Abstract: Ecological security is the basis of the sustainable development. Based on the concept of ecological security, The framework and subsystems’ functions of decision support system for mining area’s ecological security are put forward. The support system, which gets data by methods of remote sensing(RS),geographical information system(GIS),global positioning system(GPS), survey data, statistics data and experiment data, being mainly composed of database management system, knowledge management system and models management system, can make regulating and controlling decision for mining area’s ecological security.

Abstract: The development of low-carbon economy has opened a new chapter in environmental accounting and become a new direction of it. This paper analyzes the status of environmental accounting, describe the necessity of implementing environmental accounting, conclude new requirements that low-carbon economy poses on environmental accounting by combining them and finally give some suggestions for how to promote the development of environmental accounting.

Abstract: A La-doped Cu₁₁O₂ (VO₄)₆ photocatalyst with optimum La/Cu molar ratio of 4% was prepared by sol-gel method. XRD,SEM and EDX have been employed to characterize the as-synthesized materials. During liquid phase photocatalytic degradation of MO under the UV-light, the as-prepared La/ Cu₁₁O₂ (VO₄)₆ exhibits higher activity than the pure Cu₁₁O₂ (VO₄)₆. It found that the La/ Cu₁₁O₂ (VO₄)₆ prepared with the La/Cu molar ratio of 4% and calcinated under 500°C for 4 hours was pure triclinic phase. In this conditions, the sample had highest photocatalytic activity with the photodegradation rate was about 92.45% or so in 60min under 20W UV light.

Abstract: The ceramic industry is known as an energy-consuming and high pollutive industry. In order to meet the requirement of sustainable development, It is imperative to implement technology of energy conservation and emission reduction in the ceramic industry. Based on the production process in the architectural ceramic industry, this essay primarily discusses various energy-saving technologies, energy conservation and emission reduction, and construction of the low-temperature-fast-firing remodeling project flow chart. By analyzing the relevance of related technologies, it is hoped to make a significant contribution to the sustainable development of the ceramic industry.

Abstract: By means of non-aqueous solvent, V-type amylose-hexanol complex which B-type microcrystalline starch made a combination with hexanol was prepared. Study the influence of the reaction temperature, dropping time and cooling temperature on the V-type complexes’ crystallinity. The optimal synthetic conditions were found through the single factor experiment as follows：reaction temperature at 70°C, dropping time of 6min, cooling to room temperature. V-type complex was prepared under optimum conditions, the highest crystallinity reached 73.7%.

Abstract: This paper studies the low carbon transition of electricity system in China. The paper describes the approach, which builds on transitions and transition management using a multi-level perspective (MLP) of niches, socio-technical regime and landscape. A MLP analysis on China’s power sector is presented to understand the current landscape, regime and niches. Five transition pathways with their possible technology options are presented. The paper goes further to propose an interactive management framework for low carbon energy system transition in China and reprehensive technology options are appraised to indicate the policy package design logic in the framework. The work in the paper will be useful in informing policy-makers and other stakeholders and may provide reference value for other countries for energy transition management.

Abstract: As one of the most developed provinces in China, Shandong has consumed large amount of energy and released a lot of CO₂ during the economic development. Moreover, the power industry has consumed more than half of the energy and released the most CO₂. In order to explorer the situation of carbon emissions in Shandong province, investigation and demonstration have been done based on the present power structure situation. The investigation and study result indicated that the low carbon development route and strategy in Shandong could be divided into two ways: making full use of the new clean energy and developing power generation technology with high efficient.

Abstract: The characteristics of climate warming in China are investigated by using observed daily surface temperatures at 541 gauge stations from 1960 to 2010 and monthly pressure and air temperature from NCEP/NCAR reanalysis dataset. The results show that the temperature exhibits an ascending trend regardless of regions, underlying surface situations, seasons and atmosphere layers for the past 50 years, but warming rate is higher in north, west, urban district, winter and low atmosphere layer than that in south, east, suburb, summer and mid atmosphere layers, respectively. Afterwards analyzed is the interrelation of temperature variation, Siberian high and land use. Finally the connection between environmental destruction and climate warming is discussed based on the following process, viz., climate warming leads to frequent occurrence of extreme weather and climate events as droughts and floods, which can cause geological disasters and destroy the environment.

Abstract: Under the pressure of resource and environmental constraints, China proposed to develop strategic emerging industries in order to transform economic development mode and response to the economic and environmental crises. Strategic emerging industries are a new concept. This paper firstly summarizes its content. Then we conduct a comparative analysis between China and some developed countries. We can get the following conclusions: China is not a leader country in the development of new emerging industries; China’s choice in strategic emerging industries is consistent with developed countries; Industry competitive, in essence, is the technology competition. Finally, we give some suggestions.

Abstract: A capillary electrophoretic assay for determining synthetic antioxidant butylated hydroxyanisole in food has been developed. The extraction with 70% (v/v) methanol quantitatively extracted synthetic antioxidant. The separation was carried out by CZE using phosphate at a separation potential of 18 kV. Amperometric detection was achieved with an applied potential of 0.60 V. A linear relationship between the peak height and the concentration of the analyte was found in the range 1.8-180 µg/mL for BHA, with correlation coefficient of 0.994. The relative standard deviations of migration time and peak height were 0.19 and 5.3 %, respectively. The method developed was successfully applied for the determination of synthetic antioxidant butylated hydroxyanisole in food. Recovery of butylated hydroxyanisole was 93%.
