In 2009, nearly 900 million international tourist arrivals were counted worldwide. A global activity of this scale can be assumed to have a substantial impact on the environment. In this contribution, five major aspects such as the change of LUCC and the use of energy and its associated impacts had been recognized. Recently, the impact of tourism on environment and climate attracts the attention of international organizations and societies in pace with rapid development of tourism industry. Energy consumption and CO₂ emissions in tourism sector are becoming a hot spot of international tourism research in recent five years. The use of energy for tourism can be divided according to transport-related purposes (travel to, from and at the destination) and destination-related purposes excluding transports (accommodation, food, tourist activities, etc.). In addition, the transports, accommodation and foods are related to many other industries which are dependent on energy. Thus, the estimations of energy consumption and CO₂ emissions in tourism sector have become a worldwide concern. Tourism in China grows rapidly, and the number of domestic tourists was 1902 million in 2009. Energy use and its impact on the environment increase synchronously with China's tourism. It is necessary to examine the relationship between energy use and CO₂ emissions. In this article, a preliminary attempt was applied to estimate the energy consumption and CO₂ emissions from China's tourism sector in 2008. Bottom-up approach, literature research and mathematical statistics technology were also adopted. According to the calculations, Chinese tourism-related may have consumed approximately 428.30 PJ of energy in 2008, or about 0.51% of the total energy consumptions in China. It is estimated that CO₂ emissions from tourism sector amounted to 51.34 Mt, accounting for 0.86% of the total in China. The results show that tourism is a low-carbon industry and also a pillar industry coping with global climate change, energy-saving and CO₂ emission reduction. Based on this, the authors suggested that tourism should become an important field in low-carbon economic development.

The metropolitan resources comprehensive efficiencies (also called comprehensive technical efficiency, short for CTE, thereafter), change trends and causes are investigated using DEA and Malmquist index models, respectively, in China during the period 1990-2006. Firstly, the DEA model results show that the metropolitan CTE was just fair to middling with the characteristics of almost declining from the Eastern Coastal to Western China, and only few metropolises were DEA efficient. Secondly, the results also show that the PTE was correlated with the urban population sizes of metropolises negatively, and the SE correlated positively with the urban population sizes of metropolises in 1990, 2000 and 2006, that is, with urban population sizes getting larger the corresponding PTE was decreasing accordingly, and the SE was increasing consequently and the increasing rate was smaller with the scale increase. Thirdly, the influencing factors of metropolitan efficiency were SE and PTE in 1990 and 2000, respectively. But the PTE became the predominant influencing factor with the rapid expansions of built-up areas and population scales of metropolises in 2006. Fourthly, the Malmquist index results show that the CTE change trends were increasing weakly, the technological change trends were declining, and the TFP change trends were declining obviously during 1990-2006, in which they were all increasing during the sub-period 1990-2000, and all decreasing during the sub-period 2000-2006. Fifthly, the Malmquist index results also demonstrate that the CTE change trend was increasing weakly in the Eastern Coastal China, declining in Central China, and declining evidently in Western China. And with the urban population size increasing the increasing trends of SE became weaker and weaker. And the main causes for the CTE being not too high and its change trends and TFP change trends being increasing weakly lie mainly in the technological degeneracy and PTE change trends declining significantly during 2000-2006. Finally, the analyses show that the China's metropolitan population boom and the rapid spread of built-up area had really caused their resources efficiency losses.

For the low price of coal and ineffective environmental management in mining area, China is in the dilemma of the increasing coal demand and the serious environmental issues in mining area. The more coal that is exported from a region, the more heavily it suffers from the environmental impacts of coal export. In this paper, the temporal and spatial process of exporting coal from Shanxi to other provinces of China is traced between 1975 and 2005. The coal net export of Shanxi increased to 370.69 million tonnes in 2005, representing an average annual growth rate of 7.5% from 1975 to 2005. With the increase of the amount of coal export from Shanxi, the Environmental Loads Transfer (ELT) that import provinces input to mining areas of Shanxi are rising. Effective means of internalizing the environmental externality of ELT lie in: 1) setting up a coal sustainable development fund to restore environment of coal mining area; 2) enforcing environment tax, financial transfer payment and transferring advantage technology of pollution reduction to coal export area; and 3) reducing coal regional flow by reducing coal demand from power generation and heating and other industries.

The Annual Meeting of China's Geographical Journals Editing was held in Fuzhou city on April 21-25, 2011. This meeting was co-sponsored by the Working Committee for Editing and Publication under The Geographical Society of China (EPWC, GSC) and Fujian Normal University. The theme of the meeting was "Innovation and Development of the Geographical Journals in China".
