Nansihu is the largest lake of Shandong Province in China. It has a strategic significance because of its locating on the East Route Project of South to North Water Diversion. In 2004, the supplying water was about 3.10 × 108m3 and the water demand was about 2.56 × 104m3. Although the supplying water can satisfy requirement, the situation was not optimistic. At the same time, the total water resources...
High economic growth in Shandong has had huge implications for great water consumption and produced significant water pollutants. Saving index is introduced to analyze the evolution of the performance of water consumption, waste water discharges, COD (Chemical Oxygen Demand) and ammonia nitrogen emissions in Shandong over the past 12 years. The change of saving indexes represents Shandong's water...
Lack of safe drinking water is a major problem in rural areas, it also persists in places like irrigation districts. this study was carried out to establish the accessibility of water in rural areas of Jinghuiqu Irrigation District(JHQID). In these areas, main sources of water for domestic purposes were groundwater and the piped water coverage rate was low, only 1,204,500 residents got their drinking...
An environmental impact method based on numerical simulation is proposed and the assessment of environmental impact caused by dam-break is gained. According to the dam-break flood simulation results, the routing process of dam-break flood is concluded. Then the environmental risk evaluation model is built based on the obtained hydraulic factors. Qing Linjing reservoir located in Shenzhen of China...
Di-(2-ethylhexyl) phthalate (DEHP) is one of the typical endocrine disrupting chemicals found in water and wastewater. Concentrations of DEHP in water, wastewater and reclaimed wastewater are summarized based on published literatures. Concentrations of DEHP in source water for drinking or final sewage effluents sometimes definitely exceeded legal stipulations for DEHP limits in China. Although physicochemical...
Protecting the environment and achieving water security, and taking the road of sustainable development, which is the necessary request for fulfilling the scientific outlook on development fully, and the fundamental guarantee for establishing harmonious society. We should explore a new idea of controlling pollution which can integrate the administrative measures, market forces and public participation...
The Jing Hang Grand Canal of China is the longest and earliest water conservancy project in the world. Its total length is more than 1,790 kilometers, 10 times longer than the Suez Canal, 20 times longer than the Panama Canal, and it is the world's longest man-made canal. It goes through 2500 years since Chinese Spring and Autumn period as an inland river, which had played an important role in the...
The operation of gold mine enterprise is a complex systems engineering, the production flows, this article will applies the recycling economy theory in the production of gold mineral, seeks to fundamentally prevent and efforts to reduce or lower the influence of the production process of gold mineral improves the quality of the environment, solves environmental problems of china's gold mine, achieves...
The Partnership for University Research Abroad (PURA), a group of interdisciplinary students at the University of Virginia, has formed a partnership with Tzununa, a community on the shores of Guatemala's Lake Atitlan, to address its water quality needs. Faced with the need for a water filtration system, Tzununa has consented PURA's implementation of a point-of-use water filtration system. Utilizing...
The traditional GDP calculation system neglects the cost of natural resources and environment. It can't effectively embodies the correlation between the economic development and the environment and resources. Practice of the Green National Economic Accounting, measuring and guiding the national economy with the index sign of Green GDP, not only can reflect the economy growth level, but also the diapason...
With the rapidly development of the economic, environmental problem has become one of the most prominent problems of the society. Lake water environmental problem became more and more serious, and it had seriously effect on human health and the socio-economic sustainable development. It is a key project to find a more effective way of water pollution control. An intelligent decision support system...
Urban areas are complex ecosystem of interacting social, economic, and natural components, dominated by human activities. Wetlands are an important part in urban ecosystem as they play an important role in the health and sustainable development of urban ecosystems. This paper discusses the concept of ecological service function in the face of wetland decline, and possible strategies for wetland conservation.
Nowadays, the environment risk of mining area is a very serious problem. And mining area environmental impact of a variety of uncertainties, from the engineering point of view can be divided into land pollution, water pollution, air pollution, noise pollution and solid waste pollution. In the paper, an evaluation index system of mining area risk is established by using the triangular fuzzy number...
Water resource in China is scare, non-balanced distribution and polluted very severely. Water problem has become the key obstacles for the sustainable development of China. The comprehensive evaluation of urban water security is the foundation for carrying out the strategy and plan of urban water security. In this paper, the index system of urban water security evaluation is established and the index...
The present study will examine the possible ways of integrating sustainability indicators in measuring the performance of agriculture. I am examining the appropriate ways of calculating the output of the sector including the damages caused by and the benefits of agricultural production. First, I present the almost 40 years old history of how to integrate the environmental components in the calculation...
In this paper, the concept of industrial ??Skeleton-Infill?? (SI) house was described, and the characteristics of SI houses as construction durability, adaptability and suitability for industrial production were summarized. Based on data collection and spot investigation of industrial Skeleton-Infill house of VANKE which is one of the top three real estate company in China, the author discussed the...
Sustainability has become a popular word since the last decades, but a practical approach to evaluate sustainability not existed. The evaluation of sustainability in water management needs criteria/indicators and objectives, which define what is good or bad. For comparing sustainable water management alternatives an evaluation method to integrate and rank calculated indicators is needed as well. The...
Jiaozuo mining area emit significant amount of mine water per year, most of which lost in vain in the absence of scientific management and planning. On the one hand, water resource of Jiaozuo is acutely short; on the other hand, mine water was wasted and environment was polluted. Based on the analysis of the hydro-geological conditions as well as mine water inflow for a nearly decade in Jiaozuo mining...
In the Quanzhou coastal area, groundwater plays a necessary role in domestic use, but the groundwater use does not receive enough attention by water managers up to now. As the irrational groundwater use in the recent years, groundwater quality becomes much worse. The main problems include groundwater contamination and seawater intrusion. It should be noted that existing rich faults provide the formation...
A water balance model is established in this paper. The relationship between water requirement and lake ecosystem is built and reflected by the appropriate water level to protect lakes and wetlands. And some measures of controlling human management action with water limit are put forward by the example of the Baiyangdian Lake.
