Abstract: This essay is aimed at stressing the importance of the cultural value importance of the outdoor environment of university campus, and reflecting the common understanding of the university students on the value of the outdoor environment of university campus. University campus environment characteristics of culture determine the overall cohesion of the campus and students on the campus of the identity and ownership. Therefore, today's campus planning and design should enhance the campus culture of outdoor space environment, in order to cultivate, education, teachers and students.

Abstract: Museum has its particularity in public buildings and high research value for its thermal and humidity environment and building energy efficiency status. According to a investigation of air-conditioning systems and a test of indoor heat and humidity parameters in summer and winter for a museum in Shenyang, this article analysis its thermal environment and air-conditioning energy consumption status, draw the winter and summer indoor temperature and humidity and air-conditioning energy consumption chart, research the indoor temperature change rules and the energy consumption status of air-conditioning system in winter and summer. The results show that as air-conditioning energy consumption accounted for the main body of museum’s total building energy consumption, more energy-efficient technologies can be used to reduce the energy consumption of air-conditioning systems. And how to control the thermal environment of different types of collections in this museum, and take a consideration of energy saving, are focues of future research.

Abstract: It is difficult for Johnson and Ettinger model to predict the intrusion rate of organic vapor from double soil systems into buildings. Here new analytical equations were derived, which were different from those of Johnson and Ettinger model. These new equations were verified by Eclipse 2003a, and the results indicated that new equations were valid.

Abstract: The plan and architectural design of the campus is one part of green ecological building, which is the ingredient of architectural theory of sustainable development. Beginning with the plan of ecological campus, this paper analyzes design technique of ecological building in different areas. According to the characteristics and priorities of different areas, the different models of design are built and the different means of energy conservation and emission reduction are adopted in this paper. So the aim to save energy resources and utilize resource scientifically and efficiently will be realized. This paper will be a salutary lesson to create humanistic, ecological and intellective campus landscape with abundant connotations.

Abstract: Every industry keen to maximize their company profit by fulfils the customer’s satisfaction by perform a very good project deliverable. However, very limited researches on uncertainty in environmental issues (EI) probably could turn as a biggest problem for company, especially in late delivery of project completion for construction industry (CI). Uncertainty factors could be mapped by many causes and affects which known or unknown, statically to totally ignorance. Previously, most of research on uncertainty have been model their factors of uncertainties but pay no attention to the EI, whereas in the real cases all the factors must controlled and manageable even it is in-deterministic or non-realistic. Therefore, the modelling of uncertainty factors in EI on late delivery for CI is very important to studied, and it will be considered to be used as the guidance for decision makers when they are facing of the problems that related to uncertainties. This paper will purpose the conceptual model on progress to the modelling of uncertainty factors in EI on late delivery for CI. The uncertainty of environmental can split into two categories; acts of God and acts of humans.

Abstract: Based on test data of field soil water infiltration, Back-propagation (BP) model of predicting Kostiakov infiltration model parameters was established after analyzing the primary influence factors of water infiltration model parameters. The results indicate that BP model can reflect the non-linear relationship between the model parameters and the physical parameters of the soil; BP model is high accuracy for prediction soil infiltration model parameters. It can be referred as a new method to predict soil infiltration process using soil physical parameters.

Abstract: The limestone soils and its source rock samples had been collected from Suzhou area for the testing about major and trace elements. The concentration value have been compared with the background and the migration coefficient(K) of element form source rock to soil have been calculated, the result showed: the elements Ca and Th are enrichment, the Al is loss seriously, the Ti, V, Cr, Mn, Zn, Rb, Sr., Zr, and Pb are basic fairly with the background value; the K, Cu, Fe and As are slightly higher than the soil background values; The elements Si, Ti, Mn, Zr, Pb and Th have high K in subsoil layer; the element Fe, Cr, As and Rb have the least K in subsoil layer; the element Al, V, Cu and Zn can be showed disorder with the more high migration coefficient in topsoil.

Abstract: Tianluoshan relic sites is a typical earthen sites located at moisture circumstances. The potential application of silicone for strengthening Tianluoshan relic soils were evaluated by a series of unconfined compression tests. The main considered influence factors includue: curing condition, curing time, and variation of water content. The results show that the compressive strength of Tianluoshan relic soils solidified by silicon increase with curing time, and silicon can effectively improve the strength of Tianluoshan relic soils under constant temperature & moisture condition.

Abstract: Soil water content is considered to be one of the most important factors affecting crop productivity. In this study, the different management practices were investigated in the black soil of Northeast China to evaluate the efficacy of practices on soil water content. The results showed that the application of organic matter, large-scale machine and residues retention have positive effects on soil water content. Saturated water content (SWC), field water-holding capacity (WHC), and available water content (AWC) were strongly correlated with soil bulk density and soil organic matter. Our results suggested that proper management systems could improve soil water use efficiency in black soil region of Northeast China.

Abstract: 6 congeners of phthalate esters (PAEs) were analyzed in soils with various land use types from the area around Hongze Lake, the fourth largest freshwater lake in China. The total concentrations of 6 congeners (Σ6PAEs ) were 5.070-2.067, 0.723-2.050, 0.331-1.645, 0.002-0.173 mg kg-1 in surface soil from plastic film greenhouse (PG), conventional vegetable fields (CV), plastic film greenhouse-rice rotated fields (PR), and uncultured land (UL), respectively. DnBP and DEHP were dominant species in PAEs averagely accounted for 46.4% and 47.0% of the Σ6PAEs concentrations in all surface soils. And congener percent composition of PAEs in surface soils from uncultured land was considerably different from cultured soils. Vertical distribution of PAEs in soil profile was influenced by land use type, congener species, and the content of congener in surface soil, etc. However, the amounts of PAEs in surface soil accounted more than 58.5% of total amounts in soils. In addition, no significant relationship was observed between total organic C or pH and the concentrations of PAEs in surface soil. The contents of PAEs in soils from the area around Hongze Lake were related with land use types, especially with the use of plastic film. And the general contamination level in soil was comparable or lower than those present in other areas. According to our knowledge, this is the first study to examine the present status of PAEs in soils from the area around Hongze Lake
