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.

植物对甲醛吸收的气相色谱研究

为了比较几种常见居室观赏性植物对室内甲醛的吸收效果,本文采用定时抽取放有植物的密闭箱内气体,以蒸馏水吸收,直接进样气相色谱法测定甲醛浓度．结果显示甲醛的浓度在0．2～1．0μg／mL范围内,线性关系良好,回归方程Y=0．14261x-0．14711,（r=0．99657,n=6）,检测限为0．053μg／mL;样品分析的精密度试验,相对标准偏差为1．27％．可见,以蒸馏水直接进样气相色谱的方法测定植物对甲醛吸收准确、简便．植物对甲醛吸收能力为：芦荟〉虎尾兰〉仙人掌〉玉树．     

校园多功能教学基地“中华名特优植物园”的建设

利用农科高校的校内教学用地,精心设计创建了具有六大功能的"中华名特优植物园"。此园占地7万多平方米,模拟中国及其34个省(市、区)的行政地图,按实际面积的比例划分建设成34个园,每个园分别种植该省(市、区)名特优植物并附有学名和功能的说明牌。此园具有如下功能:(1)教学功能。作为11个本科专业"植物学"课程的教学基地,平均每学期有1174位学生在此实习32学时。(2)科研功能。该园是全国主要名特优植物的种质资源库。(3)科普功能。可学习到我国大量植物精华及其科普知识与前沿成果。(4)运动功能。"国界线"宽1.8米,"省界线"宽1.2米,总长2136米。34个园均设立打卡器,上体育课时运动员在入口处刷卡后开始计时,跑遍"神州大地",即在34个园都刷了卡且所用时间最短的为优胜者。(5)社会功能。台湾高校师生来此园学习祖国大陆各省的名特优植物,增进了他们对地大物博的中华大地的了解,增强了他们的中华民族意识,该园也是学校对外交流宣传的特色平台,来宾在工作地的省园植树强化了他们对学校的深刻印象和美好记忆。(6)创新教育功能。该园有助于增强学生的创新意识,启发学生的创新思维,激发学生的创新灵感。

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.
