为了协调历史文化名城保护与城市发展,结合中国传统城市营造理念与文化景观方法探索入遗效应和灾后重建双重影响下的都江堰保护与再生方法.通过对都江堰古城和堰区内外各类要素及其关联性的研究,再构"城堰一体"整体性文化景观体系,为都江堰市总体城市设计提供思路.研究表明,基于要素关联形成的都江堰水利工程与古城的互依共生关系,是城市形态和城市职能诞生、演化的重要动因;目前要素相互独立,依托要素展开的传统城市职能和活动几乎不存在,古城价值和城堰关系没有得到充分展现."城堰一体"整体文化景观的再构和呈现不仅可以重新发掘遗产和城市的共生关系,也能最大化遗产价值,为城市发展注入活力.  相似文献

社会主义市场经济条件下,在城市的发展中,规划是龙头和前提,建设是基础和重点,管理是灵魂和关键,经营是理念和手段。城市经营和城市管理应同时统领着城市的规划和建设过程。目前,北京城市经营的步伐相对滞后,建议以迎奥运为契机,采取以下措施,做好北京的城市经营与管理工作:1)在城市管理中树立正确的城市经营理念;2)完善城市经营机制,尽快制定有关城市经营与管理的总体政策、办法呼法规;3)重点做好奥林匹克公园、中关村科技园区、商务中心区、旧城区等重点区域的经营和管理工作;4)在城市经营与管理工作中充分注意细节,处处体现以人为本的“人文奥运”理念。  相似文献

受气候与水域地理环境的影响及过度的流域开发,肇庆区域洪涝灾害频仍。在古城规划与营建过程中,防洪排涝始终是城市建设的重要内容。文章通过对肇庆古城的系统调研及文献研究,结合古城建设情况与水系规划特征,从古城选址、水系规划、城墙营建、古城工程管理及防洪救灾4方面探讨了古城防洪御灾体系的建设。具体适灾措施有:依据对自然地貌及水系特征的规律认识选择城址,利用城市高程进行适应性布局;建设集障水、疏排、蓄滞为一体的城市水系,形成区域海绵系统,科学调配水资源;利用古代工程技术措施,建造有自抗洪能力的城垣墙体结构;注重由政府主导的工程管理及防洪救灾的非工程性措施结合,从灾前防范管理、灾中抗洪抢险、灾后保障恢复3个环节进行防洪综合管理,以实现对洪水灾害的主动防御。古城规划和建设中形成的城水共生的传统生态观念、系统完备的古城防洪排蓄体系、防救并举的防灾工程管理模式,是古城在自然灾害下的适应性体现,对于当代城市建设与可持续发展具有重要的启示意义。  相似文献

最近 ,城市经营作为一种理念创新已经得到普遍认可 ,各地城市政府和学术界也都纷纷热烈讨论并运用这一理念来促进城市发展和建设。城市的功能包括两个层面 :一是提供“城”的物理功能和社会功能 ;二是提供“市”的经济功能。城市基础设施、市政公用设施等构成了城市的物理基础。目前所讲的城市经营主要是针对城市政府对城市的物理功能和可持续发展功能的经营。从这一层面上来讲 ,城市经营主要是从企业经营的视角运用市场经济手段 ,将城市功能载体、市政公用设施、无形资产等城市资源 ,进行集聚、重组和运营并从中获得资本收益 ,进而再投资到…  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.  相似文献

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。  相似文献

Quality traits in wheat (Triticum aestirum L.) were studied by quantitative trait locus (QTL) analysis in a recombinant inbred line (RIL) population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross (ChSh). Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.  相似文献
