武夷山自然保护区生物资源丰富的原因探讨

武夷山自然保护区丰富的生物资源,早已为国内外生物学者所瞩目。近两年来,我们的考察成果作了进一步的证实。武夷山自然保护区生物资源之所以丰富,显然是与保护区的自然环境、古地理演变有着密切的关系,也与历史上人为干扰少分不开。本文主要从这几方面加以论述。一、复杂的自然地理环境武夷山自然保护区的自然地理环境是十分复杂的,其中对生物影响最大的是地貌和气候两个因素。     

武夷山不同地区蝇类分布调查

作者于1990—2001年先后在武夷山自然保护区、武夷宫和武夷市郊区等地开展蝇类调查,共发现武夷山地区蝇类6科54属121种。其中自然保护区63种,武夷宫101种,武夷市郊区57种。

通过检查2002年至2009年期间采自福建武夷山自然保护区的天蛾科昆虫标本共2000多号,鉴定出保护区内的天蛾科昆虫分别隶属于5亚科、32属、72种和亚种,其中9个种和亚种为福建省首次报道.本文分别编制了武夷山自然保护区天蛾科昆虫的分属种检索表和福建新纪录种名录,为进一步研究此类昆虫提供基础资料.     

武夷山自然保护区生态旅游环境承载力研究

根据生态旅游环境承载力的定义、内涵以及生态旅游环境承载力的特征构成,对武夷山自然保护区生态旅游环境承载力进行测定,结果表明：武夷山自然保护区生态旅游环境承载力的限制因子是其资源空间因子,三港-黄岗山精华旅游线对保护区的生态环境空间承载力具有明显的卡口作用,属于不完全游道;三港-黄岗山一线的日卡口承载力为1 450人次/天,年卡口承载力为359 020人次/年。这一环境承载力可作为武夷山自然保护区生态旅游活动的环境承载量限制量。     

“点水翁”话说武夷

武夷山自然保护区自建立至今已20年,有一位与武夷山结下了不解情缘的老科学家,他就是福建农业大学植保系教授、博士生导师——赵修复.我曾是他的学生,现在在福建省电视台社教节目中心《绿色家园》任编辑,正在筹备拍摄武夷山自然保护区电视系列专题片,接受《中国生物圈保护区》杂志的委托,在拍片过程中专门拜访了赵老师.

建立武夷山自然保护区的一些回忆

今年是武夷山自然保护区建立20周年.在纪念这个喜庆的日子里,我对武夷山自然保护区建立20周年来所做的工作和所取得的成绩表示衷心的祝贺.许多人都说武夷山自然保护区的建立是赵老倡议的,我觉得这个倡议同样也包含着许多人的共同心愿.现在我把倡议的经过作一些回忆.1978年,我看到当时崇安县(现为武夷山市)委会对台工作办公室一封信,知道崇安县对台

武夷山自然保护区藻类植物资源考察初报

武夷山自然保护区的生物资源极其丰富,种类繁多,享有生物模式标本采集胜地之盛誉。然而,对于武夷山的微观世界之一——藻类植物却没有受到人们的重视。据了解,国内外科学工作者从未对该地区的藻类资源进行过采集、调查或研究。为此,我们于1979年夏,应省科委、科协的邀请,参加武夷山自然保护区综合科学考察队,对保护区内的藻类植物进行初步的采集观察,借以了解藻类植物的种类、数量和习性,为今后继续深入调查研究和利用该地     

武夷山自然保护区苔藓生态群落初步调查

作者等在武夷山自然保护区对苔藓植物进行了多年的考察,到现在止,已知有355种,现在按照陈邦杰教授(1959)对苔藓植物群落类型的划分,把武夷山自然保护区的苔藓植物生态群落,分为5个生态类型,即:水生苔藓群落(Bryo-Hydrophytia)、土生苔藓群落(Bryo-Geophytia)、石生苔藓群落(Bryo-Petropytia)、树生苔藓群落(Bryo-Epixy-loplophytia)和叶附生苔藓群落(Bryo-Epiphyllitia),讨论如下。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that
