馆藏壁画是博物馆藏品中一类特殊的文物。在馆藏大召寺壁画、陕西唐墓壁画等现状调查研究的基础上,本文分析馆藏壁画区别于原址壁画的特殊性,并提出针对馆藏壁画特点进行历史信息与现状调查的内容框架。强调壁画揭取历史、修复史、搬运史和保存环境等历史信息的调查对于认知壁画的重要性:壁画的现状调查包括本体调查和病害调查两部分,能够帮助保护工作者以科学的视角综合评价壁画保存现状。本文分别论述调查各个方面的意义、具体内容和方法。调查结果无疑对于制定保护修复方案具有重要意义,为合理实施保护修复提供科学依据,并为后续研究和档案记录提供基础信息。  相似文献

Aerial photogrammetric surveys are usually expensive and the resolution of the acquired images is often limited. For this reason, different innovative systems have been developed and tested in order to perform a photogrammetric survey in an inexpensive way, with high-resolution images. In this context, one of the most promising acquisition techniques is represented by the use of Unmanned Aerial Vehicles (UAVs) equipped with a digital camera.  相似文献

Abstract

During dredging works for the new London Gateway Port in 2011, fragments of a German Ju 88 bomber were recovered from the Thames Estuary. Subsequent archaeological investigation by Wessex Archaeology, using geophysical survey and divers, resulted in the location of the wreck site and its subsequent recovery under licence in 2012. Post-recovery analysis has enabled it to be identified as a very rare prototype Ju 88T. The aircraft, flown by men of the secretive Luftwaffe special operations unit VOdL, was lost during a reconnaissance mission to record bomb damage at Chelmsford in 1943. The Norwegian fighter ace who shot it down, Marius Eriksen, subsequently achieved fame as a Norwegian skiing champion and actor. The recovery was unusual in that it was carried out as a staged archaeological investigation and in the context of offshore development, where ‘avoidance’ is the usual strategy.  相似文献

This paper aims to characterise the varying magnitudes of landscape disturbance across the WWI battlefield of Verdun, France. Five study sites were surveyed to best reflect the varying degrees of disturbance under common similar environmental characteristics, e.g. bedrock, soil type and topographic position. Disturbance magnitude was determined by counting and measuring the dimensional attributes of craters in two 0.25 hectare plots at each of the five study sites. Additionally, a survey of microtopography was performed at each of the five study sites to record changes in elevation of damaged sites. The spatial character and variation in the magnitude of disturbance at the five disturbance study sites was linked to four variables: (1) location of armies in relation to the front; (2) stagnation of front lines; (3) topographic location of armies; and (4) geologic characteristics of the site.  相似文献

This paper traces the evolution of the environmental implications. Future prospects for tourism in Malta since 1955. Data derived from a questionnaire survey of tourists are used to demonstrate the problems of the industry: discussion focuses on its uneven impact on the Maltese islands, the over‐dependence on British visitors, the seasonality problem, the inadequacies of the infrastructure and the industry are briefly assessed along with marketing strategies.  相似文献

Abstract

Mountain snowline is important as it is an easily observable measure of the phase state of water in the landscape. Changes in seasonal snowline elevation can indicate long-term trends in temperature or other climate variables. Snow-cover influences local flora and fauna, and knowledge of snowline can inform management of water and associated risks. Between 1945 and 2007 voluntary observers collected a subjective record of snow cover across Great Britain called the Snow Survey of Great Britain (SSGB). The original paper copy SSGB data is held by the Met Office. This article details the digitisation of the Scottish SSGB data, its spatial and temporal extents, and a brief example comparison of Met Office snow-lying gridded data. The digitised SSGB data are available from the Met Office authors.  相似文献
