Abstract: This paper analyses the relationship between China's economic growth and energy consumption of the period 1978-2009 by the Granger causality test. The results of the study show that: economic growth and energy consumption have cointegration relationship, energy consumption promote economic growth, but economic growth is not Granger caused the consumption of energy. In order to promote China's economic development, the reasonable energy consumption quantity must be found, It's a new topic.

Abstract: The content of 5-hydroxymethlfurfural (5-HMF) in glucose diphasic hydrolysate was measured by ultraviolet spectrophotometry (UV), while 5-HMF solution and distilled water was used as the standard sample and controlling blank instead of water-dimethylsulfoxide (DMSO) diphasic solution respectively, analyzing the content of 5-HMF at wavelength 284 nm. The determination results showed us a favorable linear relationship between the absorbance and the concentration of 5-HMF, when it is fall in between 0-0.10 mmol/L. This method is suitable for rapid and accurate determine 5-HMF.

Abstract: Low-carbon tourism, as a new tourism type, is evolved from the background of the low-carbon economy. Located in the west part of Gansu Province, Gannan is endowed with favorably inborn conditions for the development of low-carbon tourism, for its economic development is comparatively backward and the amount of incoming tourists is limited. The paper made an analysis on the base of existing tourism circumstances in Gannan, the frailty of its ecological environment and the destruction made by the tourists to prove the idea that development and persistence of low-carbon tourism in Gannan will push the sustainable development of the tourism further in this area. At the end of this paper, several practicable suggestions are advanced for the development of low-carbon tourism in Gannan.

Abstract: Tree-ring width chronologies were developed for Larix gmelini of main forest types in Daxinganling mountains, and by correlation analysis and response function analysis illustrate difference empact of main climate factors on radial growth of Larix gmelini. The result shows ring-width chronologies of Larix gmelini we have made containing a lot of climate informations. In the correlation analysis, impact of temparature on Larix gmelinii is higher than presipitation, average month temperature is negatively correlated with ring-width growth and correlation efficient is higher, especially February temperature is significantly negatively correlated with radial growth of Larix gmelini three forest types. Response functions analysis indicating that Bryaceae—Larix gmelinii forest is more sensitive to climate and the response is complex. The sensitivity are: Bryaceae—Larix gmelinii forest > Ledum palustre—Larix gmelinii forest > Bryaceae—Larix gmelinii forest.

Abstract: The Liuyang River Tunnel on Wuhan-Guangzhou High-Speed Railway goes through the bottom of Liuyang River, the geological condition of which wall rock is not suitable for the construction. The paper proposes the heading pre-reinforcement method, namely pre-reinforcing core soil ahead of heading with fiberglass rockbolt in construction in order to optimize the construction methods and avoid both the deformation inside the tunnel and surface subsidence, and to ensure safety of tunnel construction. In order to determine the reasonable construction parameters, the paper obtains reinforcement density and length of fiberglass rockbolt, pre-reinforcement method on outline of heading, excavation step length and other construction parameters, by the numerical simulation, the indoor model tests and other methods, and analyzes its sensitivity. It is shown by the practices in construction that the selected parameters are reasonable and significantly effective, thus providing valuable experience for promotion and application of heading pre-reinforcement method.

Abstract: This paper focuses on the compiling and the role of the socially responsible index. Socially responsible investment originated from ethically investing teachings and developed on growing social awareness. Social responsibility indexes are products of the development of social responsibility investment. The Domini 400 Social Index, the Dow Jones Sustainability Indexes and the Calvert Social Index are typical cases of international social responsibility indexes. They are compiled on the base of consistency, flexibility and transparency and their component stocks are selected according to triple bottom line. Compared with international experiences, China’s social responsibility indexes have a shorter history and some problems.

Abstract: The fragmentation pathway of acevaltrate was investigated by electro-spray ionization ion-trap mass spectrometry．Under the positive ion mode, pseudo-molecular [M+Na]⁺ could be easily obtained，and fragmentation pathway presented a certain regularity. One of the major fragmentations observed in the collision induced dissociation(CID) spectrum was loss of branched-chain, and the other was that three-membered oxygen-containing rings would break into aldehyde. These results might be used to forecast the structures of irodoids.

Abstract: On the basis of analysis the tourism developing background in Linxia, this paper puts forward the spatial strategic orientation. According to the conditions of tourism resources, traffic, market, regional functions etc, we establish the tourism spatial distribution of “one center, two poles, two belts, three districts”and the developmental thinking, for the purpose of developing the tourism scientifically in Linxia.

Abstract: QuEChERS is an acetonitrile partitioning and dispersive solid-phase extraction (D-SPE) method that widely used in the analysis of multiple classes of pesticide residues in vegetable and fruit. In this paper, we modified it to fulfill analysis on much more complex matrix-Chinese herbal medicine, and High Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) was chosen for analysis. This method could be applied to quantitative and qualitative analysis of a wide range of pesticides in Chinese herbal medicine (Fructus Aurantii Immaturus as sample).

Abstract: This article compiles the energy input-output tables for year 2002 and 2007. Based on the energy input-out tables, we compute the carbon emission volume of China and by sector. The article also analyzes the source and change of the emission volume, based on structural decomposition analysis. The article finds that there are five factors affect the carbon dioxide. Among which the change of emission intensity, domestic need are the main reason of the decrease of emission, while production technology, trading structure and scale effect increase the emission volume. We also find that although the direct emission intensity decrease during the study period, the complete emission intensity increase by an annual rate of 3.8%, which reflect the result of energy policy is not equal in different sectors. We cannot deny the technologic and economic linkages between sectors when establish an energy policy.
