Abstract: In sports ecological perspective, adopting the literature material method, expert interview and logical induction, for large sports venues green construction and current situation of the development and utilization of system analysis and research, on this basis building a large sports venues and green sustainable development mode. The results of the study conclude that the large size stadium design, construction, operation as an ecological system was studied. In every link of fusion, through green, save and sustainable development thought. Using this model will be good for large sports venues construction and sustainable utilization.

Abstract: According to the energy-consuming characteristics of buildings in hot summer and warm winter area, a direct-expansion solar-ground source heat pump system is put forward. This system runs the direct-expansion solar heat pump system in summer and direct-expansion solar-ground source heat pump system in transition season and winter to produce hot water. The article analyses the thermal contribution rates of double-heat sources of the system under various working conditions in different seasons. Results indicate that the total area of solar evaporators matches the power of units and the matching value is 2.18m²/kW. When the average daily total solar radiation is 15.8MJ/m² in summer, 11.2MJ/m² in transition season and 11.2MJ/m² in winter, the unit area heat transfer are respectively about 1.48kW/m², 1.1kW/ m² and 0.43kW/m². The annual solar thermal contribution rate is 46.4% and the annual soil thermal contribution rate is 32%, which can reduce 57.96% quantity of heat absorbing from the soil.

Abstract: Most of metallurgy industry enterprises in our country were built early and the architectures of which were old while environment colors miscellaneous. With the rapid development of economy and improvement of aesthetic standard, the art and aesthetic of industry architecture environment was paid the important attention. Color plays a very important role in the environmental cognition aspects. It can not only facilitate people to cognitive surrounding responsible and dangerous working environment, but also to allow workers to improve work efficiency and improve the living comfort level. A good relationship with the color and the industry environment is important to our future industrial landscape design and industrial architecture design. And we should present the building colors with new ways so as to create Chinese industrial culture with Chinese characteristics. Based on the industry architecture environment, this article expounds the importance, emotional and functional of color design, and deeply analysis the effect and influence factors of color design in industry landscape architecture environment, and also brought the requirement to color design.

Abstract: Computer aided design is an effective means of wind environment assessment and prediction under complex layout, In this paper, the relationships of contact and containment among wind environment was studied by coupled simulation and analysis of wind environment around residential quarter in hot summer and cold winter area, and analyzed how to fix the layout of indoor and outdoor by simulation software during the operation, and make them reach the requirement of Evaluation standard for green building, at the same time make the ecological effects of the buildings complex to maximize.

Abstract: Sustainable ecosystem organizes itself to fit in the environment by assimilating nature energy with little technology help, water ecosystem in the Mengqing park is such a nature system which integrate both biodiversity and economic values together. The work of designing of water ecosystem in Mengqing park is conceptually based on the theory of ecological engineering, presents the natural principles of ecosystem design, discusses seven major ecological indicators including hydrology, soil substrate, oxygen, vegetation, biotical, chemical, and bank construction.

Abstract: The natural smoke exhaust is as acknowledged as a common smoke control manner, with simple form and does not require additional energy support either with the complex exhaust facilities. In this paper, the field model FDS (Fire Dynamic Simulator) with a combination of zone model CFAST (Consolidate Fire and Smoke Transport) were used to simulate the natural smoke exhaust in a straight corridor of a high-rise hotel, for the propose of evaluate fire safety of smoke exhaust. The major discussing factors are the outdoor wind direction, wind speed, et al. Height of smoke layer interface was used to evaluate the effect of smoke exhaust. The conclusions were obtained as followed. As the outdoor wind speed increases, the outdoor windows in the windward effects worse in natural smoke exhaust, but the window in the leeward side effects better.

Abstract: Based on the landscape urbanism theory and the shortcomings of the application ,this article expounds the necessity of introducing the landscape design course.Combing with the real classroom teaching expericence, it discusses the theory of landscape urbanism and the application in the campus landscape Architecture.

Abstract: For the justice between generations, the concept of sustainable development has become the tendency of national development in 21 century. The guideline and indicator system for sustainable development were established already in Taiwan. The issues of eco-city, health-city or sustainable city have discussed in several cities these years. However, the key point of sustainable development is to reduce consumption of resources. A recycling-based society is the ultimate aim. In this research, issue-based indicator framework was adopted to construct an indicator system focused on the assessment of recycling representation in a city. With the considerations of resource input and recycling, the performance of resources utilization can be realized. Top five cities in Taiwan were selected as the case study. Other assessment results from existed indicator systems were compared with the proposed indicator system for distinguished the difference between various systems.

Abstract: In this study, an isothermal microcalorimetry was used to demonstrate the long-term impact of dimethyl phthalate (DMP), dipropyl phthalate (DBP), dioctyl phthalate (DOP) and dicyclohexyl phthalate (DEHP) on the soil microbial activity. Generally, the toxicity order of four phthalate esters (PAEs) is DBP>DMP>DOP>DEHP. The PAEs show inhibitory effect when the soil was exposed to PAEs for 10 days and the PAEs will have a small stimulate effect after 30 days, and then the PAEs inhibit the soil microorganisms again. The effect of PAEs on soil microbial activity is almost the same as those on urease activity.

Abstract: The objective of the article is to construct a model to help Chinese government with water policymaking. This paper will take the policy of water price ladder model as an example,respectively pricing for municipal water and industrial water. The strategy of waters price ladder can promote the conservation of water resources.
