VMS在旅游公路景观影响评价中的应用

应用美国林务局的“风景资源管理系统”（VMS）对贾登峪-禾木乡旅游公路进行了景观影响评价。结果表明,从处于低位的观察点来看,山体的不同垂直位置承受的工程活动强度不同。山体的上半部能承受一定强度的工程活动,受公路建设的影响轻微;但山体的中下部能承受的工程活动有限,受公路建设的影响较大。具体分析表明,公路设计的老路方案和四级路方案对泰加林山体的景观影响程度基本相同。

Assessing the influence of urban geometry on noise propagation by using the sky view factor

The impact of traffic noise can be prevented by suitable planning measures. This study analyses the relationship between urban geometry and traffic noise, recognizing that the arrangement of buildings and streets greatly influences urban noise. The study was carried out in Braga, a medium-sized Portuguese city, by selecting locations with different urban geometries. At each site, the equivalent continuous sound level was measured. Furthermore, the urban geometry was evaluated by using the sky view factor, a parameter which shows the degree of sky obstructed by buildings. Results show an inverse proportionality between noise and the sky view factor. The highest noise levels were found in areas with a low sky view factor. The results also indicate that the sky view factor is a parameter which can potentially be used in research on urban noise.     

Green-Tinted Glasses: How Do Pro-Environmental Citizens Conceptualize Environmental Sustainability?

Recent research has shown that many Australians see pro-environmental behaviour as desirable and identify as being green. However when compared to other countries, Australians score poorly on pro-environmental behaviour measures, engaging mostly in tokenistic pro-environmental actions, and demonstrate low levels of concern for the environment. In this article, we examine this tension through exploring the meaning of the term sustainability to Australian participants who self-identify as pro-environmental. Twenty-six interviews were conducted and analysed using a causal layered analysis. Through the examination of participants’ environmental discourse and practices, some of the deeper socio-psychological processes influencing pro-environmental behaviour are revealed. While participants aspired to be green, their actions were bound by cultural traditions and world views that perpetuate environmental degradation. Participants struggled to define the term sustainability and held self-enhancing motives for adopting what they identify as a pro-environmental identity. These findings highlight the influence of collective cultural constructs in shaping how pro-environmental behaviours are understood and enacted.     

论污染防控与生态保育

近年来,不仅是生态保育,污染防控也越来越呈现出区域性乃至整体性,这是由环境自身运动规律决定的。污染防控和生态保育必须重宏观、重预防、重效率。环境污染加剧生态破坏,使脆弱的生态环境雪上加霜,也使生态问题更加复杂化,但环境污染不是生态环境问题的全部。生态问题必须用生态的办法来解决。违反自然规律的行为必须禁止,让不堪重负的生态系统休养生息。生态保育不仅是解决生态问题的基本出路,也是从深层次上解决污染问题的基本出路。生态保育是生态文明建设的一个重要组成部分。不论是污染防控,还是生态保育,都必须同时遵循自然规律和社会主义市场经济规律,激发市场主体保护环境的内生动因,方能可持续发展。     

The ratio of clay content to total organic carbon content is a useful parameter to predict adsorption of the herbicide butachlor in soils

Thirteen soils collected from 11 provinces in eastern China were used to investigate the butachlor adsorption. The results indicated that the total organic carbon (TOC) content, clay content, amorphous Fe2O3 content, silt content, CEC, and pH had a combined effect on the butachlor sorption on soil. Combination of the data obtained from the 13 soils in the present study with other 23 soil samples reported by other researchers in the literature showed that Koc would be a poor predictive parameter for butachlor adsorption on soils with TOC content higher than 4.0% and lower than 0.2%. The soils with the ratio of clay content to TOC content (RCO) values less than 60 adsorbed butachlor mainly by the partition into soil organic matter matrix. The soils with RCO values higher than 60 apparently adsorbed butachlor by the combination of the partition into soil organic matter matrix and adsorption on clay surface.
