Authors: Lü Yong Peng , Che Yue , Shang Zhao Yi , Yang Kai
Published: September 2013

Vegetation in coastal parks is more sensitive and fragile to subsoil salinity. 600 subsoil samples in a newly-developed coastal park and 1800 subsoil samples in three old non-coastal parks in Shanghai, China were collected. The subsoil salinity of coastal park is 4.83 times higher than that of non-coastal parks. The average subsoil salinities in Spring and Winter are higher than that in Summer and Autumn. Collaborative vertical trend of subsoil salinity for four seasons is significant (p<0.05). Therefore, the ditches should be adjusted for salt elimination according to location of highly saline plaques, and seepage interception projects should be set up between green-space and unimproved land and the vegetation should be watered more frequently in Spring than that in other seasons.

Succinoglycan is an acidic exopolysaccharide that is important for invasion of the nodules. It is a high-molecular-weight polymer consisting of repeating octasaccharide units. These units are synthesized by a complex pathway encoded by numbers of exo genes. In this study, two key genes,exoAandexoY, were cloned and sequenced, which controlled the first two glycosyltransferase reactions in the biosynthesis of succinoglycan. The sequences contained 999-base-pares (bp) and 681-bp Open reading Frame (ORF) encoding 332 and 236 amino-acid proteins with molecular weights of approximate 36.8 kDa and 25.5 kDa , respectively. The putative proteins, ExoA and ExoY, were analyzed by several online protein analysis softwares. The results showed ExoA and ExoY were the membrane proteins with three (ExoA) and one (ExoY) hydrophobic transmembrance domains. Their theoretical PI values were 9.49 and 9.34, respectively. The second structures analysis indicated that they were composed of 45.48% and 38.94% α-helix, 13.55% and 16.81% β-sheet, and 40.96% and 44.25% random coil structures respectively. These data will lay a foundation for the subsequent 3D structure prediction and gene mutation to improve succinoglycan production.

Authors: Chang Yan Yan , Lin Chang Song , Zhou Xin Huai , Xia Shi Qiang
Published: September 2013

In Liaozhong Depression, five types of sublacustrine fans are developed in the relative lowstand systems tracts of the fourth-order sequence in Dongying Formation. In drilling cores, typical turbidites characteristics exist including bedding structures such as slump deformation structure, parallel bedding, grading laminations and multi-stage scoured basal surfaces. They also can be recognized in well logs with distinctive low gamma-ray and high-resistivity stacking patterns. Logging curves usually display serrated bell shape, cylinder shape and funnel shape respectively. On seismic reflection profiles, sublacustrine fan typically shows lateral downlap on its external geometry and continuous or discontinuous “vermicular” reflection characteristics in its inner seismic reflection texture. According to the calibration results of drilling data, continuous seismic reflection profiles are interpreted to be mud-rich deposits with cohesive, soft sediment-deformation. Discontinuous seismic reflections with lateral migration and apparent incised valleys are interpreted to be sand-rich deposits which probably host the most potential litho-stratigraphic traps.

Study on Acoustic Emission Evolution Characteristic of Plastic and Brittle Coal Failure Process
Authors: Yang Hui Ming
Published: September 2013

Under uniaxial compression loading, the failure experiments of plastic and brittle coal are carried out to study the acoustic emission evolution characteristic. The results show that the evolution of acoustic emission during the coal failure process corresponds with the process of coal crack initiation, propagation and coalescence. The acoustic emission event rate of the typical plastic coal displayed the variation of up-peak-down during the failure process. The event rate of acoustic emission increase sharply and then drop steadily is the precursor that the main crack plane of the plastic coal would coalescence and the coal will lose its stability. During the failure process of typical brittle coal, the event rate increased steadily with the increase of stress, showing the variation of up-peak; the down stage of acoustic emission is not obvious because the brittle coal suddenly fail after stress peak. The study results can provide a theoretical basis for explanations of the variation of acoustic emission and the establishment of instability criteria in coal and rock stability monitoring engineering by AE technology.

Authors: Chaiittipornwong Taksina , Malakul Pomthong , Wiwattnadej Dawan
Published: September 2013

The paper presents evidence-based evaluation of a sustainable production of one-way bottled drinking water in Thailand with emphasis on open-loop and close-loop processes. Two groups of producers were selected: four top brands and four house brands. In-depth interviews and plant surveys were conducted to explore the producers performances in four categories: corporate social responsibility (CSR), sustainable design, 3 Rs principle and life-cycle management (LCM). The interview and survey transcripts were combined, analyzed and categorized for two sustainable production measures: resource efficiency and pollution reduction. Three most prominent findings are that the top brands moderately perform the sustainable production while the house brands do less well, the resource efficiency measure is much more valued than the pollution reduction, and that the LCM is the most favored category, unlike the CSR. In conclusion, both brands are challenging for improving water efficiency and increasing plastics recyclability and the close-loop process shall be largely adopted among Thai bottled water producers.

Authors: Tang Jian Jun , Li Shao Feng
Published: September 2013

The effects of crystalline structure (Anatase and Rutile) and H2O2 addition on TiO2 visible-light photocatalysis were studied, which used reactive brilliant red X-3B and phenol as model pollutants. The results indicated that reactive brilliant red X-3B could be degradated by the two form TiO2(anatase or rutile) under visible-irradiation with the assistance of H2O2, however, when the surface sites of TiO2 photocatalysts were preeminently occupied by CO32-, photodecomposition could not be processed. Phenol could also be degradated by the two form TiO2 under visible-irradiation with the assistance of H2O2, rutile TiO2 exhibited a better photocatalytic activity, and its degradation ratio could be 80% after 120 min of reaction. The concentration of the ring intermediates detected during phenol decomposition was evidently higher when using rutile TiO2 as photocatalyst, and the presence of hydroxyl radical inhibitor (tert-butyl alcohol or methanol) had great effects on the degradation efficiency of rutile TiO2, but had less effects on anatase TiO2. The degradation of phenol occurred mainly in the solution when using rutile TiO2 as photocatalyst, and in contrast, the degradation occurred mainly at the TiO2 particles surface when using anatase TiO2 as photocatalyst.

Authors: Chen Hsiao Wei , Liu Yen Lan
Published: September 2013

This paper examines the possibility of green fertilizer fallowing supporting eco (logical)-economicdecision-making in farmland management. Using scenario analysis and linear programming as research methods, this paper examines farmland allocations and fertilizer use in Taiwan under different economics perspectives and fallow subsidy rates. It is concluded that in agriculture development, reconciliation between the pursuit of profit and environmental sustainability is possible. However, it is not suggested that this reconciliation be achieved via high-level fallow subsidies. Rather, it is critical that the ecological economics view of decision-making be employed in farmland management.
CCS Can Make Fossil-Fueled Energy Clean in Guangdong Province, China
Authors: Zhou Di , Liao Cui Ping , Li Peng Chun , Huang Ying
Published: September 2013

CCS (Carbon Capture and Storage) is the only technology available to achieve a deep cut in CO2emissions from large-scale fossil fuel usage. Although Guangdong Province has less heavy industries and higher reliance on energy import compared with many other provinces in China, CCS is still essential for the low-carbon development in the province. This is because fossil fuel energy is now and will be in the foreseeable future the major energy in Guangdong. CCS may have other benefits such as helping energy security and bring new business opportunities. The feasibility of CCS development in Guangdong is ensured by the existence of sufficient CO2storage capacity in offshore sedimentary basins in the northern South China Sea. A safe CO2storage is achievable as long as the selection of storage sites and the storage operations are in restrict quality control. The increased cost and energy penalty associated with CCS could be reduced through technical R&D, the utilization of captured CO2, and the utilization of infrastructure of offshore depleted oil fields. Fossil fuel energy plus CCS should be regarded as a new type of clean energy and deserves similar incentive policies that have been applied to other clean energies such as renewables and nuclear.

A Comparison of Two Biomass Estimation Methods: A Case Study of Several Pine Forests in China
Authors: Li Fei , Zhang Hua Yong , Wang Zhong Yu , Zhang Li
Published: September 2013

Power function model and linear function model were commonly used to express the relationships between stand volume and biomass. However, the relative accuracy is still unclear. In order to compare the accuracy of the two types of model, field measurement data of 279 pine forest stands in China were collected from published literatures. Using the data collected, the relationships between stand volume and aboveground biomass (AGB) ofPinus koraiensisforest,Pinus armandiiforest,Pinus massonianaforest,Pinus tabulaeformisforest andPinusforest were established. The mean relative error and mean absolute values of relative errors were employed to test the errors of the established equations. The goodness-of-fit and errors of these two types of model were compared. The results show that the power function models could generally express the relationships better than the linear function models. Also, the errors of the power function models are generally lower than those of the linear function models.
Discussion on the Mining Pollution and Geologic Background in Yinyang Sea at the Northeast Corner of Taiwan
Authors: Wang Shih Chung , Chen Shu Fen , Shen Yun Hwei , Chen Chia Yon
Published: September 2013

The Yinyang Sea phenomenon in Liandong Bay at the northeast corner of Taiwan is regarded as being the result of pollution caused by ore refining by the Taiwan Metal Mining Corporation. The Taiwan Metal Mining Corporation has been closed since 1987; however, the phenomenon still exists. According to the research findings, the Yinyang Sea phenomenon in Liandong Bay is the result of natural weathering. The suspended substance in the bay is Fe (OH)3, which is not a pollutant announced by Environmental Protection Administration, and the Fe (OH)3is mostly caused by natural weathering reactions; this is why the Yinyang Sea phenomenon occurred before the foundation of the Taiwan Metal Mining Corporation and continues to occur 25 years after the closure of the mine. The distribution of various elements is not uniform, and the original geologic background values of many regions exceed present environmental standards. If the water quality and soil background data of different geologic environments in Taiwan are not investigated as soon as possible, the mining industry may be misrecognized as being responsible for environmental pollution due to unknown geologic anomalies, as Taiwan Metal Mining Corporation was, and this may cause meaningless disputes over economic development and environmental protection.
Can Japan's Outwards FDI Reduce its CO2 Emissions?: A New Thought on Polluter Haven Hypothesis
Authors: Yang Li Guo , Liu Yu Na
Published: September 2013

This study tests for the Granger causal relationship between Japan's CO2 emissions, outwards FDI and economic development. The results show that Japan's outwards FDI is the Granger cause of Japan's CO2 emissions and the effect is negative, which means when Japan increase outwards FDI, Japan's environmental state will get better. So, Polluter haven hypothesis is true for Japan and developing countries should enhance their environmental standards to stop absorbing Japan's pollution intensive FDI.

Published: September 2013

The depth variations of soil physicochemical properties in the degraded native grasslands and the artificially restored grasslands were studied in the Three-river headwater areas of Qinghai-Tibetan plateau, China. The results showed: (1) With the increase of the gradient of restoration years, soil water content, total chemical properties, total potassium, phosphorus, available phosphorus and potassium were increased thereafter in the artificial grasslands. (2) With the increase of grassland degradation gradient, soil water content was gradually reduced, and the total N, K, the organic matter didnt gradually reduced also. (3) Both restoration years and degradation degree didnt influence the nutrient distribution in soil. (4) The organic matter, total N and K of degraded grassland were increased by artificial grassland construction. Therefore, artificial grassland construction canbe used as an effective measure of ecological projects in the Three-river headwater area.
On Legal Systems for the Realization of Corporate Environmental Responsibility in China
Authors: Song Jin Hua , Xiao Wen
Published: September 2013

This paper explores the realization of corporate environment responsibility (CER) by legal system. The corporate production and management have an important effect on environmental problems, but it is difficult for enterprises themselves to carry out environmental responsibility. By the analysis of China's legal system concerned and the status quo of CER, it can be concluded that the realization of CER should be guaranteed by the arrangement and implementation of a series of legal systems, at least including implementing the Green Market Access system, improving the Corporate Environmental Information Disclosure system, propelling the Cleaner Production system, enforcing the Environmental Labeling system and establishing the Emission Trading system.
