THE CORPORATE INTERVIEW AS A RESEARCH METHOD IN ECONOMIC GEOGRAPHY*

The open-ended corporate interview as a qualitative research method is proposed as a valuable component of an evidentiary strategy in economic geography. It is argued to be more sensitive than other survey methods to historical, institutional, and strategic complexity. The corporate interview method is particularly appropriate in periods of economic and social change that challenge traditional analytical categories and theoretical principles. Some problems inherent to the method, and strategies for minimizing their impact on the research project, are described.     

贵州和四川盆地云量的气候研究

贵州和四川盆地是我国云量最多的地区,素有“天无三日晴”和“蜀犬吠日”之说,盆地西缘的雅安古时还有“雅州天漏”的谚语。从全球日照百分率分布推知,川黔地区也是世界上天气最阴沉的地区之一。川黔之阴一向为国内外气象界所注意,本文根据1951—1980     

GMOs and their contexts: A comparison of potential and actual performance of GM crops in a local agricultural setting

In this paper, I argue that genetically modified organisms (GMOs) have inherent potential to contribute to socially and environmentally sustainable agriculture by virtue of their ‘biological embeddedness’. Their actual ‘performance’ and how this contributes to sustainability depends on the ‘mutual shaping’ of technology and context. While much attention has been given to the design context of GMOs, this paper considers the influence of the application context and of users. A case study investigating the use of insect-resistant and herbicide-tolerant GM cotton in the cotton-growing region of New South Wales in Australia is presented. The study was based on focus groups with farmers and other stakeholders in a cotton-growing community. It demonstrated a range of direct and indirect effects of GM cotton use, both positive and negative for sustainability, and the ways in which these effects were influenced by the local social context. The influences of the biotechnology industry context, in limiting the contributions that gene technologies can make to sustainability, were also considered, and remedies suggested. I argue that the polarity of the GM debate is hindering progress on these issues, and that a more balanced approach to our analysis of GMOs is necessary in order to fully understand, and to influence, their role in the future of rural spaces.     

长江中下游金属矿找矿前景与找矿方法

本文论述了长江中下游地区金属矿床的地质、地球物理和地球化学特点,提出今后深部找矿的主要对象是：找隐伏含矿岩体及有关的各类矿体,找岩体中的大型斑岩型矿床,找受岩体和五通砂岩联合控制的层状矿;讨论了地球物理和地球化学方法应用中要注意解决的几个主要问题,强调应发挥包括重力、磁法、激发极化法、电磁法、岩性探测仪及多种天然地震法和化探方法等综合方法的作用,并与地质矿床成矿规律研究密切结合;讨论了方法应用试验中要注意的几个问题。文章最后一部分是从本区大地构造的演化探讨了区域构造岩浆活动与成矿前景,认为这一地区是扬子板块与华北板块陆-陆碰撞挤压造山带及其前陆区,在岩石圈强烈挤压下形成地壳增厚和深部物质的挤出折返,使深部的高压和超高压变质岩层推到地壳浅部;深部生成的柯石英等高压超高压矿物及地幔熔融岩浆同时上侵;生成大量钙碱性岩浆并存储在中地壳部位,通过长期与中下地壳金属物质进行交换,形成矿液的集中优势,通过后期出现的张性断裂构造而进入地壳表层,再经过与围岩发生物理化学成矿作用后沉淀成矿。归纳出扬子板块与华北板块陆-陆碰撞造山带一种新的构造模式。     

埃达克岩研究的回顾和前瞻

文中回顾了中国埃达克岩研究的进展,讨论了中国埃达克岩文献为什么多的原因,归纳了我们取得的成绩及存在的问题,探讨了埃达克岩目前面临的问题和今后研究的方向。笔者认为,中国埃达克岩的研究正处于方兴未艾的阶段,是现阶段国际埃达克岩研究的焦点和中心之一。尽管发表的文章不少,但是研究水平总体不高。在埃达克岩研究中,有大量的问题等待我们去回答,有众多的现象等待我们去解释。中国东部中生代C型埃达克岩的成因、中国东部高原、埃达克岩与青藏高原抬升的关系以及C型埃达克岩与成矿的关系等,应当是今后重点需要关注的问题。     

Marine Ecology - A Century of Changes

Abstract. The major changes within the concepts of marine ecology are investigated, with the aim to design this new journal's scientific format. Four phases of marine sciences are distinguished: the phase of seafarers, of oceanographic expeditions, of marine stations, and of field research. The changes in the latter two are discussed in detail. The changes are described as occurring along three axes. First, as a movement towards the object; accomplished by fieldwork, scientific diving, remote controlled equipment, and by underwater experimentation. Second, the cooperation between several disciplines that led towards bridging gaps. And lastly, how the discovery of unifying principles in ecology (the development of an ecological theory) led the approach in marine ecology towards increasing complexity.     

动力定位系统与单波束测深仪在科考船定点作业中的应用

科考船定点作业时会受到海洋风、涌、浪、流等外界环境因素影响，导致工作效率降低，原位测量精度下降，甚至影响作业安全。动力定位系统 （DP） 具有自动定位功能，能够抵抗外界环境因素的影响，可实现科考船高精度定点控位。 单波束测深仪不仅可以测量水深，也可反映水下设备深度信息，可以起到辅助监控水下设备功能。本文在介绍定点作业施工现状与局限性的基础上，分析 DP 系统与单波束测深仪工作原理，以“向阳红 01”船为载体，在定点作业时开启 DP 系统与单波束测深仪，发现该方法可以提高科考船定点作业工作效率、原位测量精度并保障作业安全，可为其他科考船定点作业提供参考。     

派比安台风对上海黄浦江潮位的影响及成因探讨

2000年派比安台风产生的历史第二高潮位对上海的防汛带来严重影响。本文通过比较历史上的风暴潮，从动力机制、天文高潮与增水极值相碰头，潮波共振和水利工程的影响等四个方面分析了这次风暴潮造成的高水位，及台风余振期边缘波的影响，并用SLOSH（Sea,Lake,Overland Surge from Hurricanes)模式模拟了这次风暴潮，为防台减灾的正确决策提供了理论依据。
