Abstract: The paper which based on the idea of “low carbon economy” scanned the wood carbon storage function and analyzed the wood carbon storage from the present research situation of home and abroad. And it put forward the research content and specific research methods of the wood carbon storage. Finally it summarized the expected achievement and development trend of studying the wood carbon storage under the construction of low carbon economy. The research will have the practical directive function about realizing the energy saving and emission reduction of carbon dioxide, transforming the mode of economic development and improving the wood’s carbon storage.

Abstract: From blood faan civilization. Marriage ceremony, as a traditional conversion, has been drifting away from its original purposes. It becomes a typical consumemily marriage to the modern monogamy, human being has been experiencing several types or forms of marriage and marriage itself become one of the signs for humr behavior and also starting to lead the fashion trend within communities. Modern wedding celebration, especially the environment decoration design, also start to emphasis on the aspect such as significance, mood, aesthetic feeling, class, taste, romance and atmosphere.

Abstract: This paper describes the processes of integrated bionic honeycomb plates: A beetle forewing has integrated honeycomb structure, which consists of trabecula-honeycomb and a frame. It is expected to lead to a molding method enabling the creation of an integrated trabecula-honeycomb structure; we have developed an integrated honeycomb plate.

Abstract: To establish complete stress-strain curve equations for confined concrete in cross-shaped columns, we designed 7 test specimens corresponding to the usable eigenvalue range of stirrup of the cross-shaped columns. We obtained the test results of the reinforced concrete cross-shaped columns through axial compression test, got the system parameters of a stress-strain model through statistical analysis of the test data, and then established stress-strain curves for confined concrete in the cross-shaped columns. This model reflects the variation rule of the stress-strain curve of confined concrete in cross-shaped columns. Compared with the stress-strain model for confined concrete in square columns, the confined concrete in cross-shaped columns has smaller peak stress, larger peak strain, and relatively steeper descending part of curve. The research results provide theorotical basis for nonlinear analysis of cross-shaped columns.

Abstract: Based on two different methods, the ecological risk of heavy metals in soils of Beijing was assessed. With the assess method of PaPant ecological risk index, the Rapant ecological risk index of center region is 1.365, which indicates a medium ecological risk, while the other districts of Beijing are in low ecological risk level and the main influential factor is Hg. Based on the assess result by the method of Hakanson potential ecological risk index, The highest value of RI is 141.95, which is still in the low ecological risk level but also close to the lower limit of medium level; the main influential factors is Hg and Cd. Therefore, to focus on the monitoring and management of Cd and Hg in center region is necessary in Beijing.

Abstract: Three kinds of complex chemical activators were prepared and then introduced into calcined coal gangue cement. Physical and mechanical properties such as mortar fluidity and mortar strength and shrinkage were tested. The results can show that: excitation effects of multiple complex chemical activators may obvious, where with 8% of J1, 50% of cement replaced with activated coal gangue, compressive strength of the system at ages of 28 days can reach 40.7MPa. Compared with coal gangue cement system without exciting agent, in calcined coal gangue cement system with complex activators early shrinkage increased obviously and later shrinkage may be equivalent to that of pure cement.

Abstract: People increase in demand of the cemetery architecture to result in serious ecological problems, such as the land utilized greatly and environment polluted etc. because of the number of the world population has grown rapidly and an aging population with developing rapidly urbanization. The paper interprets design ideas of the cemetery architecture and all kinds of ecological transformation types at present, thereby realizing sustainable development city.

Abstract: Green medical environment calls for fine quality of environment both in outside and inside. The article explains the function of natural ecological green plants in the improvement of medical environment quality from different angles, sums up the principles of green space design in various districts，and points out to lay stress on the characteristic of environment and to create green hospital which combine with the nature will be the direction of healthcare buildings design in the 21st century.

Abstract: architecture, scene type, exchange type, cooperation type, defense type Abstract. Architecture is an ancient subject discipline. Over the years, its unique teaching methods have formed. In this article, based on the analysis of present teaching problems, the author proposed teaching methods of “scene type”, “exchange type”, “cooperation type” and “defense type”. Through the teaching practice, the author research and try the new teaching operation modes of design courses, to improve the level of teaching and learning in architecture.

Abstract: The one of the ancient building’s important values is the historical and cultural information, in some sense, the protection of ancient building is to protect this information. Take advantage of the technology of information, we collect the information of ancient building, and in the way of database to save the information, achieve the protection of ancient building’s information. Relative to the protection of the actual ancient building, the protection of information could rapid to achieve the goal and reduce the cost. Unexpected disasters often cause serious damage to ancient buildings, only the protection of information could keep the information of ancient building for long time. The information of ancient building including information of the graph and attributes, there are the same properties with the geographical information. Take advantage of the technology of GIS, create 3D graph of the ancient building’s unity, component and structure, and collect the information of material, paint, dimension for each component, establish attribute table, connect the graph with attributes, achieve the integrative management of the ancient building’s graph and attributes. The database which is formed by the protection of ancient building’s information, it is the base which produced 3d virtual and digital ancient building through computer technology, meanwhile, digital information for the purpose of research and protection of the actual ancient building has important reference value.
