Many accidents of releasing toxic pollutants into surface water happen each year in the world. It is believed that dam cooperation can affect flow field in reservoir and then can be applied to avoiding and reducing spread speed of toxic pollutants to drinking water intake mouth. However, few studies investigated the effects of dam cooperation on the spread characteristics of toxic pollutants in reservoir, especially the source reservoir for water diversion with more than one dam. The Danjiangkou Reservoir is the source reservoir of the China’ South-to-North Water Diversion Middle Route Project. The human activities are active within this reservoir basin and cyanide-releasing accident once happened in upstream inflow. In order to simulate the spread characteristics of cyanide in the reservoir in the condition of dam cooperation, a three-dimensional water quality model based on the Environmental Fluid Dynamics Code (EFDC) has been built and put into practice. -

China's Past, China's Future Energy, Food, Environment
China’s Past, China’s Future China has a population of 1.3 billion people, which puts strain on her natural resources. This volume, by one of the leading scholars on the earth’s biosphere, is the result of a lifetime of study on China, and provides the fullest account yet of the environmental challenges that China faces. The author examines China’s energy resources, their uses, impacts and prospects, from the 1970s oil crisis to the present day, before analyzing the key question of how China can best produce enough food to feed its enormous population. In answering this question the entire food chain – the environmental setting, post-harvest losses, food processing, access to food and actual nutritional requirements – is examined, as well as the most effective methods of agricultural management. The final chapters focus upon the dramatic cost to the country’s environment caused by China’s rapid industrialization. The widespread environ- mental problems discussed include: • water and air pollution • water shortage • soil erosion • deforestation • desertification • loss of biodiversity In conclusion, Smil argues that the decline of the Chinese ecosystem and environ- mental pollution has cost China about 10 per cent of her annual GDP. This book provides the best available synthesis on the environmental conse- quences of China’s economic reform program, and will prove essential reading to scholars with an interest in China and the environment. Vaclav Smil is Distinguished Professor in the Faculty of Environment, University of Manitoba, Canada. He is widely recognized as one of the world’s leading authorities on the biosphere and China’s environment. -
Henan Dengzhou Integrated River Restoration and Ecological Protection Project: Sector Assessment (Summary): Agriculture, Natural
Henan Dengzhou Integrated River Restoration and Ecological Protection Project (RRP PRC 52023) SECTOR ASSESSMENT (SUMMARY): AGRICULTURE, NATURAL RESOURCES, AND RURAL DEVELOPMENT A. Sector Road Map 1. Sector Performance, Problems and Opportunities 1. Dengzhou City in Henan Province, part of the Han River Watershed in the Yangtze River Basin, is a national key ecological function zone designated by the government. Although the city area is within the Yangtze River Economic Belt (YREB), its contribution to the YREB is critical.1 The city, with an area of 2,369 square kilometers and a population of 1.8 million, is located in the headwater zone of the middle route of the South–North Water Diversion Project, which transfers water from Danjiangkou Reservoir through a 1,277-kilometer (km) stretch of canal to 30 water- 2 deprived northern cities, including Beijing in the Beijing–Tianjin–Hebei region. 2. Water resources management. As the economy of the People’s Republic of China (PRC) continues to grow, propelled by rapid industrialization and urbanization, the demand for water is growing as well. For the medium-growth scenarios (i.e., a medium socioeconomic growth scenario and a moderately intensive water conservation scenario), total annual projected water supply in the PRC from all sources is expected to reach about 700 billion cubic meters (m3) by 2030, an increase of 99 billion m3 compared with the 2014 base year water supply. The middle route of the water diversion project has started to divert 10 billion m3 of fresh water annually from the Han River in Dengzhou City to water-scarce northern areas, benefiting more than 100 million people. -

They can pose a risk of inundation to a human habitat but can also be utilized as a resource with hydraulic engineering. Improving the knowledge of flood characteristics is the basis and premise of improving water resources management and ecological environmental protection. Presently, the quantitative evaluation of flood characteristics needs to gradually evolve from a single indicator to a systematic one. In this paper, by introducing the concepts of ecohydrology on magnitude, frequency, and duration, a set of flood characteristics indicators evaluation system is constructed based on the hydrological characteristics for the section where Danjiangkou Reservoir is located at the middle reach of the Yangtze in China. The results showed that the Danjiangkou Reservoir has changed the flood characteristics to a great extent both of seasonal or annual floods, and the mean degree of the flood characteristic alteration indicators is about 19%. The changing trend of the flood indicators upstream showed an increasing trend from the 1970s to 2010s, while downstream were divided into two periods by the year of about 1975. -
New Discovery of Rock Art and Megalithic Sites in the Central Plain of China
Rock Art Research 2012 - Volume 29, Number 2, pp. 157-170. TANG H. 157 KEYWORDS: Cupule – Rock art – Megalith – Cross-dating – Central Plain of China NEW DISCOVERY OF ROCK ART AND MEGALITHIC SITES IN THE CENTRAL PLAIN OF CHINA Tang Huisheng Abstract. Since the turn of this century, an immense amount of rock art has been discovered in Henan Province (located in the Central Plains region of China), centred at Mt Juci. Over 90 percent of the rock art consists of cupules and the remainder comprises linear groove patterns, chessboard-like designs and other motifs. The rock art features mainly ground motifs and patterns chiselled by metal tools. There are a variety of cupules, varying in size, depth and arrangement, e.g. occurring in rows, concentric patterns and so on. Rock art was executed on over 10 000 boulders, some of which could be classified as megalithic sites, such as menhirs, dolmen, ‘stone altars’ and the like. The cupules and the megaliths from the Central Plains region appear to show a structural context, which will help us to understand and identify their cultural nature, contents and ages. Based on cross-dating, their production could be considered as spanning the Neolithic and the Bronze Age. Since the turn of this century, a large quantity of a considerable surprise — not only to rock art studies, rock art has been discovered at Mt Juci, in Henan Pro- but also to archaeological studies and studies of early vince (located in the Central Plains region of China), Chinese history. Herein, we introduce the rock art of which has captured public attention and stimulated the Central Plain based on information mainly from Mt extensive interest in rock art studies. -

In China’s reservoir context, increasing concerns have arisen regarding distant- resettlees (those who are resettled outside the reservoir area), while fewer studies have examined the nearby-resettlees (those who are resettled near the original area) and the non-movers (those who do not resettle). The significance of these two groups has been downplayed and their populations are in the millions (or more) in China. How and why they are impacted is under-researched and their relative position and intergroup nexus with the distant-resettlees remains unclear in the existing literature. To address this research gap, this paper incorporates the differences between nearby- resettlees and non-movers and collectively refers to them as the “stayers” as they are left behind in Citation: Jiang, T.; Wang, M.; Zhang, reservoir areas. -
Moving the River? China's South–North Water Transfer Project
Chapter 85 Moving the River? China’s South–North Water Transfer Project Darrin Magee 85.1 Introduction China is not a water-poor country. As of 1999, China’s per capita freshwater avail- ability was around 2,128 m3 (554,761 gallons) per year, more than double the internationally recognized threshold at which a country would be considered water- scarce (Gleick, 2006). The problem, however, is that there is no such thing as an average Chinese citizen in terms of access to water. More specifically, the geo- graphic and temporal disparity of China’s distribution of freshwater resources means that some parts of the country relish in (and at times, suffer from) an over-abundance of freshwater, whereas other parts of the country are haunted by the specters of draught and desertification, to say nothing of declining water quality. The example of China’s Yellow River (Huang He) has become common knowledge. The Yellow takes its name from the color of the glacial till (loess) soil through which it flows for much of its 5,464 km (3,395 mi) journey (National Bureau of Statistics, 2007). After first failing to reach the sea for a period during 1972, it then suffered similar dry-out periods for a portion of the year in 22 of the subsequent 28 years (Ju, 2000). The river so important for nurturing the earliest kingdoms that came to comprise China, once known as “China’s sorrow” because of its devastating floods, now has become a victim of over-abstraction, pollution, and desert encroachment, and a symbol of the fragility of the human-environment relationship on which our societies depend.
