1地形学和构造学:阐明岩石圈形变的时空模式
构造地貌学提供了103～106年时间尺度范围的资料,弥补了大地测量和传统地质在时间尺度上的差异,将会为人类对岩石圈变形认识做出重大贡献.地表形貌的数字化表示、地表特征的同位素测年技术、控制整个地表物质运动规律的定量化表示等方法的不断发展,使得过去十年中对地形学的研究发生了巨大变革.同时,沉积学也给地表运动带来了重要的制约因素.地球透镜计划将提供更多新的信息,用于探测地幔、地壳和地表过程之间的耦合. 相似文献

色尔腾山山前断裂位于鄂尔多斯块体西北角,控制着临河凹陷（河套盆地西部）的持续沉降。对色尔腾山山前断裂东段与西段转折处构造演化模式的研究,有助于提高对正断层演化规律和区域地震风险的认识。本文在研究区大比例尺活动断裂填图的基础上,通过对重点区域进行无人机微地貌的测量、探槽开挖、钻孔资料与第四纪测年等方法获取数据,并运用构造地质学、地貌学和沉积地层学等理论,综合探讨断层转折处的构造演化模式及地震危险性。通过研究认为,近东西走向的色尔腾山山前断裂西段与北西走向的东段间以三角状的转换斜坡相连。现今的转折点为应力的积累区,具有较高的地震风险。水平拉伸力的持续作用使断层不断向盆地一侧迁移,同时使断裂转折部位更加平滑。 相似文献

Biogeomorphology is an umbrella term given to a highly‐active research area within geomorphology that focusses on the many and varied interactions and feedbacks between organisms and the physical Earth. In the last 25 years this interest has developed and diversified to include the direct and indirect influences of microorganisms, plants, animals and humans on earth surface processes and landform dynamics, and the roles of geomorphology in ecological functioning, resilience and evolution. This Commentary introduces a virtual special issue of 16 research papers and three ‘State of Science’ pieces, illustrating the diversity of the field, its continued theoretical and conceptual progression, and the applied relevance of biogeomorphological science in tackling environmental problems. Collectively, these papers demonstrate the merits of – and opportunities for – biogeomorphology as an inherently integrative science in understanding and managing the complexity of living landscapes.

In a recent editorial Richards (1990) advocated a realist perspective for geomorphology. Scientific realism, defined broadly, is the doctrine that science attempts to generate true knowledge of the observable and unobservable (i.e. non-empirical) aspects of an objective world. Various brands of realism exist; the particular version cited by Richards (1990) has not strongly influenced mainstream philosophy of science. Also, critical rationalism, which Richards (1990) contrasts with realism, fully adopts a realist perspective. In its broadest sense, realism encompasses the entire spectrum of geomorpho-logic research, thus providing a unifying philosophical framework for geomorphology. 相似文献

The Anthropocene is proposed as a new interval of geological time in which human influence on Earth and its geological record dominates over natural processes. A major challenge in demarcating the Anthropocene is that the balance between human‐influenced and natural processes varies over spatial and temporal scales owing to the inherent variability of both human activities (as associated with culture and modes of development) and natural drivers (e.g. tectonic activity and sea level variation). Against this backdrop, we consider how geomorphology might contribute towards the Anthropocene debate by focusing on human impact on aeolian, fluvial, cryospheric and coastal process domains, and how evidence of this impact is preserved in landforms and sedimentary records. We also consider the evidence for an explicitly anthropogenic geomorphology that includes artificial slopes and other human‐created landforms. This provides the basis for discussing the theoretical and practical contributions that geomorphology can make to defining an Anthropocene stratigraphy. It is clear that the relevance of the Anthropocene concept varies considerably amongst different branches of geomorphology, depending on the history of human actions in different process domains. For example, evidence of human dominance is more widespread in fluvial and coastal records than in aeolian and cryospheric records, so geomorphologically the Anthropocene would inevitably comprise a highly diachronous lower boundary. Even to identify this lower boundary, research would need to focus on the disambiguation of human effects on geomorphological and sedimentological signatures. This would require robust data, derived from a combination of modelling and new empirical work rather than an arbitrary ‘war of possible boundaries' associated with convenient, but disputed, ‘golden’ spikes. Rather than being drawn into stratigraphical debates, the primary concern of geomorphology should be with the investigation of processes and landform development, so providing the underpinning science for the study of this time of critical geological transition.

Within and beyond academia, debates around equality, diversity and inclusion (EDI) have been gathering pace. We focus on EDI and geomorphology and address four main questions: (1) why does EDI matter for geomorphology?; (2) what are the barriers to greater EDI in geomorphology?; (3) how can we address these EDI barriers?; (4) can we ensure a resilient future for geomorphology by addressing EDI? At a time of critical environmental, social and economic transition, we contend that addressing EDI is essential for ensuring a resilient geomorphology, defined here as a discipline that is seen to be adapting to these changing external circumstances so that it remains relevant, vibrant and accessible to a wide cross-section of society. Not doing so will limit the intellectual development of geomorphology, incur reputational risk for geomorphological groups and organizations like the British Society for Geomorphology, and ensure that the many potential benefits of geomorphology for science and society remain underutilized at best. © 2020 John Wiley & Sons, Ltd. 相似文献

Three hundred and twenty‐eight geomorphology articles published in the last quarter of the 20th century were cited 20 or more times in Institute for Scientific Information (ISI) indices, as of 15 May 2001. At the close of the 20th century, well‐cited geomorphology is highly multidisciplinary and interdisciplinary with the most dominant fields being in biological, civil engineering, earth science, geography, geological, and soils disciplines. The very strong English‐language bias of well‐cited journal articles creates a geographical bias in study site selection, which may in turn bias geomorphic theory. Water‐based research (fluvial processes and landforms, riparian, drainage basin) dominates well‐cited papers, with the ‘hottest’ subfield in the 1990s being riparian research with a biological emphasis. Over 90 journals publish well‐cited papers, but Earth Surface Processes and Landforms hosts the largest number of well‐cited papers. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

The significance of landforms – the contribution of geomorphology to the World Heritage Programme of UNESCO

This discussion paper addresses the role of geomorphology in designating UNESCO World Heritage properties. Two of the defined criteria employed in the process are explicitly relevant to geomorphology. Criterion (vii) emphasizes the occurrence of superlative natural phenomena, while criterion (viii) directly refers to landforms and on‐going surface processes, along with historical geological values. Superlative natural phenomena may be singular features, but in recent nominations the focus has tended to be on geomorphic diversity over limited areas. Overall, this is a criterion significantly influenced by subjective judgement. The significance of landforms, as included in the wording of criterion (viii), may be considered in three ways. Landforms may be significant for the science of geomorphology itself, and/or for other natural science disciplines, particularly biology and ecology, and/or be of wider cultural significance, including for history, architecture, general landscape aesthetics, art, or religion, underpinning cultural developments. To better determine the conditions to be fulfilled by a property to be considered as geomorphologically significant at the highest global level required for World Heritage listing seems a timely and useful exercise.

An error is pointed out in Robert Horton's (1945) presentation of his ‘slope function’. The history of its apparent non-detection provides an interesting perspective on the development of geomorphology as a science. 相似文献
