考古地层的三维建模方法在秦始皇帝陵考古勘探中应用尝试

为了更清楚地展示秦始皇帝陵地区考古地层的三维空间关系,并为后期考古工作中空间数据挖掘做准备,借鉴三维地质建模技术,提出了考古地层三维建模方法。基于探孔数据构建了考古地层三维模型。该模型清楚地展示了秦始皇帝陵地区考古地层的三维空间关系,为田野考古数字化工作提供一种新思路、新方法。     

Disaster management takes to the skies: How new technologies are reconfiguring spatialities of power in desert locust management

This article explores how new technologies – such as drones and satellites – are incorporated into disaster management and questions the implications for power relations between disaster authorities and subjects. This is a critical area of research, as the proliferation of aerial and networked technologies has made their use in disaster management and response more common. Although concerns have been raised about the potential use of aerial and networked technologies in the surveillance and spatial discipline of populations by commercial and government actors, few have considered the implications for disaster management. In response, this article turns to geographical literature on necropower, verticality, and planetary spatialities to analyse technological innovations in responses to desert locust upsurges in Kenya. Drawing from qualitative research carried out between February 2020 and January 2021, we explain how desert locust control operations have shifted from horizontal to vertical to networked and planetary in nature through experimentation with new technologies over the past century. We argue that aerial and networked technologies have led to a volumetric shift in desert locust management and response, giving remote and increasingly automated actors who operate ‘above’ greater power over the life and death of populations ‘below’. In making this argument, we adopt a more-than-human perspective to account for how nonhuman entities and lifeforms shape and are subjected to necropolitical disaster management and responses. We conclude by reflecting on what this analytical approach has to offer the study of vertical and volumetric geographies.     

Earth politics: Territory and the subterranean – Introduction to the special issue

The special issue Earth Politics: Territory and the Subterranean explores how and to what political and economic effects people have territorialized the underground. Through studies of a range of activities – from scientific exploration to 3-D geological modeling to laboratory analysis to recreational caving – authors in the issue challenge the idea that the subterranean is a world apart, detached from the sociopolitical worlds of the surface, and instead focus on the complicated relations and processes that remake and weave meaning into often unseen depths. In this introductory article, we situate the issue within expanding literatures on geological materiality, territorial politics, and vertical/volumetric space, and we discuss two overlapping themes running through the issue's articles: the politics of subterranean knowledge production and the politics of subterranean materialities. We conclude by reflecting on the meaning of ‘earth politics’, emphasizing the injustices that derive from – and are sedimented into – dominant modes of knowing and interacting with the matters of the subsurface.
