Based on TM remote sensing images in 1989, 2000 and 2008, combining with GIS technology, and the city of Beijing's land use change characteristics in the past 20 years from 2008 will be analyzed. The indicators such as single land use dynamics, land utilization classification index and land use transfer matrix will be used to reveal the changes on range, speed and direction of this study area. On...
The cumulative effect of air pollution could be caused by the factors of time accumulation, space transfer, weather conditions and new air pollutant resulting from chemistry reactivity of several pollutants. In order to analyze the control strategies of the cumulative effect of air pollution, the analytic network process (ANP) is embedded into SWOT for a best quantitative alternative. Finally, an...
According to economic analysis, the city road have exist its own supply and demand, the papers put forward the ways of relaxation of traffic jam. If want to relax the city traffic jam, we can interweave the measures as follows: lead the demand of citizen in peak load periods, developing the public traffic and appropriate city layout so that increase the supply of road.
Energy is the essential pillar of the national economy. Either the shortage or interruption of the energy supplement will threaten the security of our national economy, directly. With the rapid development of our national economy, China has become more and more dependent on energy. It exposes our country to the serious challenges in this area. At present, over 90% of the national imported energy supplement...
The EMD method was introduced to study the fluctuation of production and consumption of energy in China at multi-time scale from 1949–2008. Through the method of EMD, the fluctuations or trends in the different time level were unbundled to produce a series of different characteristics of the intrinsic mode functions and the system had the evolution curves on a different time scale, which could be...
To further promote the study of the carbon sinks and the quantitative analysis of fixing carbon and releasing oxygen of Phyllostachys pubescens which was the principal bamboo species in subtropical area, diurnal variations net photosynthetic rate were measured using photosynthesis methods in this study. The results showed that: there were obvious differences in carbon fixation and oxygen release among...
With the development of economic globalization, corporate social responsibility has become a research focus. Firstly, based on Carroll's social responsibility theory, the scope of corporate social responsibility, including economic responsibility, legal responsibility, ethical responsibility and philanthropic responsibility (or self-responsibility), was defined.

Land resource security has come to be a popular issue, and the researches mainly focus on static evaluation of the level of land resource security. But the growing lack of land resource caused by various factors requests us turning our researches on land resource security to dynamic adjustment and control urgently. This paper describes a specific directed graph model on which the model of land resource...
Based on remote sensing and ecological survey data, paper selected eight categories of typical ecological factors, defined the grades and weight of their impact on the ecological environment, and assessed the ecological sensitivity of Taierzhuang with GIS technology and weighted superposition method. Ecology sensitivity of land was divided into five categories through fuzzy clustering and consolidation...
Soil erosion causes both on-site and off-site impacts that contribute to economic loss of different extent. On-site impacts include losses of sediments, soil nutrients and water; whereas off-site impacts include soil detainment and siltation, respectively. Based on the date of the remote sensing survey on the soil erosion in Linyi City, monetary loss caused by soil erosion were calculated using different...
The present study involved two key procedures: (1) Input-output table including energy consumption is built and some parameters, such as coefficient of industrial correlation, energy consumption per unit of output value and elasticity ratio of energy consumption, are calculated. (2)Based on characteristics of industrial correlation and energy consumption four industry classes (I, II, III, IV) are...
Hebei Province is facing a long-term water shortage problems. Over-exploitation of water resources caused great ecological and environmental problems. This situation restricted social and economic sustainable development of the province. Under the constraints of water resources, the industrial structure had been adjusted, resulting in maintaining sustainable social and economic development while saving...
The objectives to improve the management system of China's land resources are: First, the coordination of farmland protection, ecological protection and the relationship between non-agricultural land; The second is to coordinate between the central government and local government relations; Third, to coordinate the public interest and the personal interests of farmers relations; Fourth, to achieve...
As the national survey of pollution sources revealed, the proportion of agricultural pollution has increased, and the problems of rural eco-environment should arouse wide concern. As a major agricultural province, the current situation of rural eco-environment is far from optimism, which has restricted the sustainable development of rural economy, society and environment. To change this situation,...
From the perspective of manufacturing location choice, this paper analyzed the reasonableness of spatial distribution of transportation infrastructure and transportation investment allocation in China. The study found that there is too much unreasonableness in the spatial distribution of transportation infrastructure and allocation of transportation investment, and it has not been effectively improved...
Based on the model of population carrying capacity under the condition of opening region, from the two aspects of resources and economy, the absolute and relative population carrying capacity in lin yi city is analyzed, the results show that the population of lin yi city has been at a serious overloading condition, such as sustainable growth of population, situation of stagnant economic development,...

In Shared-Savings EMC projects, EMCo bears almost all the risks, including those of external environment, energy-saving technology, marketing, organization and management, and customer. Therefore, Risk prevention and risk management is especially important for EMCo. This article analyzes the features of Shared-Savings EMC's risks, apply subjective grading method to make a qualitative analysis, and...
The deterioration of traditional environmental problems has threaten the human security in worldwide and the environmental security has come into being. Inrecent research status of environmental security, the authors put a new research concept that researching the environmental security problems in perspective of macro-security. Environmental security, considered as one of the important branches of...
This paper takes Wuxi as a case study and analyzing the characteristics of urban expansion from the viewpoint of urban scale and urban structure, here we emphasize that urban spatial expansion is not only build-up area increase, but also the change land use structure. We further explain the reasons that have given rise to these changes. We conclude this case study with some observations on the impacts...
