The questions of planning in system of environmental management on a rail transport are considered in the article. The author offers model of a new system of environmental management on a rail transport, formulates its purposes and tasks for different levels of management, and considers the concept «ecological aspect» on the railway transport. Also the formula of calculation of coefficient of risk...
In water-scarce environments, surface water bodies serve both as water sources and waste disposal channels. The Molopo River that drains through Mafikeng, South Africa, has been dammed for agricultural and municipal water supply, resulting in four reservoirs near Mafikeng. It receives municipal waste water discharges from point pollution source sewage processing plants. In this study the spatial variation...
We present a new approach to monitoring public recreational beach waters and describe a prototype system that collects data from sensors and from people and combines those to create a novel metric of water resource quality and appreciation. We present an evaluation of the system and consider some consequences for IT-enabled smart environments that monitor shared resources in general.
The effect of foreign investment on six pollutants such as industrial polluted water, and sulfur dioxide is investigated with the regression model. The result shows that there isn't significantly negative correlation between the FDI and pollution emission, which is contrary to the popular hypothesis so called pollution haven. The environmental effect of FDI notably varies among different regions,...
This study was undertaken in Danjiangkou reservoir and the upper reaches, where the SWAT model was used to analyze the space distribution of non-point source pollution. The land-use pattern was interpreted by Environment for Visualizing Images Software (ENVI). The runoff and the sediment data series from 2001 to 2006 were collected to calibrate the parameters and validate the model. The calculated...
The risk assessment of drinking water source focused on quantitative assessment of contaminants detected in drinking water on human health risks, but the potential environmental risk assessment of source drinking water protection is rare research. Therefore, in this paper, expert systems and AHP were introduced into the conventional fuzzy comprehensive evaluation in order to improve the degree of...
The acceleration of urbanization is making the problem of environment pollution and the resources deficient more and more serious, while the drought and water shortage, flood disaster, etc., baffle the urbanization in turn. By summing-up the status of the utilization of urban rain-flood, the main problems of the utilization of urban rain-flood are analyzed. Furthermore, the measures to utilize urban...
Growing population and rapid economic development lead to increasing pollution loading and lowering water quality. Protection of water environments is our glory target; The key strategy is: combining management of the land-water system in catchment and realizing the quasi-non-pollution release in an as small as possible catchment area.”; developing the high technology for realizing this target in...
Nuclear, acting as the most potential development direction of electricity industry, has advantages such as clear, high efficiency, effective supplement to electricity industry development continuously. The environment protection of nuclear plant differing from thermal power plant is that the cleaning don't means hygiene maintaining simply, on the country, it means the rising of plant's environment...
Identification of water quality conditions in a river system based on limited observations is an essential task for meeting the goals of environmental management. Various classification methods have been used for water quality estimation. However, a discrepancy frequently arises from the lack of a clear distinction between each water utilization mode, the uncertainty in the quality criteria employed...
Environment and health are inextricably interlinked. The physical environment, such as drinking water, sanitation, housing, and air, has considerable effects on the health status and well being of people. Environmental change and its attendant health impacts are driven by many factors, including economic growth, population growth and movements. The three broad trends - the intensification of agriculture,...
The assessment of River water quality is the basis of water pollution control, environmental management and environment planning. In this paper, combining analytical hierarchy process(AHP) with fuzzy mathematics, we make a synthetic assessment of river water quality, the indicator system of fuzzy synthetic assessment of rive water quality is established. AHP is used to determine the weight of indicators...
Exponential smoothing method is the main quantitative prediction methods, using exponential smoothing method to forecast the development trend of water environment security would provide available scientific basis to guiding the water environment safety guarantee work. The main factor of exponential smoothing method is smoothing coefficient, which directly affect the accuracy of prediction. Based...
The major method of water quality monitoring was sampling in the scene at present in China. In response to the problems such as weak sampling capability of water quality, untimely data processing and so on, based on GPRS technology, the design scheme of an automatic water quality monitoring system is proposed. The system utilizes the water quality monitor to process the sample and send the relevant...
As a unique natural region unit and the "buffer zone" which connects reservoirs and its peripheral region, the reservoir shore zone not only provides geographical space and resources-environmental supporting conditions for the local socio-economic development, but also plays a "barrier" role in maintaining reservoir ecosystem services function and protecting the environmental security...
Water pollution in Taihu Lake has become one of the most serious environmental problems that draws public attention and needs to be solved as soon as possible. It was well known that forest could play an important role to control soil & water erosion, uptake extra soil nutrients as well. However forest coverage is rather low and woodlands are extensively managed in the headwaters region. Thus...
The increasing pollution load played a key role in the water quality deterioration and eutrophication of Lake Dianshan. The results of pollution surveys of 1985, 1995 and 2006 showed that the inputs of nitrogen and phosphorus from upper stream origin from Lake Taihu were up to 7565.0 t and 401.0 t in 2006, respectively, accounting for more than 90% of the sum; nitrogen input from non-point source...
Payment for watersheds services (PWS) is an important instrument of watersheds protection and management, which can transform fortune and reduce the inequity of environment and development between the upper reach and lower reach. Both government and market play a key role in the course. Based on case study of Jinhua River, the analysis on the payment mechanism and modes of environmental services and...
The coastal zone systems of Bohai Sea make a significant role in Bohai Sea region's economic development, which constitutes the Bohai economic circle support system. But with economic development, a series of pollution problems occur. This article points out Bohai Sea now has been seriously polluted and the pollution has already affected ecology. According to the present development, resources and...
This paper presents the construction of a fuzzy environmental quality index for decision support in municipal environmental management. Five groups of indicators were selected in order to obtain an equation that best represented reality in terms of environmental quality. The calculation was carried out using “fuzzy” mathematical concepts, with the aid of the package Fuzzy Logical Toolbox 2.1 for Matlab...
