批判实在论在城市空间研究中的应用

批判实在论是一种有关社会科学的哲学理论,它从浅显易懂的本体论出发,抨击了传统科学研究中背离客观实在的种种理想主义倾向,如对“规律性”的迷信、对计量分析方法的过分依赖等。在上世纪80年代批判实在论被引入到西方城市空间研究中、发展为一种新的研究范式,该范式在对传统空间分析研究的批判基础上强调对空间现象的因果机制的阐释,提出了有关因果机制的概念框架,认为只有透过错综复杂的因果关系去把握决定事物的深层结构和机制,才能避免传统研究中常出现的“混乱归因”现象,为此发展了具体研究和抽象研究、深入研究和广泛研究相结合的研究方法,并将其应用于城市空间研究实践中。本研究对批判实在论范式的产生背景和哲学基础等进行了分析,介绍了其理论脉络、方法论和研究实践,并对该范式进行了评价。     

Flood risk perceptions and spatial multi-criteria analysis: an exploratory research for hazard mitigation

The conventional method of risk analysis (with risk as a product of probability and consequences) does not allow for a pluralistic approach that includes the various risk perceptions of stakeholders or lay people within a given social system. This article introduces a methodology that combines the virtues of three different methods: the quantifiable conventional approach to risk; the taxonomic analysis of perceived risk; and the analytical framework of a spatial multi-criteria analysis. This combination of methods is applied to the case study ‘Ebro Delta’ in Spain as part of the European sixth framework project ‘Floodsite’. First, a typology for flood hazards is developed based on individual and/or stakeholders’ judgements. Awareness, worry and preparedness are the three characteristics that typify a community to reflect various levels of ignorance, perceived security, perceived control or desired risk reduction. Applying ‘worry’ as the central characteristic, a trade-off is hypothesized between Worry and the benefits groups in society receive from a risky situation. Second, this trade-off is applied in Spatial Multi-Criteria Analysis (SMCA). MCA is the vehicle that often accompanies participatory processes, where governmental bodies have to decide on issues in which local stakeholders have a say. By using risk perception-scores as weights in a standard MCA procedure a new decision framework for risk assessment is developed. Finally, the case of sea-level rise in the Ebro Delta in Spain serves as an illustration of the applied methodology. Risk perception information has been collected with help of an on-site survey. Risk perception enters the multi-criteria analysis as complementary weights for the criteria risk and benefit. The results of the survey are applied to a set of scenarios representing both sea-level rise and land subsidence for a time span of 50 years. Land use alternatives have been presented to stakeholders in order to provide the regional decision maker with societal preferences for handling risk. Even with limited resources a characteristic ‘risk profile’ could be drawn that enables the decision maker to develop a suitable land use policy.     

FORTRANM在重磁数据处理中的应用

介绍了ＦｏｒｔｒａｎＭ的基本概念和特点。ＦｏｒｔｒａｎＭ是一个支持分布式环境中并行计算的Ｆｏｒｔｒａｎ语言新成员，它在Ｆｏｒｔｒａｎ７７上扩充而成，不仅能支持数据并行程序设计，而且能支持任务并行程序设计。在重磁数据处理中，常常要进行大计算量的运算，如果采用并行计算方法，可以大大提高低档机器的运算能力，降低运算费用，缩短处理周期。本文用ＦｏｒｔｒａｎＭ把ＧＭＰＳ改造成并行计算系统ＧＭＰＳ－ＦＭ，经实际运行，效果良好，最后对测试结果作了分析。     

空间信息的结构、表达及其理解机制

在分析传统地理信息系统理论主要缺陷的基础上,将语言学引入地理信息系统,提出了数字环境下空间信息结构与表达的认识模型——空间信息的语言学模型,探讨了空间信息的语言学特征,主要是语言单位、语法及语义机制,并就其对地理信息系统各环节特别是空间信息的智能化数据处理所产生的影响进行了讨论。     

环境与生态系统资本价值评估的区域范式

在分析现行环境与生态系统服务功能划分和资本价值评估工作存在的问题的基础上，提出了建立生态资产评估区域范式的必要性，介绍了生态资产评估区域范式的基本内容和工作步骤，并以青藏高原为例，划定了陆地环境与生态系统资本价值的空间分布格局。     

从本土到全球网络化的人地关系思维范式转型

早期地理学关于人地关系的研究多基于本土思维,秉持“一方水土养育一方人”的理念。在严重依赖自然资源的传统农业社会,这一理念及其指导下的区域地理研究和区域管理实践,对于促进人与自然的协调发展起到积极作用。随着系统开放程度的增加,规模不等、层级不同的地域系统形成了一个相互依赖、相互耦合的地理网络。每个地域都是这个网络上的节点,地域问题的产生与解决与网络上其他节点有密切关联、与地域系统内外因素紧密相关,地域外因素有时甚至起主导作用。虚拟水、生态足迹、贸易隐含碳排放、资源纽带关系及人地关系远程耦合等概念和方法的提出,标志着人地关系研究范式从本土思维向全球网络化思维转型。依照新的理念和研究范式,传统的本土思维范式及建立在此范式上的相关研究主题（如区域承载力）应该受到重新审视。     

地理大数据为地理复杂性研究提供新机遇

大数据之风自2010年席卷全球,已在科学、工程和社会等领域产生深远影响。本文首先从地理大数据、第四范式以及非线性复杂地理系统3组基本概念出发,剖析上述3组概念之间的科学联系与相互支撑作用,提出大数据和第四范式为地理复杂性研究提供新机遇。其后,探讨如何利用大数据和复杂性科学的理论方法开展地理复杂性研究。基于地理大数据,可以通过统计物理学的系列指标描述现实地理世界的复杂非线性特征,同时,还可利用深度学习、复杂网络、多智能体等方法,实现复杂非线性地理系统的推演和模拟。上述方法对认知地理现象和过程的复杂性,对复杂地理系统的分析、模拟、反演与预测有重要作用。最后,提出地理大数据和复杂性科学相互支撑可能成为21世纪地理学的主流科学方法。

Emerging Geographies of Conservation and Indigenous Land in Australia

International examples of interactions between Indigenous peoples and the new conservation paradigm come mainly from developing countries and suggest divisions over priorities. As a Western settler society, Australia is at a critical time in conservation and Indigenous peoples' rights. Innovative approaches to conservation are promoted. The role and influence of non-governmental organisations is increasing. Indigenous peoples' rights to land are recognised and Indigenous involvement in conservation is growing. Yet, despite Australia being considered a leader in these arenas, particularly the latter, there has been little analysis of the relationship between innovative approaches to conservation and Indigenous Australians under the new paradigm. This paper describes how the spatial manifestations of approaches under the new conservation paradigm and Indigenous land in Australia are creating new geographies. We identify geographies of overlap, dichotomy and absence. The paper identifies research needs into these geographies, including: examining the influence of ‘recognition’ in engagements between conservation and Indigenous Australians; investigating the impacts of approaches under the new paradigm such as scaling-up, territorialism and differing governance structures on Indigenous Australians; and questioning the social responsibilities of the non-governmental organisations towards Indigenous Australians.
