Acid rain can bring a lot of damage to the ecological environment of the earth and social economy of human. Studies show that acid rain is harmful to soil, waters, forest, buildings and scenic spots. It not only brings heavy economic loss, but also affects the survival and development of human severely. The SO2 in the atmosphere is the leading source of acid rain. Now People pay more and more attention...
With the acceleration of urbanization process and the growth of motor vehicles in China, transportation, environment and energy issues have become important issues of urban development, and developing rail transportation is one of the main ways to solve the urban problems. This paper analyses China's basic urban rail transit situation, the supply and demand of urban rail transit and the choice of...
Climate change has become one of the most serious challenges our human being has to face, and this issue is extremely urgent in China due to the large population and fast industrialization. Renewable energy can provide a major solution to mitigate global warming, and wind power can occupy an important position in the future power matrix due to wind resource distribution, wind power industry development...
This paper studies the relationship among service industry, urbanization and economy growth of China since the reform and opening up by establishing a multi-variable econometric model and using the Johanson cointegration test and impulse response function. We found that the service development and economic growth affected each other in both directions in the long-term, and the economic growth raises...
At present in China, local governments have tried various financing approaches. This paper uses principal component analysis to assess the efficiencies of four financing methods which are commonly used by the local governments. The result shows that the efficiency of local bonds financing is higher than that of land financing, platform financing and financial allocation by the central. Platform financing...
The central government of China draw out an important policy "Pothook of City Construction Land Increase and Rural Residential Land Decrease", which has been carried out in many districts allowed by the government, to alleviate the supply-demand contradiction of landuse. This paper analyzes the method to assess rationality of the project of Pothook of City Construction Land Increase and...
Based on a large volume of relevant documents on smart grid, the paper summarized current developing situation of smart grid, including the definition and character description in Europe, America and China. It pointed out that because of different development environment and drive force, different countries' power grid enterprises and organizations comprehend the smart grid concept variously. The...
Climate change policy and position drives the transition to a low carbon economy, creating opportunities and risks to which businesses must respond to succeed.This paper presents the key policy drivers by sector and summarise the international policy shaping China position. It studies provide in depth analysis of key issues to inform businesses and policy makers on how to address climate change and...
China's gross amount of hydraulic resource ranks first in the world; however, at present, China's economic development faces energy bottleneck. Huge market demands, as well as the strategy of western development, provide hydropower with an opportunity and a broad development prospect. At the same time, some negative influence on environment and ecology also give hydropower development with unprecedented...
The future of electric power is smart grid, one of the key parts is smart substation. The Technical guide for smart substation is published by State Gird Corporation of China for the construction of smart substation and Tri-status measuring and control device which includes the steady state measure, transient state measure and dynamic state measure is presented. The uniformed source data with the...
The purpose of this paper is to detect the input condition and technical efficiency of grape production in China, and compare the production condition between Open-field Cultivation and Protected Cultivation using the frontier approach. The results show the mean technical efficiency is about 0.79 suggesting that 0.21 of the potential production is lost in Chinese grape production. Meanwhile, the technical...
In order to present a more reasonable means for the development of China's urban rail transit system, the present thesis, adopting methods of diachronic comparison and synchronic comparison, analyses the system structure, the differences between the Chinese and the overseas, and the development trend of urban rail transit systems after processing a large number of data of both home and abroad. The...
Fuel cells are highly efficient and environment friendly. China are studying and developing these technologies actively. Presents the developing history of fuel cell in China, then fuel cell technologies in China are discussed in detail, including proton exchange membrane fuel cell (PEMFC), solid oxygen fuel cell (SOFC), melt carbonate fuel cell (MCFC) and alkalescency fuel cell (AFC). A prospect...
In view of the difficult interoperations, information sharing and barely reused among existing power quality software and systems, this paper presents a power quality aided service platform which by using multi-agent technology can dynamically compose basic web services to implement advanced power quality aided service functions and meet the rapidly changing business demands flexibly. The aid service...
With China's rapid economic development and the world's total primary Energy declining, Energy bottleneck effect on China's economy has become increasing evident. China's economic growth pattern is in the transitional period from extensiveness to intensiveness, the improvement of the energy structure also becomes more urgent. In this paper, the authors put forward some measures to adjust China's energy...
Solar radiation data is essential to the work of energy planners, engineers and agricultural scientist. In this study, the solar radiation model was developed using the measurements from the 101 solar radiation observation stations in China. The average daily radiation on horizontal surfaces in 621 meteorological stations was estimated by the model with the sunshine hours and geographic information...
In this paper, stormwater runoff from an urban traffic road and building located in Beijing, China, was characterized to measure the stormwater runoff discharge rates and pollutant concentrations. Based on monitoring, the runoff water quality on two underlying surface conditions was analyzed. The temporal dynamics of chemical oxygen demand (COD), NH3-N, NO3-N and total phosphorus (TP) were similar...
China enjoys rich lignite resources. However, the development and utilization level of lignite in China is low compared with other countries. The lignite in China is distributed mainly in the eastern areas of Inner Mongolia and in the northeast provinces. The characteristics of China's lignite are closely related to its coal-forming age. Due to the shallow buried coal seams, most parts of the lignite...
Biodiversity has become an internationally central concern. As such, it is crucial to fully consider it into social economy development. This paper explores how to carry out the biodiversity impact assessment (BIA) as a useful tool for biodiversity conservation. Taking Beibu Gulf economic zone as the case, the study predicts the impact of the industrial development plans for the period 2007-2020....
Solar energy is rich, ideal for the sustainable use of renewable clean energy, solar photovoltaic system utilizes photovoltaic effect of solar cells and transforms the solar radiation directly into electricity generation. In the world most countries focus on such new power generation form. In recent years China has made great progress in using solar energy and photovoltaic technology. The production...
