西部中小城市发展空间走廊的综合开发规划研究--以平凉市崆峒大道为例

目的研究西部中小城市过境公路演变为城市道路的现象,揭示其本质内涵,为编制科学合理的综合开发规划提供理论依据。方法通过平凉市崆峒大道综合开发规划实证分析,探讨城市空间走廊综合开发规划的编制。结果空间走廊的综合开发规划,包括总体布局、道路交通体系、绿地景观体系、地块控制性经济技术指标与规划设计条件、沿街建筑景观设计意向等。结论过境公路改造成城市道路必须从城市发展的角度充分关注其两侧用地的功能、结构、形态、交通和景观等诸因素,采用综合开发的手段,为城市的未来发展提供健康的空间走廊。     

川西前陆盆地须家河组沉积相及岩相古地理演化

川西前陆盆地上三叠统须家河组是油气勘探的重点层位.依据新的地层划分方案、大量钻井、露头及岩芯资料,结合区域地质特征,详细研究了须家河组沉积相、岩相古地理特征及其演化.结果表明:研究区内主要发育了冲积扇、湖相三角洲、湖泊、海相三角洲、滨岸和海湾六种主要的沉积相类型;古地理演化经历了由海相环境-海陆过渡相环境-陆相环境的转变;在须四早期,受安县运动的影响,龙门山褶皱成山,使研究区与阿坝海域完全隔绝,整个四川盆地真正进入了陆相沉积环境.     

40Ar-39Ar thermochronology of two ductile shear zones from Yiwulüshan, West Liaoning Region: Age constraints on the Mesozoic tectonic events

Two ductile shear zones trending EW and NNE respectively not only controlled the tectonic framework of the northern North China, but also constrained the geodynamic background for gold mineralization in this region. Field observations and microstructural analyses reveal that the EW trending ductile shear zones are mainly contributed to dextral compressional deformation resulting from top-to-the-southeast oblique thrust shearing, whereas the NNE trending ones are genetically related to sinistral strike-slip and extensional faulting. One sample from the former yielded an ⁴⁰Ar–³⁹Ar plateau age of (219± 4) Ma (Bi) and two samples from the latter gave ⁴⁰Ar–³⁹Ar plateau ages of (116± 2) Ma (Bi) and (127±3) Ma (Bi). These ages provide constraints on the top-to-the-southeast oblique thrusting event occurring in Late Triassic and the sinistral extensional and strike-slip faulting event which occurred in Early Cretaceous.

重庆在西部大开发中的比较优势及战略定位

西部大开发是中国经济结构布局的又一战略性调整。作为西部唯一的直辖市，重庆必须抢占西部大开发的战略制高点。通过与西部10省区的比较分析，重庆在区位因素、综合经济实力、产业基础、市场容量、科教资源、城市功能和交通条件等方面都具有相对优势，由此重庆在西部大开发中的战略定位为西部大开发的重要增长极、长江上游的经济中心，将发挥其战略支撑、对外窗口、辐射带动三大功能。     

西部退耕还林在生态环境建设中的地位与作用

根据中国西部由于自然和人为因素的影响,森林破坏严重,生态环境日趋恶化,经济基础薄弱。自然生态条件较差,发展水平仍然较低,西部各省人均国内生产总值无一达到全国平均水平,已严重的制约国民经济的发展和社会的安定团结的实际情况,分析了森林遭到破坏之后所造成的恶果对整个国民经济持续、快速和健康发展的影响,研究了退耕还林在整治国土中的巨大作用。     

Dealing with a Differentiated Whole: The Philosophy of the WSR Approach

This paper seeks to explore a philosophical ground for the formulation and practice of an Oriental systems methodology, the wuli–shili–renli approach (WSR). Drawing insights from ancient Chinese thought, WSR contends that, in sociotechnical systems design/management, we should investigate and follow wuli, shili, and renli, which constitute a differentiable, dynamic whole. Wuli, shili, and renli condition and determine the fate of our projects, meaning different methods are needed to deal with each differentiable aspect. It also points out that, to deal with wuli, shili, and renli properly, we need to engage in encounters with the "dark side" of Confucianism and with the contemporary tendency of scientism.     

西方对“中国──园林之母”的认识

１００年前,英国园艺学者威尔逊来到中国,在湖北和四川工作了十多年,为英美等西方国家引去了大量的观赏植物,被西方称为“打开中国西部花园的人”。长期的园林工作实践,使他认识到,中国花卉对世界园林艺术的发展作出极其巨大贡献,因而写下了《中国─—园林之母》这样一部颇有见解的著作。他的这一观点,立刻得到西方的普遍认同。而且随着时间的推移,以及我国传出花卉观赏植物的增多,威尔逊观点的依据还在不断被加强、充实。如今,原产我国的奇花异草和风景树木在世界各地的园林和风景名胜争奇斗艳,呈芳溢彩,为美化各国人民的生活作出了巨大的贡献。该文就西方在华的花卉植物引种,及以威尔逊为代表的此种认识的产生和日益为人们所认同的过程作简要的论述。     

The species of Cellaria (Bryozoa: Cheilostomatida) with large avicularia from West Africa

The three species of Cellaria with large avicularia (the size of an autozooid) known from West Africa have been studied: C. atlantida Cook, C. cookae n. sp. and C. salicornioides Lamouroux. All three are figured by SEM. Cellaria cookae n. sp. is mainly distinguished by its avicularium, with arched and pointed rostrum and mandible and a cryptocyst with a rectangular lyrula. Cellaria atlantida is characterised by its bell shaped Cellaria avicularium. The recognition of C. salicornioides var. normani is considered to be unjustified, as the distinctive character, which is the existence of lateral branching, is only a feature of young colonies and tends to disappear later.     

扬弃·改造·复兴──兼评《出路在于向西方乞灵》

中国传统音乐文化与西方音乐文化存在着相对性差距与绝对性差距。清醒地认识到这个事实，在坚持发挥本民族音乐的内在神韵与气质的同时，认真学习西方音乐文化中更丰富地展示人类灵魂的表现体制，才能为中国音乐的发展确定正确的方向，实现民族音乐的全面复兴。
