Abstract: Low-carbon economy is a new path which our country is taking to develop economy. As one of the provinces in the southeast coast of China, Fujian develop a low-carbon economy directly relating to the transformation of its economic growth, conservation of energy, improvement of productivity, innovation of technology and so on. We can say that the development of low-carbon economy directly affects the sustainable development of economy and society in Fujian province of China. Therefore, firstly, we believe that government and enterprise should optimize the allocation of resource and improve the utilization of resource. Secondly, the tax policies are supposed to adjust to stimulate the development of environmental protection industry. Thirdly, government should accelerate the construction of infrastructures. Fourthly, the legal system needs to be built and perfected so as to promote the development of low-carbon economy. At last, the investment of techniques is supposed to increase to a certain degree, and the ability of innovation and management of enterprises should be promoted to adapt the development of low-carbon economy of Fujian province.

Abstract: Based on the actual data of Xiushan County and Chinese manganese demand, GM (1, 1) model was established to predict the manganese demand. The prediction accuracies of Xiushan’s manganese demand, Chinese manganese production and exports were respectively 95.5%, 94.5% and 96.3%. Residual error test showed that the model was reliable and could be used to predict the manganese demands in the future five years. And the demands would be grown exponentially with time. The predictive results indicated that the supply safeguard was worrying.

Abstract: Ecological quality, efficiency, safety, and fairness are the core components of an eco-city. The expansion and contraction of urban ecological territories impacts eco-cities in all of these four components. The central distance of an ecological territory is an indicator that measures its expansion and contraction. As the central distance increases, measurable changes in the four components change either predictably, smoothly, or erratically, with fluctuation. Regulating the expansion and contraction of an urban ecological territory is an effective way to achieve a balanced eco-city.

Abstract: The residual RHA from Vietnam is used to test the likely application in cement and concrete. The characteristics, quality and influence of RHA on the quality of concrete are investigated in this investigation. The workability, strength and durability of concrete added with ground RHA satisfy with the relevant standards and requirements. It indicates that the ground RHA in this study can be used as a good supplementary cementious material. Therefore, it is possible to obtain RHA concrete with comparable properties than those of the control specimen (without RHA) with a lower consumption of cement, thus reducing the CO2 emissions during the production of cement and the environmental and disposal problem of the ash can also be diminished. Moreover, while the results will be able to substantiate the viability of application of RHA in concrete industry under the prevailing conditions in Vietnam, they are also expected to be especially useful for future studies on RHA in a specific condition in this country.

Abstract: The development of Energy and Coal Chemical Industry Base (ECCIB) is not only the important impetus of the regional economy, but also the guarantee of national energy security. In the near future, China will develop seven Energy and Coal Chemical Industry Bases. Ningdong ECCIB is selected to be a typical case for the further analysis in the paper. The food web of Ningdong ECCIB is obtained based on the material metabolism analysis of ECCIB and the relative statistics of Ningdong ECCIB. Then it is evaluated by the associating relation rate and the waste recycling rate. It is concluded that the associating relation rate of Ningdong ECCIB is 0.378 which is higher than the average of the rate of the eco-industrial parks in China. The solid waste recycling rate of Ningdong ECCIB is 30.38%, while the waste water recycling rate is 28.17%. They are both relatively lower. Accordingly, several optimization countermeasures are proposed.

Abstract: The materials transportation system with storage bin is widely used in mines, power plants, material yards, and etc. Bin capacity size has great influence on reliability and production efficiency of whole materials transportation system. By utilizing some existing outcomes, this paper presents a new reliability and cost-benefit integrated optimization model about storage bin capacity in materials transportation system. Compared with some existed references, this presented model fully considers different influences of storage bin capacity on reliability and production efficiency of whole materials transportation system and realizes reliability, cost and benefit overall optimization decision. All kind of factors affecting designed storage bin capacity can be easily gotten by the presented model. In addition this paper also presents a set of detailed reliability and cost-benefit integrated optimization formulas about storage bin capacity in materials transportation system. These can offer the reference for capacity decision design computing of storage bin in materials transportation system.

Abstract: Under the background of fact that the shortage situation of present global being severer and severer day by day, the army equipment development faces enormous challenge. How to walk out a low-input, high-efficient road of equipment construction seems particularly important, which has been a great strategic task of the modernization of military equipment. Based on the resource constraint, this article aims at the resource "bottlenecks" such as the unreasonable structure of energy consumption, high dependence of traditional fossil energy, large resource dependent degree on foreign countries, low resource utilization efficiency, serious environmental pollution, starts from every stage of the whole life cycle of equipment, regards idea of sustainable development as guidelines, proposes strategic actions including strengthening the resource design, adjusting the energy consumption structure, strengthening resources substitute, improving the recycling system and so on, in order to break through resource constraint and realize the strategic measures of equipment sustainable development, in the hope of having some realistic significance in equipment construction and development under the new situation.

Abstract: With the development of the equipment resources conservation in PLA, the equipment resource-ability is proposed as a basic property of the equipment. The reaction of the equipment are available to promote resource saving and environment-friendly capabilities. With the deepening of the study, how to transform the equipment resource-ability from theory to practice and how to measure the existing equipment’s equipment resource-ability become the urgent problems. As the important component of the equipment resource theory system, the evaluation of equipment resources can response the level of equipment resource-ability correctly and objectively and also can offer the instruction for the equipment research department on comprehension and improvement of equipment resource-ability. Setting out from the relevant concepts of equipment resource-ability, this thesis proposes the basic principle of evaluation of equipment resource-ability, which is the whole life cycle principle, typical and representative principle as well as the oriented principle. Meanwhile, through the analysis on each stage of the whole life cycle of equipment, this thesis elects some factors that has a greater impact on equipment resource-ability, namely equipping materials selected, function structure and disposal of pollutant. The impacts of the three factors mentioned above on the equipment resource-ability mainly reflect in the sustainable ability of equipment consuming resource, resource utilization efficiency and environmental impact. Therefore, this article will regard the sustainable ability of equipment consuming resource, resource utilization efficiency, environmental impacts as the principal parts of evaluation of equipment resource-ability., At the same time, the index such as the using proportion of scarce materials, the comprehensive energy consumption, the pollutant of liquid, emission, gas at unit time and the degree of human health damage will be as a specific index of evaluation of equipment resource-ability in the thesis.
