中英植物词汇与文化浅析

语言是文化的一个重要部分,没有语言作为工具,人们将无法交流和相互理解;与此相对应,文化也通过语言来体现,各种不同的语言体现着不同的文化。透过中英植物类词语,可看到不同的文化对语言的影响及其在语言中的体现,同时也可以看到不同的语言对其文化的能动作用。     

Uncertainty in Comparative Risk Analysis for Threatened Australian Plant Species

Australian state and federal agencies use a broad range of methods for setting conservation priorities for species at risk. Some of these are based on rule sets developed by the International Union for the Conservation of Nature, while others use point scoring protocols to assess threat. All of them ignore uncertainty in the data. In this study, we assessed the conservation status of 29 threatened vascular plants from Tasmania and New South Wales using a variety of methods including point scoring and rule-based approaches. In addition, several methods for dealing with uncertainty in the data were applied to each of the priority-setting schemes. The results indicate that the choice of a protocol for setting priorities and the choice of the way in which uncertainty is treated may make important differences to the resulting assessments of risk. The choice among methods needs to be rationalized within the management context in which it is to be applied. These methods are not a substitute for more formal risk assessment.

直与天地万物上下同流——论中国古典哲学背景下的生命意蕴

中国古典哲学把"天人合一"作为生命的最高境界,并在对生存意义的不断扣问中追究实现生命极境的路径。以海德格尔为代表的西方人本主义思想也在追索同样的问题。这些关于生命整体和谐性与自由超越性的探索,对人类的生存与未来发展无疑有着深远的意义。     

道德义务的现代诠释

过去人们一直将道德义务限于人类社会领域,但是当大量的环境问题出现的时候,迫使人们不得不重新对道德义务进行思考.在当前的时代背景下,道德义务不仅包含人类对自身的道德义务,还应该包含人类对自然的道德义务,以及两者之间的关系.     

黄河三角洲C3植物δ13C对盐度变化的响应

通过对黄河三角洲地区C3植物稳定碳同位素组成以及土壤盐分的调查,初步探讨了C3植物δ13C与盐度的关系,揭示了环境因素对植物δ13C的影响.结果显示:黄河三角洲地区C3植物δ13C与盐度之间呈线性正相关关系(P<0.005),且随着盐度的增加,C3植物平均δ13C值呈偏正的趋势(P<0.005),土壤盐分是植物δ13C值的重要影响因素,单个植物种δ13C随盐度上升表现为增加和变化不明显2种模式,这与植物本身的遗传特性、耐盐性强弱等有关.     

Diversity of vascular plants growing on walls of a Brazilian city

City walls are very specialized environments, conditioned by human activities. There is little information about plants that invade human-made habitats, and no study done in Brazil with plants growing up on walls. The aim of the present study was to survey the wall vascular flora of a Brazilian city, comparing the diversity found in its downtown and neighborhoods. Fieldwork was done in Jundiaí, São Paulo State, where data was collected in downtown and in five neighborhoods. In each place, three transects of 1 km were established and every plant individual was registered. Twenty-eight species were identified, all of them on the downtown transect and most also on the neighborhood transects. Five species were the most frequent, although none were dominant. The diversity indicies of the six transects were not significantly different, with an overall diversity of H′ = 2.93.

论花卉的旅游审美意义

花卉是最具吸引力的旅游景观之一 ,具有“色、香、姿、韵”四个方面的旅游审美意义。花卉的色彩给人的美感最直接、最强烈 ,不同花色具有不同的感情象征意义。花卉的香味包括“香”与“味”两个方面 ,不同的香型具有不同的美感类型。花卉的姿态千变万化 ,因与季节无关而具有持久之美。花卉的风韵美是花卉各种自然属性美的凝聚和升华 ,是一种自然意态之美 ,它比花卉纯自然的美更具美学意义。由于作为欣赏对象的花卉是一种具有生命的自然之物 ,因而 ,花卉欣赏是一项特殊的审美认识活动 ,除了受审美主体的知识水平、文化素养、情绪条件等影响之外 ,还受自然条件和天时景象的影响。
