辨析生态旅游内涵

生态旅游是一种新兴的旅游产品,国内外学者对生态旅游概念有不同的阐述,剖析各种界定,指出生态旅游的四个标准:是一种旅游方式;以自然为基础;以可持续发展为原则;以学习和教育为核心内容。在此基础上,讨论了生态旅游与绿色旅游、自然旅游、探险旅游和可持续发展旅游的区别和联系,揭示出生态旅游的本质内涵。     

吉林省生态旅游产品开发的探讨与研究

生态旅游是当今旅游业中增长最快的旅游形式,它是以人类对旅游与环境相互关系的反思为基础的,是生态环境伦理及可持续发展思想在旅游中的体现。生态旅游是通过旅游者在相对原生的自然区域（包括人文）进行的欣赏、探究、享受、保护自然的旅游活动,为保护区筹集资金,为当地社区提供就业和参与决策的机会,以实现旅游目的地的可持续发展。本文结合吉林省的生态旅游资源特点,对生态旅游产品的开发进行了研究和探讨。     

从旅游市场现状谈生态旅游及其可持续发展

从旅游的本源含义看,旅游是一种异地性休闲体验.从生态旅游的定义看,生态旅游是旅游大市场中的一种新兴旅游产品,也是依托并认知自然生态环境的旅游可持续发展的最佳模式.从旅游需求层次看,生态旅游是比传统大众旅游更高行为层次的旅游.结合生态旅游的理论和国内旅游市场表现,生态旅游的可持续主要取决于三个方面的因素:生态旅游资源的可持续供给能力;生态旅游的市场需求潜量;旅游服务商的生态旅游服务.

广西宜州市开发生态旅游的资源优势和对策探讨

生态旅游被认为是实现旅游业可持续发展的必然选择,并将成为21世纪国际旅游的主流.刘三姐故乡宜州市生态旅游资源丰富,尤其是自然环境和原生态的民族文化优势突出,为开展生态旅游提供了良好的基础.该文针对宜州市旅游开发现状和资源优势,从提升经营者和开发者的文化素养、绿色营销策略以及区域旅游合作等方面提出了生态旅游的开发对策,以提升宜州市的旅游市场竞争力,保证旅游业的可持续发展.     

类生态旅游:一种注重自然保护的大众旅游

生态旅游不等于大众旅游,对生态旅游概念的扩展也不能违背其内涵要求,生态旅游的概念也不能照搬到大众旅游．类生态旅游概念吸收了生态旅游概念中自然保护和社区参与的思想,是一种具有创新意义的注重自然保护的大众旅游,其旅游目的地为非原生的自然生态系统,其自然保护主要依靠生态管理、生态技术和社区参与．     

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.     

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     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
