基于景观生态学的旅游公路路域景观 现状与生态敏感性研究

选取青海扎碾旅游公路为研究对象,充分考虑其路域景观环境的特点,从景观生态学的角度,基于遥感影像和ArcGIS软件,在景观格局空间分析的基础上,分别从可视视域、丹霞地貌面积比、喀斯特地貌面积比、草地面积比、林地面积比、农田面积比、居民点密度和景观综合指数几个方面对路域景观进行分析与评价,从而得出扎碾旅游公路沿线路域景观特点。研究成果可为旅游公路的后续景观设计与营造、生态恢复等方面提供数据参考。     

塔里木盆地奥陶系生物礁的发现及其意义

通过对塔里木盆地野外地质露头的考察和岩心的观察以及地震剖面的解释 ,在奥陶系发现了大量的生物礁。生物礁的分布地区和层位存在着规律性 ,从层位上来看 ,生物礁主要分布在中、上奥陶统 ;从地区来看 ,主要分布在塔中、轮南、巴楚、阿尔金断隆和库鲁克塔格地区。造礁生物主要有层孔虫、苔藓虫、珊瑚、蓝绿藻、管孔藻、托盘类、海绵 ,附礁生物主要有角石、腹足、棘皮、介形虫、瓣鳃、腕足、海百合、藻类、三叶虫、头足类 ,不同地区造礁生物和附礁生物组合是有差异的。生物礁发育的环境是台地边缘和台地内部相对高的地方。生物礁的发现无论在实践中还是在理论上都具有很重要的意义。图 2表 1参 4     

Comparative trophic ecology of nearshore juvenile salmonids in Lake Ontario

The trophic ecology of juvenile salmonids in nearshore Lake Ontario is not well understood. We used stomach content and stable isotope diet and niche metrics, as well as condition metrics to understand the trophic ecology of juvenile Atlantic salmon (Salmo salar), brown trout (Salmo trutta), Chinook salmon (Oncorhynchus tshawytscha), coho salmon (Oncorhynchus kisutch), rainbow trout (Oncorhynchus mykiss), and lake trout (Salvelinus namaycush). Salmonids had comparable length-weight slopes and stomach mass, and allometric patterns existed between fork-length and both relative stomach content mass and energy density for all species. Interspecific differences existed with respect to diet, and the magnitude of difference generally increased with increasing body size. Small sized salmonid (fork length < 100 mm) diets mainly consisted of Diptera (% volume = 66 – 100; prey isotope %: 11.7 – 78.4), while large sized salmonids (fork length 200 – 300 mm) consumed fish (% volume = 20–100; prey isotope % = 21.5 – 42.7). Salmonids exhibited high interspecific niche overlap, with lake trout (SEA_B = 22.9 ‰²) and brown trout (18.6 ‰²) having the largest isotopic niche size, and Atlantic salmon having the smallest (2.7 ‰²). Our study addressed a knowledge gap in trophic ecology between mostly stream-dwelling juvenile and open lake adult salmonid life stages, revealing differences in diet but comparable condition metrics which suggests different strategies to optimise performance in the nearshore environment.     

作用逻辑与实践路径：新兴空间媒介影响下的建筑实践图景与场域生态特征（2010年至今）

新兴空间媒介作为促发性技术因素与新型社会结构性力量,浸润至建筑与社会其他领域关系的长期结构转型中,激发出“人——空间——社会”之间崭新的关系互动与作用方式,广泛地改变了建筑创作语境,并深刻反作用于建筑创作与空间内涵认知,在当下形成了诸多值得关注的建筑实践新趋向。文章以媒介相关理论为指引,聚焦新兴空间媒介在时空感知、制度性运作与社会建构等层级所触发的城市建筑实践中的新图景与新特征,系统性考察其对于城市建筑实践的作用。

Effectiveness of daylighting design and occupant visual satisfaction in a LEED Gold laboratory building

Using daylight as primary light source has been widely recognized as an important strategy to reduce building energy demand and enhance indoor environment quality. However, to design and operate a building to make full use of daylight, which is a dynamic light source, to meet diverse occupant needs remains a challenge. This paper reports a post-occupancy study of the visual environment in a laboratory building on a university campus, and puts a spotlight on the building occupants as it examines the effectiveness of the daylighting design and systems integration in creating a visual environment to support occupant comfort and satisfaction while reducing artificial lighting demand. Results show generally high satisfaction with daylit work environment and positive effect of the horizontal shading strategy. Issues about the integration between daylighting and electric lighting systems and level of occupant control are identified and discussed for improving the effectiveness of daylighting and enhancing the quality of the visual environment in the building of study. A multiple-tool methodology is developed and tested, which included occupant surveys, interviews, illuminance measurements, continuous data loggers, fisheye-lens camera and glare-identifying software, and documentation of spatial settings, systems features, and user behavior.     

《人文主义时期的建筑法则》与现代主义

艺术史学家威特克沃出版于1949年的文艺复兴研究专著《人文主义时期的建筑法则》是一本对当代建筑批评与实践影响重大的著作。本文将分析威特克沃在该书中所发展出来的建筑研究方法．探讨其如何被吸纳进当代建筑批评及实践．如何奠定了当代建筑形式理论的基础，以及如何被其后辈所发展．而成为对20世纪30年代现代主义的反思和修正。     

An animal-as-client (AAC) theory for zoo exhibit design

The enthusiasm for the use of so-called native plants and the rejection of so-called exotic plants in 20th-century garden and landscape design is explored. The underlying ideas and ideology are discussed using examples in Germany, particularly from the time of National Socialism, and the United States.
