Measuring Chinese Marine Environmental Efficiency:A Spatiotemporal Pattern Analysis

Environmental efficiency standards are often used to evaluate the costs of oceanic economic development. A variety of statistical analyses were applied in this study to quantify the marine environmental efficiency of 11 Chinese coastal provinces and municipalities between 2000 and 2014. Results initially reveal that environmental efficiency measures that incorporate undesirable outputs are more consistent with real production conditions and thus the use of marine economic and environmental efficiencies supplement and complement one another. Second, overall marine environmental efficiency across China tends to be low and can be spatially characterized by a transformation such that the inefficiencies noted in 2000 have subsequently been transformed to comprise a three-tiered structure that encompasses northern, central, and southern cores. Third, variation in absolute and relative marine environmental efficiency differences for the coastal regions of China have been consistent over time; values initially decreased before increasing again in a fluctuating manner over the time period of this analysis. Fourth, data show that the Pearl River Delta area has experienced the highest rate of change in marine environmental efficiency over time when economic zones are used as basic research units, although values have nevertheless fluctuated significantly. Fifth, values for total factor productivity as well as technical efficiency and change across the Chinese marine economy all fluctuated over time but increased. Data show that changes in marine environmental efficiency across China can primarily be attributed to progress in marine science and technology. Finally, levels of capital investment and marine industrial pollution intensity are not significantly correlated with marine environmental efficiency. Indeed, both marine industrial structural levels and environmental protection technologies have had a positive effect on environmental efficiency while levels of investment in marine scientific research as well as the scale of economic development, the marine economy, and the degree of external openness have all exerted negative effects on this key variable.

Community attitudes toward ecotourism development and environmental conservation in nature reserve:a case of Fujian Wuyishan National Nature Reserve,China

Using social exchange theory, this study investigated residents＇ attitudes toward the preliminary stage of tourism development in nature reserves in Wuyishan National Nature Reserve of China, and the socio-economic and negative effects of residents＇ attitude toward the tourist industry. Results of the questionnaire survey indicated that local people perceived they could benefit from the economic activities related to tourism, and were supportive of the conservation of natural resources and local culture, sustainable community development, and community participation in ecotourism planning and management. This study also revealed that the variables of age, gender, education level, household income, family size, non-farm work arrangements, and the distance to tourism attractions, have significant association with respondents＇ attitudes toward ecotourism development, or negative impacts of the tourist industry. Respondents who are male, or have a higher household income, are more supportive of tourism development inside the reserve. Younger and more highly educated community members are more likely to support learning more about natural and cultural resources and landscapes. Respondents who have a hieher household income, or live far fromthe village center, are more concerned about the negative environmental impacts of tourism development.

Effectiveness of Bark Extracts and CeO2 Nano Particles as Coating Additives for the Protection of Heat-Treated Jack Pine

High temperature heat-treatment of wood, which is value-added green product, is one of the altematives to chemical treatment. It has better dimensional stability, thermal insulating properties and biological resistance compared to kiln dried wood. It also has dark brown color which is very important for decorative purposes. Unfortunately, this color changes during weathering. Developing a transparent and non-toxic coating for the protection of heat-treated wood against discoloration without changing its natural appearance is the main objective of this study. For this purpose, waterborne acrylic polyurethane base was chosen because of its durability against weathering and non-toxic nature. Natural antioxidants which are extracted from barks and CeO2 nano particles （alone or together with lignin stabilizer） were used as additives to develop different coatings. The protective characteristics of these coatings were compared with highly pigmented and toxic industrial coating under accelerated weathering conditions. The results showed that acrylic polyurethane coatings protected wood better compared to commercially available coating tested in this study. The chemical modifications during accelerated weathering of coated and heat-treated wood surfaces were monitored by X-ray photoelectron spectroscopy analysis. The morphological changes took place during weathering were studied by fluorescence microscope analysis.

Development of Reaction Process with the Consideration of Environmental Impact Minimization

A methodology is presented to identify environmental impact minimization alternatives for reaction processes and assess their environmental performance. The potential environmental impact (PEI) scheme can be used to visibly display the transformation relationships among different types of PEI, identify the sources of environmental impacts, and propose alternatives for eliminating or minimizing the impacts. To evaluate the environmental performance of the alternatives effectively, some new indices, such as PEI input rate of non-products, PEI output rate of non-products per profit and the PEI conversion efficiency are proposed. Finally, the application of the methodology is illustrated using an industrial case study.

Develop hydroenergy resources and protect earth environment

Energy is a driving force behind the progress of human civilization. Mainly depend on the current human society of non-renewable fossil energy sources, such as coal and oil, its increasing demand. Gradually reduce the reserves, the contradiction between supply and demand becoming increasingly prominent. With the process of human history has moved forward with the depletion of fossil energy will eventually be unable to sustainable use. The total hydropower resources are limited, but it is renewable, clean energy, its energy is infinite. Therefore, the full use of limited water resources and slow down the depletion of fossil energy process, is to improve and protect the earth’s ecology and environment, one of the most realistic measures.

Research on propagation law of AE wave in coal seam

Based on mechanism of AE creation, put forward sphere cavity model, and deduced wave Equation of AE wave radiated by the AE source in detail, and analyzed the propagation attenuation law of AE stress wave in coal （rock） strata. Displacement function of AE wave indicates that displacement field can be divided into two parts. Firstly, displacement of particle is approaching to the source intensity function in zone near the AE source. Secondly, in zone far away from the AE source, displacement of particle is approaching to the derivative of source intensity function. AE wave changes gradually in the spreading process, and notable change of the wave form happens when wave propagates far away from the AE source.
