绿色经济理念的生态工业园区综合评价指标体系

基于绿色经济理论,提出生态工业园区绿色发展水平的内涵.从经济发展、生态环境保护、生态工业链建设及绿色管理4个方面综合考虑,建立了生态工业园区绿色发展综合评价指标体系.以福州经济技术开发区为例,利用熵权系数法客观地确定指标权重.利用综合指数法进行园区绿色发展水平综合评价,从中识别和分析开发区在“十一五”期间经济发展、环境保护、管理等方面存在的问题,并给予针对性建议.     

生态工业园区绿色发展水平趋势预测及驱动力研究

以绿色经济理论为基础,采用生态工业园区绿色发展水平评价指标体系,结合福州经济技术开发区"十一五"期间绿色发展水平的相关研究成果,并利用灰色系统理论对开发区"十二五"期间的绿色发展水平进行动态预测分析.结果表明:指标预测值与实际值整体变化趋势相似,"十二五"时期绿色发展水平总体上保持良好的发展态势.结合开发区发展实际情况,认为经济利益、资源与生态环境、企业共生水平建立、政策与制度的制定、科技创新是生态工业园区绿色发展的驱动力所在.     

生态工业园区建设瓶颈探讨

<正>从20世纪60年代美国经济学家鲍尔丁提出的"宇宙飞船理论"到如今的绿色生产、循环经济生态园区建设,可持续发展的研究和实践就在一直不断地深入进行着。随着社会对可持续发展的重视,在我国也开始建立以循环经济理论为依据的各种各样的生态工业园区。它以清洁生产为前提,从源头防治污染产生开始,在园区内部把不同的企业连接起来形成共享资源和互换产品的产业共生组合。彻底摈弃了经济发展与环境保护相互割裂、"先污染、后治理"的传统工业增长模式。

生态现代化

随着我国社会经济的快速发展,环境保护与经济发展的矛盾日益凸现,绿色家园、绿色地球的呼声越来越高,寻求一种环境与经济双赢的新模式成了现代人的共同愿望。以“生态现代化”为主题的《中国现代化报告2007》一经公布,立刻激起了社会各界广泛的关注。“生态现代化”逐渐走进人们的视线,成为世人关注的焦点,人们似乎从这种新模式中看到了巨大的魅力和潜力。其实,生态现代化建设在我国已有30多年的历史,但中国仍属于世界较低水平。生态现代化建设是整体现代化必不可少的组成部分和价值追求目标,是现代化发展到了一个高级阶段的体现和表证,是保证一个国家、一个区域、一个城市可持续发展的强大动力。以苏州、无锡、常州为代表的苏南地区是全国经济发展较快的区域之一。近年来,这些城市坚持“环保优先”理念,实施可持续发展战略,出现经济增长与环境质量同步发展的良好状态。与此同时,苏北地区的许多城市摒弃“先污染后治理,边治理边污染”的发展模式,通过一系列行之有效的举措,在加快工业经济发展的同时,城乡生态面貌得到大大改善。江苏在协调经济发展与环境保护方面作出了表率。本期“特别关注”栏目,带你走进“生态现代化”,解读2007年《中国现代化报告》,同时刊登了《如何建设可持续发展的现代化生态城市》、《苏南环境向好提前出现拐点》和《射阳精心打造绿色环保家园》等文章,以飨读者。

基于DEA模型的江西省开发区土地集约利用区域生态效应研究

为了探索江西省开发区土地集约利用对区域生态效应的影响,采用数据包络分析法(DEA),建立了江西省开发区土地集约利用区域生态效应评价模型,分析了全省11个地级市开发区土地集约利用投入与区域生态环境产出之间的关系。研究结果表明,江西省开发区土地集约利用水平对区域生态环境的有效性影响较大,2013-2017年间,只有景德镇市、宜春市和吉安市开发区土地利用现状和土地利用效益对当地生态环境产生积极影响,大部分开发区土地开发建设未能与区域生态环境保护形成有效联动;江西省开发区土地集约利生态效应区域差异明显,2013年开发区土地集约利用对区域生态环境更为有效的地区集中在赣西北,2017年向赣东、赣南集中;作为江西省经济发展水平较高的南昌市、九江市和赣州市,其DEA有效值均不高,开发区土地集约利用水平与当地区域生态环境保护不相适应,土地集约利用投入与区域生态环境产出不协调。     

基于能值理论和生态服务价值的重庆市生态GDP核算

【目的】核算重庆市生态GDP,评估经济增长GDP中资源环境的消耗成本和生态收益,以期将生态理念植入社会经济发展,为经济高质量发展政策的制定提供一定参考。【方法】采用能值分析法和生态服务单位面积价值当量表分别核算资源环境损害价值和生态服务价值,进而从GDP中减去资源环境损害价值再加上生态服务价值后剩余的GDP即为生态GDP,并将重庆市“九五”、“十五”、“十一五”及“十二五”4个规划期的生态GDP与绿色GDP、GDP进行对比分析。【结果】1)资源耗减和环境损害价值从84亿美元增至1419亿美元,资源耗减价值增长明显;2)生态服务价值从490亿美元增长至772亿美元,生态服务价值增长相对较缓慢;3)生态GDP从589亿美元增至1862亿美元。“九五”时期和“十五”时期生态GDP最大,GDP次之,绿色GDP最小;“十一五”时期和“十二五”时期GDP最大,生态GDP次之,绿色GDP最小。【结论】直辖以来重庆市经济持续增长但同时自然资源和生态环境的“透支”较大,即使在得益于一系列生态文明建设政策举措后生态服务价值持续提升下,也难以抵消资源环境损害价值,因此经济高质量发展不仅要加快生态文明建设,也要注重资源高效低耗利用。
     

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.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

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.

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.

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
