中国西南贫困地区乡村韧性研究——以重庆市为例

文章聚焦于我国西南贫困地区乡村韧性，以重庆市 120 个抽样村为研究对象，采用熵值法，从经济韧性、社会韧性、工程韧性多维度视角评价重庆市乡村韧性水平。研究发现：①重庆市抽样村庄的乡村韧性平均值为0.46（满分为1），处于中等偏下水平。②重庆市北部地区的乡村韧性水平较高，交通不便、少数民族聚居的东南部地区乡村韧性水平相对较低。③经济韧性水平偏低限制了抽样村的韧性水平，体现在生产资本投入不足、人力资本水平偏低、土地资源禀赋不优。④相较于乡村状态韧性，抽样乡村的响应韧性水平较低，主要原因在于乡村经济子系统与基础设施（减灾防灾）子系统的响应韧性值较低。文章基于研究结果提出了旨在提升我国西南地区乡村韧性的建议。     

文物展柜密封性能检测方法研究

The ventilation rate of a museum showcase is an important indicator for evaluating its sealing performance. In order to evaluate the ventilation rate of a showcase accurately, objectively and scientifically, some details of the detection and evaluation methods were comprehensively studied on the basis of GB/T 36110—2018. The results show that in order to achieve a better fitting effect, the carbon dioxide concentration outside a showcase should be fixed—a fixed concentration between 300 X 10 and 600 X 10 (volume fraction) had little influence on the fitting results. The average ventilation rate of the showcase at each moment was obtained by the numerical calculation method. When the detection time was short, values were unstable and fluctuated greatly; after stabilization, they were close to the fitted ventilation rates. The initial carbon dioxide concentration had a great influence on the fitting results of ventilation rate. The initial concentration of carbon dioxide gas in a showcase should be basically fixed between 20 000 X 10" and 25 000 X 10 ~ (volume fraction) during detection, so that the testing results were comparable. The carbon dioxide mixture in the airtight showcase is relatively uniform, and no obvious dip occurred. The location of detection equipment has little influence on the fitting results of ventilation rate. If the fitted R reaches 0. 9, the results are considered valid, due to various errors in the detection process. © 2023, Sciences of Conservation and Archaeology. All Rights Reserved.     

“长于姜水”、“都陈”与“葬于长沙”——炎帝传说流衍途径考察

在炎帝传说流衍的过程中,逐渐形成其"长于姜水"、"都陈"与"葬于长沙"的说法。诸说之间似乎缺乏必然的联系,但均有历史与文化的渊源。早在先秦时期,炎帝传说在东、西方流传之时,亦有缘起于南方说流行。随着东汉后期"三皇五帝"系统整合工作的完成,以及魏晋时期以现实生活中的帝王为标准,对传说中古帝王的生平事迹、都城、陵墓所在等关键环节的再次整合,尽管依旧保留着相当浓郁的传说色彩,然而炎帝的人格化倾向却日益凸现,这是古代帝王传说演变过程中一个值得关注的历史文化现象。"姜水"、"陈"与"长沙",似乎可以被理解为炎帝传说流衍过程中三个重要的地理标志,各地不同的炎帝传说借此得以整合,最终形成一个与黄帝并称的华夏民族始祖形象。     

馆藏文物预防性保护风险管理的实践与思考——以上海博物馆为例

馆藏文物预防性保护工作在我国经过了二十余年的系统性研究和应用实践,已经取得了重大进步。近年来,上海博物馆在预防性保护工作中引入风险管理理念,通过明确环境信息、风险评估、风险应对和监督检查的流程,降低文物风险,保障文物安全。本文以上海博物馆的两个临时展览为例,从环境信息统计分析、湿度阈值设定与调控策略选择、材料环境安全性评估、展柜密封性能要求等方面阐述了馆藏文物预防性保护风险管理工作的应用实践和研究思考。
