the Weihe River watershed, China, in October 2014. Hydrochemical assessment and nitrogen isotopic measurement were used to determine the level of nitrogen compounds and identify the sources of nitrate contamination. Approximately 32.4% of the water samples exceeded the World Health Organization ´ (WHO) drinking water standard for NO3 -N. Nitrate pollution in the main stream of the Weihe 15 ´ River was obviously much more serious than in the tributaries. -

Xiao Gang (503-551): His Life and Literature
Xiao Gang (503-551): His Life and Literature by Qingzhen Deng B.A., Guangzhou Foreign Language Institute, China, 1990 M.A., Kobe City University of Foreign Languages, Japan, 1996 Ph.D., Nara Women's University, Japan, 2001 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF Doctor of Philosophy in The Faculty of Graduate Studies (Asian Studies) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) February 2013 © Qingzhen Deng, 2013 ii Abstract This dissertation focuses on an emperor-poet, Xiao Gang (503-551, r. 550-551), who lived during a period called the Six Dynasties in China. He was born a prince during the Liang Dynasty, became Crown Prince upon his older brother's death, and eventually succeeded to the crown after the Liang court had come under the control of a rebel named Hou Jing (d. 552). He was murdered by Hou before long and was posthumously given the title of "Emperor of Jianwen (Jianwen Di)" by his younger brother Xiao Yi (508-554). Xiao's writing of amorous poetry was blamed for the fall of the Liang Dynasty by Confucian scholars, and adverse criticism of his so-called "decadent" Palace Style Poetry has continued for centuries. By analyzing Xiao Gang within his own historical context, I am able to develop a more refined analysis of Xiao, who was a poet, a filial son, a caring brother, a sympathetic governor, and a literatus with broad and profound learning in history, religion and various literary genres. Fewer than half of Xiao's extant poems, not to mention his voluminous other writings and many of those that have been lost, can be characterized as "erotic" or "flowery". -
To Increase the Benefits of Water Investment for Regional and National Development ---A Case Study of Shaanxi Province
Global Water Partnership(China) WACDEP Work Package Three Outcome Report To increase the Benefits of Water Investment For Regional and National Development ---A case study of Shaanxi Province Research Office of Shaanxi Provincial People’s Congress Shaanxi Provincial Water Resources Department Xi’an Jiaotong University Copyright @ 2016 by GWP China Abstract Water is not only the indispensable and irreplaceable natural resources for human survival and development, but also very important strategic resources. Water is the infrastructure and the basic industry of the national economic and social development. With the economic growth, the pressure on scarce resources and ecological environment protection is highlighted. The need for government at all levels to speed up the water investment and improve people's welfare is pressing. Therefore, a comprehensive assessment of water investment in Shaanxi Province is of great practical significance. Relatively speaking, Shaanxi Province is short of water resources with less total amount and per capita share. In addition, the spatial distribution of water resources is also extremely unreasonable: the southern part of Shaanxi Province which is part of the Yangtze River basin takes up over 70% while the northern part which is highly populated with fast industrial development only shares 30% of it. The conflict between the demand for water resources and the distribution, to some extent, restrict the social and economic development. The Shaanxi Provincial Government has put the water sector in an important place. It is even so from 2010 to now with a dramatic increase on investment, reaching a total investment amount of 22.408 billion RMB in 2013. -

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%. -

Emergence of Pan-River-Basin A river basin (or watershed) is the area of land where surface water, including rain, melting snow, or ice, converges to a single point at a lower elevation, usually the exit of the basin. From the exit, the water joins another water body, such as a river, lake, reservoir, estuary, wetland, or the ocean. -
Geochemistry and Environmental Assessment of Major and Trace Elements in the Surface Sediments of the Wei River, China
Journal of Dynamic Article LinksC< Environmental Monitoring Cite this: J. Environ. Monit., 2012, 14, 2762 www.rsc.org/jem PAPER Geochemistry and environmental assessment of major and trace elements in the surface sediments of the Wei River, China Y. M. Han,*ab J. J. Cao,a F. Wu,a B. C. Zhang,a C. L. Zhan,abc C. Weiabc and Z. Z. Zhaoabc Received 4th April 2012, Accepted 15th August 2012 DOI: 10.1039/c2em30269a The development of western China in the past decade has led to increased discharges of wastewater and river pollution. The Wei River is the largest tributary of the Huang He River, but its geochemistry has not been thoroughly investigated. Sixty-three bed-surface sediment samples were collected from the Wei and analyzed for 24 elements by WDXRF; objectives for the study were to investigate the geochemical properties of the sediments; identify sources, and assess pollution levels and environmental risks. Major and trace element concentrations were comparable with those in other large rivers in China, but potentially hazardous trace elements (PHTEs) were lower than in the Yangzi or Pearl Rivers; most likely due to dilution of contaminants by the large sand inflows into the Wei and a lower level of industrialization. Nonetheless, pollution and risk analyses demonstrate slight contamination of Cr, Mn, Nb, Ni and Zn, moderate contamination of Cu and Pb, and strong contamination of As at some locations. Adverse biological effects from Ni and Cu are possible and are likely from As. Statistical and spatial analyses indicate that agriculture runoff and industrial wastewater discharge contribute to the contamination of this river. -
Comprehensive Evaluation of Water Resources Carrying Capacity in the Han River Basin
water Article Comprehensive Evaluation of Water Resources Carrying Capacity in the Han River Basin Lele Deng 1, Jiabo Yin 1,2, Jing Tian 1, Qianxun Li 1 and Shenglian Guo 1,* 1 State Key Laboratory of Water Resources and Hydropower Engineering Science, Wuhan University, Wuhan 430072, China; [email protected] (L.D.); [email protected] (J.Y.); [email protected] (J.T.); [email protected] (Q.L.) 2 Hubei Provincial Key Lab of Water System Science for Sponge City Construction, Wuhan University, Wuhan 430074, China * Correspondence: [email protected] Abstract: As one of the most crucial indices of sustainable development and water security, water resources carrying capacity (WRCC) has been a pivotal and hot-button issue in water resources planning and management. Quantifying WRCC can provide useful references on optimizing water resources allocation and guiding sustainable development. In this study, the WRCCs in both current and future periods were systematically quantified using set pair analysis (SPA), which was formulated to represent carrying grade and explore carrying mechanism. The Soil and Water Assessment Tool (SWAT) model, along with water resources development and utilization model, was employed to project future water resources scenarios. The proposed framework was tested on a case study of China’s Han River basin. A comprehensive evaluation index system across water resources, social economy, and ecological environment was established to assess the WRCC. During the current period, the WRCC first decreased and then increased, and the water resources subsystem performed best, while the eco-environment subsystem achieved inferior WRCC. The SWAT model projected that the amount of the total water resources will reach about 56.9 billion m3 in 2035s, and the water resources development and utilization model projected a rise of water consumption.
