江苏高速公路收费站一次雷击事故分析

本文对2010年8月3日19时30分沿江高速公路张家港收费站一次严重雷击事故的雷暴过程进行诊断分析,并对其防雷工程存在问题进行综合探讨。分析得出:这次雷暴发生在副热带高压边缘环流形势下,虽副热带高压强大,但大幅度东退,面积明显减小,脊线位置和流场也出现调整。江苏上空由西南气流转为西北气流影响,北方有弱冷空气沿西北气流南下,引发江苏降温,为大气不稳定的增强和触发不稳定能量的释放提供重要条件;本文还分析了雷暴与对流参数关系及演变特征,并探究不稳定参数在雷暴发生中的作用。根据现场调查,分析出这次收费站雷击事故在防雷工程方面存在设备接地、等电位、线路屏蔽、电涌保护器设置、安装和接地电阻等问题,最后针对这些问题提出6点防雷工程整改建议。     

大连与辽宁沿海经济带城市互动发展的实证研究

随着辽宁沿海经济带开发上升为国家战略以后,大连作为该城市群的龙头城市,肩负着带动沿海城市乃至整个辽宁省经济发展的重要使命。在基于城市流强度和城市相互作用强度模型的基础上,从不同的层面对大连与辽宁沿海经济带城市群的内在功能联系进行分析,其结果如下：大连市外向功能量和城市流强度居辽宁沿海经济带首位,其他城市普遍较弱;大连与其他城市的经济联系强度较弱,距离因素作用明显;大连市自身综合实力较强,但其核心城市带动作用不突出。最后,针对研究现状,提出一定的对策建议。     

对外开放度与经济增长关系研究——以河南省为例

基于河南对外开放度与经济增长情况,采用指标分析和回归分析方法,利用SPSS13.0统计软件,对河南省的对外开放度与GDP的相关性进行分析。结果表明,对外开放度系数与GDP高度关联,即对外开放促进了河南经济增长,经济增长带动了河南的对外开放。进而提出充分利用中原经济区建设的机遇,在改善投资环境上实现新突破,加快河南经济的对外开放步伐等对策建议。     

Combining historical and new hydrographic data

The NOAA National Ocean Service hydrographic surveys run between 1930 and 1965 have been digitized from the paper smooth sheets. The surveys since 1965 have been collected, processed, and stored in digital form. The new multibeam systems have been used since 1984 to cover over 100,000 square nautical miles of the Exclusive Economic Zone with overlapping swaths of digital soundings. Each of these multibeam surveys may contain millions of soundings. None of the above data has been assigned quality control tags by NOS, but they are stored by survey number, with indexes showing what younger data are available to supersede older data in any area.

Large digital databases, such as the Master Seaftoor Digital Database, are planned in connection with the Defense Hydrographic Initiative. It will be necessary to assign quality control ratings to the soundings in the databases. The detailed survey data may be indexed in the master database but maintained in distributed databases. The databases could supply historical sounding data in digital form for the planning, collection, processing, and evaluation of new survey data.

During the compilation of some bathymetric maps and nautical charts, it is necessary to junction and combine the newer multibeam surveys having total bottom coverage, with the more widely spaced historical data. Precedence is given to the newer hydrographic data, with some older data being removed as needed in order to provide a smooth transition between data sets. In applying multibeam data to nautical charts, it is necessary that actual soundings be positioned properly with respect to bottom contours, which may have been drawn using gridded values. The junctioning of historical and newer data sets is expected to be aided by the use of interactive cartographic workstations.     

我国经济的全球化及其对城镇体系的影响

本文分析了自我国实行开放政策以来,经济加快融入世界经济体系,进出口贸易与利用外资迅速扩展的情况。由于沿海地区与内陆地区社会经济发展水平及区位条件的差异,沿海地区获得更多的发展机会,从而在一定程度上影响了我国城镇体系的变化,加速沿海原有新城镇群的发展,新城镇群的形成,但由此也带来了沿海城镇的外来暂住人口大量增加、交通拥挤、土地利用难以控制以及环境污染加重等问题,城镇之间的竞争多于协调,对城镇体系的发展不利。     

Organisational geographies of power: Introduction to special issue

This paper introduces the special issue ‘organisational geographies of power’ by examining the theoretical and empirical context for debates. It does this, firstly, with reference to existing theoretical work on what power is and does as well as work on the construction of power relations. Building on this, the paper then, secondly, examines the way relational and production network approaches have incorporated power into work on transnational corporations before, thirdly, considering how work on neoliberalism has studied the construction of spatial power relations. In doing this the paper highlights four important questions for future research relating to the practices and spatiality of power, the exercising of power and the situated effects of power relations.

西北干旱区生态重建与人地系统优化的宏观背景及理论基础

本文在系统分析全球干旱区生态重建与人地系统优化宏观环境的基础上,分析了我国西北干旱区生态环境恶化形势和面临的生态重建机遇及挑战。认为生态威胁已上升为全球最大的安全威胁,生物多样性退化速度惊人,许多物种频频告急,诸多脆弱生态区域先后沦为生态灾难区,国家与地区之间的跨国生态掠夺仍在继续,惊人的生态破坏加剧着生态贫困与经济贫困,生态重建引起国际社会关注,生态安全战略成为全球战略重要组成部分。进而把区域可持续发展理论、恢复生态学理论、社会生态学与地生态学理论作为西北干旱区生态重建与经济可持续发展的理论基础。     

Taking Stock: Farmers' reflections on the deregulation of Australian dairying

On 1 July 2000 significant changes to the regulation of Australian dairying came into effect. These changes eliminated subsidies to milk producers and removed barriers to the inter-State trade of dairy products. Victoria's dairy industry group was a powerful proponent of deregulation, because of the comparative advantage that the State's farmers have in production relative to Australia's other milk producers. However, the deregulation of the dairy industry was contested stridently by many stakeholders, particularly farmers and their representative groups in States other than Victoria. Even within Victoria some farmers were equivocal and some were opposed to the regulatory changes. This paper draws on interviews with informants in the Victorian dairy sector to reveal responses to the regulatory changes. The interviews indicate that opinion was divided before deregulation and remains so. The debate was largely between those who saw the regulatory changes as 'inevitable', some of whom thought it would be a 'good thing' and others who accepted, grudgingly, that it was simply going to happen, and those who thought there had to be alternatives that would avoid the expected adverse consequences.
